The puncturing needle pose detection in CT images with deep learning method.

Abstract

In recent years, a surgical method called IVR (Interventional Radiology) has attracted attention. It is applied to cancer treatment and biopsy, and has the feature of less burden on patients. However, radiation exposure of doctors has become a problem. Therefore, I has been developed the puncture robot that can be operated remotely. The puncture robot has made it possible to reduce the radiation exposure of doctors to zero. Currently, automatic puncture is a major goal of robots. One of the requirements for the realization of automatic puncture is the detection of the posture information of the puncture needle from the CT images. This paper proposes a method for detecting the tip coordinates and orientation of the needle from CT images.
