AI Technical Summary

Technical Problem

Existing technologies cannot reliably identify organ deformation or movement during resection in soft, deformable and/or mobile organs, and intraoperative imaging methods are expensive and time-consuming, affecting surgical accuracy and patient burden.

Method used

Ultrasonic scanning technology is used to non-contactly acquire the resection surface and register it with the preoperative 3D data set. The resection surface in the 3D model is updated in real time through a tracking system and registration algorithm, avoiding distorted model assumptions and high-cost imaging.

Benefits of technology

It enables precise navigation and real-time updates of the resection surface in soft organs, reducing radiation load and imaging costs for patients, and improving the accuracy and efficiency of surgery.

Abstract

The invention relates to a method (1) for supporting medical staff in an ablation. The invention also relates to a corresponding system (2) and a corresponding computer program product (1, 9). In the method, a preoperative 3D data set (13) of an examination object (3) on which the ablation is to be performed is acquired. Furthermore, an ablation surface (11) is acquired by means of ultrasound in order to generate an ultrasound data set which describes the ablation surface (11). The ultrasound data set is registered to the respective current 3D data set (13). The current 3D data set (13) is updated using the ablation surface (11) acquired by means of ultrasound.
