摘要： In a radiation image read-out method using a stimulable phosphor sheet, read-out conditions in final read-out are adjusted based on preliminary read-out image information on a region recognized as an irradiation field. To recognize the irradiation field, sample image signals are extracted from preliminary read-out image signals at a picture element string extending from an end towards the center of the stimulable phosphor sheet. Changes between image density levels represented by the sample image signals are expressed by an approximate equation, and differences between imaginary image density levels calculated by the approximate equation and the actual image density levels are calculated. Or, the image density changes are expressed by approximate equations for picture element groups, and differences between imaginary image density levels calculated by the approximate equations in each picture element group are calculated. Or, intersections of lines represented by the approximate equations and an image density change curve higher than a predetermined density level and represented by the sample image signals are detected, and the intersection nearest to the sheet end is recognized as an edge of the irradiation field.

摘要： In a radiation image recording and read-out system, a radiation image is recorded on a stimulable phosphor sheet by use of an irradiation field stop for defining an irradiation field. The stimulable phosphor sheet is then exposed to stimulating rays which cause it to emit light in proportion to the radiation energy stored. The emitted light is photoelectrically detected, and a data processing is conducted. The data processing is conducted only on image data within the irradiation field. When preliminary read-out is conducted prior to final read-out by use of stimulating rays having stimulation energy lower than stimulation energy of stimulating rays used in the final read-out, the data processing is conducted in the preliminary read-out only on the image data within the irradiation field.
