Abstract

A CT-guided biopsy is a specialised surgical procedure where a needle is used to withdraw a tissue or fluid
specimen from a lesion of interest. The needle is guided while being viewed by the surgeon on a computed tomography (CT) scan. CT guided biopsies expose patients to a high dosage of radiation. They are lengthy procedures and the lack of spatial reference while guiding the needle down the predicted path are some of the difficulties currently encountered. To explore possible approaches to this problem, we investigate the use of two infrared cameras capable of imaging the biopsy needle area. These are then mapped into scaled 3D co-ordinate space using an extension of a previously reported method. The system is able to read, in real-time, infrared data from two cameras and import the data. The result is a scaled 3D estimate of the needle endpoints.
