Infrared needle mapping to assist biopsy procedures and training

Shar, Bruce and Leis, John and Coucher, John (2018) Infrared needle mapping to assist biopsy procedures and training. Healthcare Technology Letters, 5 (2). pp. 65-69.


A Computed Tomography (CT) biopsy is a radiological procedure which involves using a needle to withdraw tissue or a fluid specimen from a lesion of interest inside a patient's body. The needle is progressively advanced into the patient's body, guided by the most recent CT scan.
CT guided biopsies invariably expose patients to high dosages of radiation, due to the number of scans
required whilst the needle is advanced. This paper details the design of a novel method to aid biopsy procedures using infrared cameras. Two cameras are used to image the biopsy needle area, from which the proposed algorithm computes an estimate of the needle endpoint, which is projected onto the CT image space. This estimated position may be used to guide the needle between scans, and results in a reduction in the number of CT scans that need to be performed during the biopsy procedure. We formulate a 2D augmentation system which compensates for camera pose, and show that multiple
low-cost infrared imaging devices provide a promising approach.
