Premarket evidence — what FDA accepted

Device typesamd
source quote (p.5)
The subject device with the current software version SOMARIS/8 VB60 is an image analysis software for viewing, manipulation, 3D and 4D visualization, comparison of medical images from multiple imaging modalities and for the segmentation of tumors and organs-at-risk, prior to dosimetric planning in radiation therapy.
AlgorithmAI-based algorithm for the creation of synthetic CT images from MR images, changed from Atlas based to a deep-learning algorithm for brain and pelvis synthetic CTs.
source quote (p.8)
The subject device syngo.via RT Image Suite VB60 includes an AI-based algorithm for the creation of synthetic CT images from MR images to be used in the preparation of radiation therapy treatment planning. The algorithm for brain and pelvis synthetic CTs has been changed from Atlas based to a deep-learning algorithm.

Reported performance (2 observations)

accuracyas written: “geometric accuracy (average deviations in body outline)1
source quote (p.8)
The subject device algorithm demonstrated very good geometric accuracy with average deviations in the body outline smaller than 1 mm, which is below the voxel resolution and therefore not clinically relevant.
accuracyas written: “HU accuracy (soft/bone tissue)stated without value
source quote (p.8)
The HU accuracy of the subject device algorithm was well within 50 HU (200 HU) for soft (bone) tissue.
