3D Coordinate Reconstruction from 2D X-Ray Images for Guided Lung Biopsy
Authors: , , , , , , ,
Abstract: Biopsy is a diagnosis technique aiming at the detection of cancerous cells by removing a sample of tissue from the body. Advances in imaging systems lead to more precise biopsy results. Nowadays, Computed Tomography (CT) is one of the standard modalities for the purpose of imaging guided biopsy procedures. However, not all clinics and hospitals have access to CT technology, especially those in developing countries. Conventional radiography (X-Ray) has capabilities to be used as an alternative imaging modality for image guided lung biopsy. X-Ray is more accessible since it is low-cost and is characterized by a lower radiation level compared to CT. Two X-Ray images were taken, one from anterior-posterior position and another from lateral position containing the cancerous cells being the target. The task of the physician then is to mark the target in each image so that subsequently the system will transfer the images into a three dimensional (3D) plot. In this 3D plot, the position of the targeted nodule relative to real life position can be measured. Results show that X-Ray guided biopsy is a functioning alternative for lung cancer biopsy.
