RSIP Vision, a company that provides artificial intelligence and computer vision solutions for medical imaging, has announced a new panoramic image generator and 3D sparse reconstruction tool for bladder imagery. The tool automatically performs accurate stitching of cystoscopy images of the bladder to create a large panoramic image. The sparse reconstruction verifies that no areas of the bladder go unscreened, and suspicious areas can be revisited.

 “Cystoscopy is a very useful tool for detecting abnormalities in the bladder, and our new panorama tool significantly improves this procedure,” says Ron Soferman, CEO of RSIP Vision. “RSIP Vision’s tool ensures that the region of interest is properly scanned, and the sparse reconstruction allows navigation to points-of-interest easily. Additionally, the module allows accurate measurements of the anatomy and positioning of the camera. Ultimately, this results in a safer and faster procedure.”

Cystoscopies are often used to diagnose lesions and other pathologies in the bladder in symptomatic patients and for surveillance of patients with a history of urothelial carcinoma. The physician continuously repositions the camera within the bladder until convinced that the whole bladder is scanned.

The new reconstruction tool uses “shape from motion” algorithms to get a point-cloud, representing key points on the cystoscopy images. It also creates a panorama of large regions in the bladder. The point-cloud allows verification of complete coverage of the region of interest, as well as a method to accurately revisit specific areas. The tool can also be tailored to any part of the urinary tract through which the cystoscopy camera can pass.

“When examining the bladder for lesions, it is important to completely scan it,” says Arnon Lavi, MD, a senior urologist. “The panorama image verifies that no blind spots remain, reducing the risk for missing a cancerous lesion. Using the sparse reconstruction, we can return precisely to areas of interest for reexamination. This can be used especially in cases of reresection and for surveillance purposes. This tool speeds the procedure and leaves the physician with more confidence in the findings.”
