摘要:
The objective of the present invention is to effectively improve an image lag phenomenon of a direct conversion detector. The present invention provides an X-ray detector comprising: a lower electrode, formed on a substrate, to which a first driving voltage V1 is applied; an auxiliary electrode, around the lower electrode, to which a second driving voltage V2 is applied; a photoconductive layer formed on the lower electrode and the auxiliary electrode; and an upper electrode, formed on the photoconductive layer, to which a third driving voltage V3 is applied, wherein the third driving voltage V3, immediately following X-ray irradiation switch-off, is a reverse bias voltage.

The present invention relates to a mammography detector consisting of a mammography detector having multiple sensors, such as a high resolution sensor for detecting very small lesions, a high contrast sensor for detecting the exact size of a lesion, a mammography sensor, and a CT sensor; and to a mammography device capable of acquiring 3D images by rotating an X-ray emitting unit and the mammography detector by more than 185 degrees with respect to a breast to be examined. The mammography device includes a main body, a gantry connected to the main body so as to be capable of moving vertically, an X-ray emitting unit mounted on one end of the gantry, and an X-ray detector mounted on the opposite end of the gantry at a position opposite the X-ray emitting unit, and comprises: a first rotating means provided within the main body in order to rotate the gantry; and a pressing means for pressing the breast of a patient while the patient is standing, and including a supporting panel provided on a rotational axis of the first rotating means, and a pressing panel capable of vertical movement on the axis of rotation so as to press the breast on the supporting panel, and connected to the main body while physically separated state from the gantry. The X-ray detector includes a CT sensor, and a 3D image is acquired by rotating the gantry by at least a certain angle, with the pressing means pressing the breast of the patient.
