SENOGRAPHE ESSENTIAL, PREMIUM VIEW I (PVI)
GE Medical Systems SCS
Retrospective clinical mammography images
Retrospective clinical images from patients with varying breast densities (fatty, dense, and intermediate) were processed with the eContrast algorithm to evaluate clinical image quality and acceptance.
BIRADS 1 or 2 patients with varying breast tissue types (fatty, dense, and intermediate); Sample Size: 6 images (2 fatty, 2 dense, 2 intermediate)
Not applicable for this study
Clinical acceptance of retrospectively processed images
Indications for Use
The Senographe Essential FFDM systems generate digital mammographic images that can be used for screening and in the diagnosis of breast cancer. The Senographe Essential FFDM systems are intended to be used in the same clinical applications as traditional film-based mammographic systems. Premium View is an image-processing algorithm, which increases the visibility of breast structures. The main advantage is to provide a single breast image, where the contrast in the fatty tissues is similar to that obtained by setting WW (window width) and WL (window level) for optimum visualization of fatty tissues, and the contrast in the fibro-glandular tissue is similar to that obtained by setting WW and WL for optimal visualization of fibro-glandular tissues. PVi is an option that can simplify the presentation of mammographic images, improve workflow, and streamline the review process of images with very dark or bright areas by presenting the image with the WW and WL optimized for review with minimal need for the user to make adjustments for the various tissue areas. This could be especially useful with patients who have very thin breasts, very dense breasts, or implants that currently require multiple adjustments of WW and WL to review. eContrast accommodates different customer display preferences in screening and diagnosis, with 5 different levels, while keeping the PVi option for implants. eContrast postprocessing is also available for stereo images.
Device Story
eContrast is a software-only image post-processing option for Senographe Essential Full Field Digital Mammography (FFDM) systems. It processes acquired digital mammographic images to enhance visualization for radiologists. The algorithm applies a series of calculations—collimator detection, pseudo-log transformation, thickness equalization, dynamic range management, and auto-contrast—to optimize brightness, contrast, and sharpness across different tissue types (fatty and fibro-glandular). Radiologists select from 6 levels of contrast strength to suit display preferences. The processed image replaces the raw image on the acquisition workstation screen. By providing optimized visualization in a single image, the device reduces the need for manual window width/level adjustments, streamlining the review process for clinicians and potentially improving diagnostic efficiency across diverse patient breast densities.
Clinical Evidence
Clinical evaluation involved retrospective processing of images from BIRADS 1 or 2 patients, including fatty breasts, dense breasts, and intermediate cases. The study aimed to confirm that images processed with eContrast maintained acceptable clinical image quality. No specific sensitivity/specificity metrics were reported; the evaluation focused on qualitative clinical acceptance.
Technological Characteristics
Software-only image post-processing algorithm. Operates on digital mammographic images acquired by Senographe Essential FFDM systems. Processing pipeline includes collimator detection, pseudo-log transformation, thickness equalization, dynamic range management, and auto-contrast. Reduces dynamic range to 12 bits. Provides 6 levels of contrast strength. Compatible with stereo images.
Indications for Use
Indicated for screening and diagnosis of breast cancer in patients undergoing digital mammography, including those with fatty breasts, dense breasts, thin breasts, or implants.

| Device Description: | The subject of this submission is a software-only option to<br>Senographe Essential Full Field Digital Mammography (FFDM)<br>system called eContrast.<br>eContrast is an image post-processing algorithm that will<br>introduce a modification to the previously approved Premium<br>View (PV) / Premium View i (PVi) (K110798). eContrast<br>processing will offer 6 levels of contrast strength for image<br>viewing, where the desired combination of image sharpness,<br>image smoothness, level of tissue penetration, and level of<br>contrast may be selected by the radiologist. The final image<br>appearance varies according to the selected level.<br>eContrast is a Software only option. |
| Intended Use: | The Senographe DS and Senographe Essential FFDM systems<br>generate digital mammographic images that can be used for<br>screening and in the diagnosis of breast cancer. The<br>Senographe DS and Senographe Essential FFDM systems are<br>intended to be used in the same clinical applications as<br>traditional film-based mammographic systems.<br>Premium View is an image-processing algorithm, which |
| | increases the visibility of breast structures. The main advantage<br>is to provide a single breast image, where the contrast in the<br>fatty tissues is similar to that obtained by setting WW (window<br>width) and WL (window level) for optimum visualization of fatty<br>tissues, and the contrast in the fibro-glandular tissue is similar<br>to that obtained by setting WW and WL for optimal visualization<br>of fibro-glandular tissues. |
| | Premium View I (PVi) is an option that can simplify the<br>presentation of mammographic images, improve workflow, and<br>streamline the review process of images with very dark or<br>bright areas by presenting the image with the WW and WL<br>optimized for review with minimal need for the user to make<br>adjustments for the various tissue areas.

| | eContrast accommodates different customer display<br>preferences in screening and diagnosis, with 5 different levels,<br>while keeping the PVi option for implants. eContrast post-<br>processing is also available for stereo images. |
| Technology: | The eContrast processing is an image post-processing that<br>provides an image display for all breast tissue (fatty and<br>fibroglandular) from the chest to the nipple in a single image.<br>After acquisition, eContrast is applied to the image to create the<br>processed image which then replaces the raw image on the<br>screen of the acquisition workstation. |
| | The main calculations that are applied to create the processed<br>image are: |
| | • Collimator Detection: |
| | This applies a black mask around the useful image area,<br>covering areas which would otherwise be white. It allows more<br>comfortable viewing. |
| | • Pseudo-log Transformation: |
| | This transformation facilitates the manipulation of brightness<br>and contrast during the review. After the transformation, the<br>image dynamic range is reduced to 12 bits, without loss of<br>clinical information. |
| | • Thickness Equalization: |
| | This equalizes the grey level range all over the breast including<br>the tissue not under compression and close to the skin line. |
| | • Dynamic Range Management:<br>This computation locally increases contrast and sharpness for<br>structure of interest. This effect can be reinforced based on user<br>preferences. |
| | • Auto-contrast: |
| | This improves image quality by optimizing brightness levels<br>(window level) and contrast (window width) in the image. |
| Determination of<br>Substantial Equivalence: | Summary of Non-Clinical Tests: |
| | The eContrast option complies with voluntary standards. The<br>following quality assurance measures were applied to the<br>development of the system: |
| | • Risk Analysis |
| | • Requirements Reviews |
| | • Design Reviews |
| | • Testing on unit level (Module verification) |
| | • Integration testing (System verification) |
| | • Performance testing (Verification) |
| | • Safety testing (Verification) |
| | • Simulated use testing (Validation) |
| | Summary of Clinical Tests: |
| | The subject of this premarket submission, eContrast option, included clinical testing to quantify the clinical acceptance of images that had been retrospectively processed with this image processing algorithm. |
| | The subject of this premarket submission, eContrast image processing option, included clinical image evaluation to quantify the clinical acceptance of images that had been retrospectively processed with this image processing algorithm. |
| | The objective of the eContrast clinical evaluation was to determine if the images retrospectively processed with the new processing still provided acceptable clinical image quality. |
| | The evaluation was based on BIRADS 1 or 2 patients with two fatty breasts, two dense breasts, and 2 images that were in between. This was done to show that the image processing would be acceptable across all types of patients as suggested in the Class II Special Controls Guidance Document for FFDM systems. |
| Conclusion: | GE Healthcare considers the eContrast option to be as safe, as effective, and performance is substantially equivalent to the predicate device. |

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
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.
Try it yourself
