Cassette and radiation image capturing system
First Claim
Patent Images
1. A cassette storing therein a radiation conversion panel for detecting a radiation emitted from a radiation source that has passed through a patient, and converting the detected radiation into radiation image information, the cassette comprising:
- a detecting unit for detecting a movement of the patient from a given image capturing posture with respect to the cassette during a process of acquiring the radiation image information by emitting the radiation from the radiation source to the patient; and
an image capture inhibiting unit for inhibiting the radiation image information of the patient from being captured,wherein the detecting unit is provided inside the cassette and configured to detect a load applied to the cassette by the patient,the radiation source is configured to continue emitting the radiation toward the patient when the detecting unit detects no load or an amount of movement of the patient is equal to or smaller than an allowable range in relation to an irradiation time of the radiation, andthe image capture inhibiting unit is configured to inhibit the radiation image information of the patient from being captured when the detecting unit detects the amount of movement of the patient greater than an allowable range in relation to the irradiation time of the radiation.

Abstract
A radiation detecting cassette houses therein a detector for detecting a load applied to the radiation detecting cassette when a patient has moved. It is determined whether or not the patient has moved in an image capturing process based on the load detected by the detector. If it is judged that the patient has moved, then a warning is displayed, and a radiation image of the subject is inhibited from being captured.

11. A radiation image capturing system comprising:
-
a radiation source which emits radiation toward a patient; a cassette storing therein a radiation conversion panel for detecting the radiation emitted from the radiation source that has passed through the patient and converting the detected radiation into radiation image information; a detecting unit disposed in the cassette for detecting a movement of the patient from a given image capturing posture with respect to the cassette during a process of acquiring the radiation image information by emitting the radiation from the radiation source to the patient; and an image capture inhibiting unit for inhibiting the radiation image information of the patient from being captured if the patient has moved with respect to the radiation source, based on the movement of the patient detected by the detecting unit, wherein the detecting unit detects a load applied to the cassette by the patient, the radiation source is configured to continue emitting the radiation toward the patient when the detecting unit detects no load or an amount of movement of the patient is equal to or smaller than an allowable range in relation to an irradiation time of the radiation, and the image capture inhibiting unit is configured to inhibit the radiation image information of the patient from being captured when the detecting unit detects the amount of movement of the patient greater than an allowable range in relation to the irradiation time of the radiation. - View Dependent Claims (12, 13, 14, 15, 16, 17)
