摘要： While a solid-state detector is not being irradiated with a radiation, unexposed image data R0 are acquired from an exposure area of the solid-state detector and non-exposure image data r0are acquired from a non-exposure area, which is shielded by a shield plate against exposure to the radiation, of the solid-state detector. Then, while the solid-state detector is being irradiated with the radiation through a subject, exposed image data Rn are acquired from the exposure area, and non-exposure image data rn are acquired from the non-exposure area. The exposed image data Rn are corrected according to Rn−R0−(rn−r0) or Rn−R0×(rn/r0).

摘要： A solid-state radiation detector with increased pixel density. The solid-state radiation detector includes multitudes of linear signal wires for detecting recorded image information as image signals, and a signal detection means disposed on an opposing side of the detector substantially orthogonal to the linear signal wires, and connected to the linear signal wires to detect the image signals from the linear signal wires. A connection section of each of the linear signal wires, extending substantially orthogonal to the opposing side, for connection to the signal detection means is disposed such that the distance from the opposing side to each of the connection sections differs with each other.

摘要： The present invention provides a digital x-ray radiographic imaging system. The system is based on a photoconductive detector and an electro-optic light modulator, where the photoconductive detector layer absorbs x-rays that have passed through an object to form an exposure of the object. The absorbed x-rays create a static optical image, which is stored in the electro-optic light modulator, allowing the capture of the optical image to continue over longer time. The optical image is digitized using a scanning system and an external light source. The image is then processed and stored by a computer. After the optical image is recorded, an erasing mechanism is used to reset the system before a new exposure is made.

摘要： A radiation image is read out by causing a linear reading light beam to scan a radiation image sensor, which has a plurality of parallel linear electrodes to output charge signals according to the radiation image upon exposure to a reading light beam in the longitudinal direction of the linear electrodes, and obtaining an image signal by integrating charge signals, output by the respective linear electrodes in response to the scan of the reading light beam. A pulsed light beam which is projected onto the radiation image sensor for a predetermined time in each of the integrating times is employed as the reading light beam, and projection of the pulsed light beam is controlled so that the center of the time for which the pulsed light beam is projected onto the radiation image sensor is earlier than the center of the integrating time.
