The researchers used 3D ultrasound images in real-time during the simulated surgery to accurately locate, and then the relevant spatial information can guide the surgical machine to complete the task correctly.

The instrument can be assembled on some of the more popular surgical machines to perform minimally invasive laparoscopic surgery on the heart or other organs, said Pratt College graduate student Smith, who participated in the study. In this type of surgery, the surgeon only needs to make a small incision, and then the scanner can provide a clear and realistic image of the surgical organ.

“All the difficulties have been overcome,†Smith said. “All we need to do now is to assemble the scanner onto the surgical instrument. There is no technical obstacle.â€

In addition, 3D scanners allow surgeons to spot tumors in tissue biopsies to avoid missed diagnosis. At present, physicians also need to rely on still images such as CT scans to diagnose suspicious tissues. The researchers also claim that with the development of artificial intelligence technology, the scanner can even guide the surgical machine to complete the surgery without a doctor. Smith added that although the instrument has not been used in patients, they are already eager to conduct clinical trials.
