#### Device Description:
The SmartArc module is an extension of PIMRT that adds dynamic arc capabilities. A Dynamic Arc beam is similar to the current Conformal Arc bean but does ot impose the restrictions of a constant does rate or blocking a specific target.
The SmartArc solution utilizes continuous gantry motion in which the field shape defined by a multi-leaf collimator changes during gantry rotation. The dose rate can also be changed during rotation of the gantry.
Creation of a Dynamic Arc beam will be accomplished through a SmartArc optimization. The user will create a default Dynamic Arc beam, enter IMRT, assign objectives and perform a SmartArc optimization to provide an intensity Modulated Arc Treatment )IMAT) plan.
This extends the functionality of the Pinnacle3 Radiation Therapy Planning System (hereafter Pinnacle RTP) that provides radiation therapy planning for the treatment of benign or malignant diseases. When using Pinnacle RTP, qualified medical personnel may generate, review, verify, approve, print and export the radiation therapy plan prior to patient treatment. Pinnacle RTP can provide plans for various radiation therapy modalities including External Beam Treatment, Stereotactic Radiosurgery, and Brachytherapy.
Pinnacle RTP is a software package that runs on a Sun UNIX workstation and consists of a core software module (Pinnacle') and optional software features. These optional software features, commonly referred to as "plug-ins", are typically distributed separate from the core software product (separate CD-ROM). The device has network capability to other Pinnacle RTP workstations and to both input and output devices via local area network (LAN) or wide area network (WAN).
This software automates multi-modality image registration and fusion by overlaying images from CT. MR. PET. PET-CT, and SPECT devices. This feature provides clinicians with the ability to relate, interpret and contour and image's anatomic and functional information.
{2}------------------------------------------------
Image data is imported from CT, MR, PET, PET-CT and SPECT devices using a DICOMcompliant interface. A qualified medical professional uses the Pinnacles RTP for functions such as viewing and analyzing the patient's anatomy, and generating a radiation therapy plan. The following are examples of tasks that may be performed by clinicians when using the Pinnacle2 RTP system:
- Evaluate the treatment plan based on radiation-sensitive structures and the tumor. .
- Combine both geometric and dosimetric planning on the same platform, including CT . simulation data and plans. The CT simulation part of the system is called SmartSim.
- Configure beam variables such as energy, geometry, and beam modifiers such as blocks, . wedges, multi-leaf collimators, bolus and compensators.
- Visualize the beam on a display, initiate the dose computation, and set the weight of each . beam.
- Obtain dose measurements from any Points of Interest (POI). .
- Perform photon and electron physics modeling, dose algorithm and machine . commissioning. This functionality is supported by the Physics Utility Module.
- Evaluate images away from the workstation via a laptop or physician group workstation. .
- Create data for use in conjunction with treatment QA systems. .
- Configure, backup, archive, restore, and scripting. .
- Evaluate Digitally Reconstructed Radiographs (DRRs) on Pinnacle RTP or remote system . using DICOM Secondary Capture (SC) Export.
Once complete. Pinnacle RTP has the ability to transfer the finished plan to other devices used in the therapy process such as Record and Verify, Linear Accelerator (Linac) Workstations and/or 3th Party QA systems.
The following Pinnacle RTP features are also available to assist the clinician with the radiation therapy planning process. These features are distributed on standalone CD-ROM media, and installed onto the Pinnacle RTP workstation. Corresponding instructions for use such as User Guides or Release Notes are also provided to the clinician for each optional feature.
### P3IMRT (Intensity Modulated Radiation Therapy):
PIMRT combines both forward and inverse planning functionality for both static and dynamic treatments. The system determines a plan that satisfies the user's treatment goals through an optimization process. The user's treatment goals are specified as objectives and constraints based on dose distribution characteristics. .
In addition to the above, the following software options are available to facilitate image and/or data import and export between radiation therapy devices such as the imaging camera, Pinnacle RTP and Record & Verify system. DICOM is the acronym for Digital Imaging and Communications in Medicine and is an internationally recognized standard for transferring biomedical information such as images and data between devices or over a network.
