Abstract

We have proposed a new gelatin phantom for evaluating the spatial resolution of Optical Computed Tomography (OCT), MRI and X-ray CT (X-CT) as a gel dosimeter readout device. In addition, MTF evaluation was conducted using the proposed gelatin phantom. Consequently, 0.19 (MRI), 1.07 (X-CT), 0.88 (0-D OCT), and 0.89 (2-D OCT) were obtained as a results of modulation transfer factor at 0.3 spatial frequency (cycle/mm).
