Premarket evidence — what FDA accepted

Device typesamd

source quote (p.3)

“SIS Software is an application intended for use in the viewing, presentation and documentation of medical imaging, including different modules for image processing, image fusion, and intraoperative functional planning where the 3D output can be used with stereotactic image guided surgery or other devices for further processing and visualization.”

Algorithmmachine learning and image processing to enhance standard clinical images for the visualization of the subthalamic nucleus and proprietary algorithms to generate 3D segmented anatomical models

source quote (p.4)

“SIS Software uses machine learning and image processing to enhance standard clinical images for the visualization of the subthalamic nucleus (“STN”).”

Adaptive (vs locked)No

source quote (p.5)

“The software development was frozen and labeled before tested on this validation set.”

endpoints: average distance between the predicted and the original (on the 7T); overlap between the 3D predicted and the original STN

Retrospective clinical

n=34 patients

endpoints: Center of mass distance; Surface distance; Dice coefficient values

Reported performance (1 observation)

diceas written: “Dice coefficient”0.64

source quote (p.6)

“In addition, the Dice coefficient in this dataset was 0.64, which was expected given the small size of the STN.”

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.
