Modifications on CT-Scans for the computation of an anatomical atlas of the human chest

Abstract Ultrasound Tomography (UST) and Electrical Impedance Tomography (EIT) images can be computed using Baye’s inference. Prior information is required for the solution of these two inverse problems. In order to build prior information of the human chest, the use of already taken CT-Scans is recommended because radiation exposure will be avoided. CT-Scans are taken with the arms above the head. UST and EIT images are taken with the arms below the head. The present work shows that the movement of the scapula intersects the plane of transducers of the UST or the plane of electrodes in EIT. It is necessary to correct the position of the scapula before the use of a CT-Scan to build an antomical atlas for lung monitoring.
