## Indications for Use

MHI-TM2000 Linear Accelerator System is intended for radiation therapy of lesions, tumors and conditions anywhere in the body where radiation treatment is indicated.

## Device Story

MHI-TM2000 (Ver. 3.0) is a linear accelerator for radiation therapy. It builds upon the predicate MHI-TM2000 (K072047) by adding a communication interface to receive real-time position data from an external third-party system (Brainlab ExacTrac Vero). This data enables remote control of the device's existing gimbaled (pan and tilt) mechanism for the X-ray tube and multi-leaf collimator (MLC). By dynamically adjusting the beam axis, the device continuously aligns the treatment beam with moving targets during therapy. The system is operated by clinical staff in a radiation therapy environment. The primary benefit is improved precision in treating moving tumors. The core radiation generation and irradiation methods remain identical to the predicate.

## Clinical Evidence

Bench testing only. Verification testing confirmed system specifications, functional requirements, use cases, and hazard mitigation. Accuracy of the gimbaled (pan and tilt) motion for continuous alignment with moving targets was verified against acceptance criteria.

## Technological Characteristics

Linear accelerator system featuring X-ray-head-mounted gimbals for pan/tilt motion. Includes a new communication board interface for external position data integration. Operates as Image-Guided Radiation Therapy (IGRT) equipment. Software-controlled beam alignment. Sterilization and specific material standards not disclosed.

## Regulatory Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.

## Predicate Devices

- MHI-TM2000 Linear Accelerator System ([K072047](/device/K072047.md))

## Reference Devices

#### 4. Intended Use Statement:

MHI-TM2000 Linear Accelerator System is intended for radiation therapy of lesions, tumors and conditions anywhere in the body where radiation treatment is indicated.

#### 5. Description of the Device:

The MHI-TM2000 Linear Accelerator System (hereinafter called "MHI-TM2000 (VER. 3.0)") has been developed based on MHI-TM2000 Linear Accelerator System previously cleared by FDA under K072047 (hereinafter called "MHI-TM2000 (K072047)").

MHI-TM2000 (VER. 3.0) introduces a new interface functionality for remotely controlling gimbaled motion (pan and tilt motion) of X-ray tube and MLC, based on position data received from radiation therapy positioning system "ExacTrac Vero", which is compatible 3rd party device manufactured by Brainlab AG. This functionality enables continuous alignment of treatment beam with moving target resulting in precise radiation treatment of moving targets.

The gimbal mechanism (pan and tilt) is one of the unique characteristics of MHI-TM2000 (K072047), which is called "X-ray-head-mounted gimbals".

The "X-ray-head-mounted gimbals" have been used to compensate for the residual mechanical deformation, mainly caused by gravity, but the MHI-TM2000 (VER. 3.0) utilizes this mechanism further for moving treatment-X-ray beam axis for continuously aligning it with moving target.

A new interface (communication board) for receiving position data is equipped to System Controller Panel of MHI-TM2000 (VER. 3.0).

The method of generating radiation and irradiation are the same as MHI-TM2000 Linear Accelerator System (K072047).

### 6. Substantial equivalence:

The MHI-TM2000 (VER.3.0) is substantially equivalent to the predicate device: MHI-TM2000 Linear Accelerator System (K072047) of Mitsubishi Heavy Industries, Ltd., as Image-Guided Radiation Therapy Equipment. The intended use, indications for use, scientific technologies.

materials, principles of operation and labeling, are the same or equivalent to MHI-TM2000 Linear Accelerator System (K072047).

### 7. Summary of Performance Testing:

The verification testing results from bench testing support the substantial equivalence of the MHI-TM2000 (Ver. 3.0) with the predicate devices.

The result also ensured conformance to system specifications, functional requirements, use cases, hazard mitigation, as well as compliance with applicable standards.

Accuracy of gimbaled (pan and tilt) motion of X-ray tube and MLC (treatment beam axis) to continuously align with moving target, has also been tested because this is the key function for the new functionality. The results also showed that MHI-TM2000 (Ver.3.0) meet the acceptance criteria.

#### Dear Mr. Wakiyama:

We have reviewed vour Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of

{4}------------------------------------------------

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 1 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450.
