Radiation image read-out method and apparatus

摘要

Stimulating rays are linearly irradiated onto an area of a stimulable phosphor sheet, on which a radiation image has been stored by use of a stationary grid. Light emitted by the sheet is detected with a line sensor constituted such that a reciprocal of an array pitch of photoelectric conversion devices is larger than a value two times as large as a spatial frequency of stripe-like grid patterns recorded due to the stationary grid, which spatial frequency is taken with respect to an array direction of the photoelectric conversion devices. Filtering processing for removing the grid patterns is performed on an image signal having been outputted from the line sensor.
