MAMMOGRAPHIC APPARATUS

摘要

A mammographic apparatus that includes X-ray detectors configured to detect X-rays entering the X-ray detectors, and attached to a holding-arm placed on a floor. The mammographic apparatus further includes circuitry configured to move the X-ray detectors between a scanning position and a waiting position. The X-ray detectors in the scanning position face an X-ray tube that generates X-rays across a breast-table, and the X-ray detectors in the waiting position are closer to the holding-arm than are the X-ray detectors in the scanning position.

1. A mammographic apparatus comprising:
a breast-table configured to support a breast of a test-subject; a pressure-pad that is translucent, and is configured to press the breast on the breast-table; an X-ray tube configured to generate X-rays towards the breast-table, the X-ray tube facing the pressure-pad across the breast-table; X-ray detectors configured to detect the X-rays going through the breast-table and the pressure-pad; a holding-arm configured to support the breast-table, the pressure-pad, and the X-ray tube; and a detector moving circuit attached to the holding-arm, and configured to move the X-ray detectors between a scanning position and a waiting position, wherein the X-ray detectors in the scanning position face the X-ray tube across the breast-table and the pressure-pad, and the X-ray detectors in the waiting position are closer to the holding-arm than are the X-ray detectors in the scanning position.
