    摘要： Image quality of tomographic images obtained by optical tomographic measurement is improved. Spatial frequency processes are administered on a tomographic image, with the frequency processing properties (high frequency gain) in the scanning direction of a measuring light beam set to be lower than the frequency processing properties (high frequency gain) in the direction of the optical axis of the measuring light beam. For example, a smoothing process that removes high frequency components is administered to the tomographic image only in the scanning direction. Alternatively, a sharpening process that emphasizes high frequency components is administered to the tomographic image only in the direction of the optical axis. As a further alternative, a smoothing process that removes high frequency components is administered to the tomographic image in the scanning direction, then a sharpening process that emphasizes high frequency components is administered to the tomographic image in the direction of the optical axis.

    摘要： A radiation detector is moved along a predetermined axis of movement. Radiation which has passed through a subject is irradiated onto the radiation detector each time the position of the radiation detector changes due to the movement. Signals are read out from the radiation detector each time that radiation is irradiated, to obtain a plurality of radiation images of the subject. Mechanical errors of the radiation detector are detected at each imaging operation, and mechanical error corrected images in which the mechanical errors are corrected are obtained. Amounts of shift of the subject among the mechanical error corrected images are detected, and amounts of movement of the subject during imaging operations are detected based on the amounts of shift.

    摘要： Clearly notifying that a setting error of an imaging plane of a radiation image detector is on the increase. For a radiation image detector having an imaging plane with pixels, disposed in a two-dimensional matrix, for storing charges by receiving radiation according to an amount of radiation received and used to receive radiation transmitted through the same subject each time the detector is shifted and changed in position along a predetermined shift axis, a setting error of the imaging plane, i.e., an inclination of the two-dimensional matrix with respect to the shift axis or the like is detected a plurality of times with the passage of time and, when a fluctuation range of a plurality of setting errors so detected exceeds a predetermined acceptable range, an indication or an alarm so indicating is given.
