ORTHOGONAL COMPUTED TOMOGRAPHY SYSTEM

摘要

An orthogonal computed tomography (OrthoCT) system for 3D imaging that provides target (e.g. patient) morphological information is presented. The system comprises one or more photon detectors and one or more photon sources. Incoming photon fluxes impinge on the target from opposite directions, with one or several detectors positioned at approximately 90 degrees in respect to the beam axes. We show by simulation, confirmed by experiments, that OrthoCT is capable of providing 3D target density information. Density ratios equivalent or better than those attainable by state-of-the-art tomographic imaging are shown. The simulations also show that these results are obtained with a reduced dose in respect to that delivered by state-of-the-art clinical computed tomography (CT).
