Title:
RADIATION IMAGE PHOTOGRAPHING/READING DEVICE
Document Type and Number:
Japanese Patent JP3270513
Kind Code:
B2
Abstract:
PURPOSE: To set a proper reading condition corresponding to a photographing state by a simple circuit configuration by determining the reading in condition by referring to data to show a photographing condition in an X-ray device.
CONSTITUTION: When photographing is executed, photographing data (a tube voltage and a tube current of an X-ray tube, an X-ray irradiation period of time, a photographing distance, a photographic method, the kind of a filter, etc.) are transmitted to a control part 17 on the side of a reader 5 from a data transmitting part 4 immediately after photographing. Where, the data transmitting part 4 is constituted of a CPU, etc., in an X-ray device 1. Before reading a photographed radiation image, a reading condition is set by the control part 17. The control part 17 refers to a first table 15 and determines a set value D imparted to a high voltage control part 18, equivalent to a multiplication factor G of a photomultiplier 10. Based on this D, the high voltage control circuit 18 sets a driving voltage of the photomultiplier 10. With such a constitution, a proper reading condition corresponding to a photographing state is set by a simple circuit configuration.
