摘要
An imaging apparatus is disclosed for diagnosis, which has multiple transceivers and can perform position correction of a generated tomographic image, based on a distance difference in an axial direction and/or an angular difference in a circumferential direction between the respective transceivers. The imaging apparatus generates an ultrasound tomographic image and an optical tomographic image by using a signal obtained in such a way that a transceiver in which an ultrasound transceiver and an optical transceiver are arranged moves in the axial direction while rotating inside a lumen of a measurement object body. The apparatus generates data for the ultrasound tomographic image and data for the optical tomographic image of a calibration tool having a reflection section. The apparatus calculates the angular difference in the circumferential direction around the axis between the ultrasound transceiver and the optical transceiver, based on positional information of the reflection section.
