The summary describes a system that uses additional hardware and software for attenuation correction, but there is no mention of AI, ML, or related concepts. The performance studies compare the system to existing methods, not to AI/ML-based approaches.
No
The device aids in image correction for diagnostic purposes, not for treating diseases or conditions.
No
The device is described as an "attenuation correction system" that generates "corrected NM images" to improve the uniformity of images. Its purpose is to correct images, not to provide a diagnosis from them.
No
The device description explicitly states it comprises "additional hardware and software".
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "To obtain attenuation corrected Nuclear Medicine images." This describes a process of image correction and enhancement, not a diagnostic test performed on biological samples in vitro (outside the body).
- Device Description: The device is an "addition to the Apex VariCam and Millennium VG gamma cameras." Gamma cameras are used for in vivo imaging, where a radioactive tracer is administered to the patient and detected by the camera.
- Nature of the Output: The output is "corrected NM images." These are images of the patient's internal organs or tissues, not results from a test performed on a biological sample.
IVD devices are specifically designed to perform tests on biological samples (like blood, urine, tissue) to diagnose diseases or conditions. This device is clearly focused on improving the quality of in vivo imaging data.

Intended Use / Indications for Use
The intended use of the device is to produce attenuation-corrected NM images, even when attenuation coefficients are not uniform over the FOV.

Device Description
The VTransACT attenuation correction system is an addition to the Apex VariCam and Millennium VG gamma cameras (K953801). It comprises additional hardware and software to generate corrected NM images for non-uniform attenuation.
The VariCam (K953801) gamma camera has been modified to accommodate for the VTransACT attenuation correction system, by including an additional correction map for attenuation, obtained by two scanning line sources attached to the heads of the camera. This map is used to create an attenuation-corrected image.

Identification. An emission computed tomography system is a device intended to detect the location and distribution of gamma ray- and positron-emitting radionuclides in the body and produce cross-sectional images through computer reconstruction of the data. This generic type of device may include signal analysis and display equipment, patient and equipment supports, radionuclide anatomical markers, component parts, and accessories.(b)

TransACT option for the Apex CardiaL Gamma Camera K952674
Device Description
The VTransACT attenuation correction system is an addition to the Apex VariCam and Millennium VG gamma cameras (K953801). It comprises additional hardware and software to generate corrected NM images for non-uniform attenuation.
Description of Change or Modification
The VariCam (K953801) gamma camera has been modified to accommodate for the VTransACT attenuation correction system, by including an additional correction map for attenuation, obtained by two scanning line sources attached to the heads of the camera. This map is used to create an attenuation-corrected image.
Intended Use of Device
The intended use of the device is to produce attenuation-corrected NM images, even when attenuation coefficients are not uniform over the FOV.
Summary of Studies
Bench data and Clinical data show that the VTransACT option for the VariCam delivers more uniform images than regular SPECT without attenuation correction. Comparison to TransACT images shows no significant difference.
Conclusion
In the opinion of ELGEMS Ltd., the VTransACT is substantially equivalent in terms of safety and effectiveness to the TransACT option for the CardiaL (K952674). The VTransACT has the same intended use as the predicate device and no new safety or effectiveness concerns are raised.

Dear Mr. Friedman:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 either class II (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Ouality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP result in reculatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to beein marketing your device as described in your 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.
