고해상도 연속절단면 컬러해부영상을 이용한 한국인 성인여성 복셀팬텀 VKH-Woman 개발

초록

The computational human phantom including major radiation sensitive organs at risk (OARs) can be used in the field of adiotherapy, such as the variation of secondary cancer risks caused by the radiation therapy and the effective dose evaluation in diagnostic radiology. The present study developed a Korean adult female voxel phantom, VKH-Woman, based on serially sectioned color slice images of Korean female cadaver. The height and weight of the developed female voxel phantom are 160 cm and 52.72 kg, respectively that are virtually close to those of reference Korean female (161 cm and 54 kg). The female phantom consists of a total of 39 organs, including 27 organs recommended in the ICRP 103 publication for the effective dose calculations. The female phantom composes of 261×109×825 voxels (=23,470,425 voxels) and the voxel resolution is 1.976×1.976× 2.0619 mm3 in the x, y, and z directions. The VHK-Woman is provided as both ASCII and Binary data formats to be conveniently implemented in Monte Carlo codes.
