Computed tomography (CT)-compatible remote center of motion needle steering robot: Fusing CT images and electromagnetic sensor data

In the United States and Europe lung cancer screening with low dose computed tomography (CT) is recommended for people at high risk or within clinical trial settings [1,2]. The introduction of lung cancer screening results in an increase of detected nodules. The nodules greater than 10  mm, and small fast-growing nodules would be eligible for clinical work-up, which is often performed with CT-guided lung biopsy. During this procedure the CT system is used to locate the lung nodule and the needle is advanced into the subcutaneous tissue of the chest wall incrementally, and a CT sc an is acquired after every needle manipulation.