{3}------------------------------------------------
### DICOM RT:
DICOM RT software is used to support both Structure Set and Radiation Therapy Plan import and export functions. Structure Sets describe regions and points of interest to other systems. Plan information includes beam geometry and delivery information.
### DICOM Image:
DICOM Image software is used to support image import and export to and from the Pinnacle RTP workstation according to the NEMA DICOM standard, version 3.0. This functionality allows diagnostic imaging devices supporting the DICOM 3.0 standard to interface with the Pinnacle system.
### Indications for Use:
Pinnacle Radiation Therapy Planning System is a computer software package intended to provide support for radiation therapy treatment planning for the treatment of benign or malignant disease processes, using the dynamic multileaf collimator (DMLC) or "sliding window" technique.
Pinnacle Radiation Therapy Planning System assists the clinician in formulating a treatment plan that maximizes the dose to the treatment volume while minimizing the dose to the surrounding normal tissues. The system is capable of operating in both the forward planning and inverse planning modes.
Plans generated using this system are used in the determination of the course of a patient's radiation treatment. They are to be evaluated, modified and implemented by qualified medical personnel.
### Intended Use:
SmartArc is a module for creating intensity modulated arc therapy plans.
### Summary of Technological Characteristics Compared to Predicate Devices:
Pinnacle' SmartArc makes modifications to the existing Pinnacle' Radiation Therapy Planning System version 7.2 (K041577) that add support for treatment planning with Intensity Modulated Arc therapy (IMAT), using dynamic arc beams. A dynamic arc beam is a beam in which the gantry rotates about the patient and the Multi leaf Collimator (MLC) moves continuously, both while the beam is on. An optimization is done to determine the MLC positions as the gantry moves.
Documentation included in this 510(k) Premarket Notification supports the following modifications:
- . Pinnacle2 RTP = introduces the ability to plan with Dynamic Arc Beams and characterize linear accelerators the are capable of delivering them.
- P'IMRT adds the ability to optimize Dynamic Arc Beams within the IMRT module. .
- . DICOM RT - adds the support for the export of Dynamic Arc plans, associated dose grids and QA plans.
{4}------------------------------------------------
Pinnacle3 SmartArc Module incorporates no technological characteristics not currently incorporated into the predicate device: Pinnacle Radiation Therapy Planning system version 7.2 (K041577).
For dose computation, the SmartArc Module uses the existing collapsed-Cone Convolution/Superposition (CCCS) algorithm that is currently used for photon dose computations, including Conformal Arc beams and for final dose computations in IMRT, including DMPO.
CCCS computes dose from first principles, taking into account the effects of beam modifiers, the patient shape and tissue heterogeneities on the dose distribution. It is based on the work by Mackie et al (see reference below). The model consists of four parts:
- . Modeling the incident energy fluence as it exits the accelerator head.
- . Projection of this energy fluence through the density representation of a patient to compute a TERMA (Total Energy Released per unit Mass) volume.
- A three-dimensional superposition of the TERMA with an energy deposition kernel using a . ray tracing technique to incorporate the effects of heterogeneities on lateral scatter. The kernels are precomputed using a Monte Carlo technique.
- Electron contamination is modeled with an exponential falloff which is added to the dose . distribution after the photon dose is computed.
During optimization for IMRT. DMPO or SmartArc, an iterative dose engine is used for increased speed. IMRT and DMPO use a pencil beam algorithm based on the existing CCCS model. SmartArc uses a Singular Value Decomposition (SVD) dose engine, similar to a pencil beam, as described by Bortfeld (see reference below). For any Pinnacle plan, final dose calculation must be done with the CCCS algorithm, due to its superior accuracy.
The ERGO++ Version 1.7 (K080601) solution uses a pencil beam algorithm. The Trilogy™ System with RapidArc (K072916) solution uses a modified pencil beam algorithm known as the Anisoropic Analytical Algorithm. or AAA. as described by Ulmer et al (see reference below). All such algorithms divide the treatment beam into small "pencils" or "beamlets", compute dose separately for each and then sum them up to obtain the dose for the entire beam. Such methods do take patient geometry and tissue heterogeneities into account, but not as fully as a CCCS algorithm, particularly lateral to the beam direction.

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
