Classification: CPC G  A | IPC G

Claim 0:
1. An apparatus for inspecting a target device, the apparatus comprising:
a data communication interface; and
control circuitry configured to:
train an image-based machine learning framework on prosthetic heart valve image data at least in part by:
obtaining image feature data associated with a plurality of reference prosthetic heart valve devices;
obtaining inspection decision data corresponding to the plurality of reference prosthetic heart valve devices, the inspection decision data including failure decision data;
determining correlations between the failure decision data and the image feature data; and
determining a failure prediction model based on the correlations;

receive imaging data of a target prosthetic heart valve device using the data communication interface, the target prosthetic heart valve device comprising a sealing skirt sutured to a frame by a suturing line that follows an undulating shape of struts of the frame;
identify suture features associated with the suturing line based at least in part on the imaging data;
determine whether the suture features are correctly positioned based at least in part on the failure prediction model; and
determine an inspection outcome based at least in part on the determination of whether the suture features are correctly positioned.
