摘要： A CCD-scintillator x-ray image sensor (18) has a high sensitivity at room temperature and a low profile, enabling the use of the x-ray image sensor in most modern mammography x-ray machines. A cassette 10 that encloses the CCD-based x-ray image sensor has the approximate dimensions of 10.5 x 7.7 x 0.6 inches, and is thus form and fit compatible with conventional film-based cassettes. An electronic interface to the cassette requires but a single cable (24) and a standard connector (22) for connection to a CCD sensor electronics unit. The CCD sensor electronics unit interfaces to a computer, such as a conventional personal computer or workstation, having a relatively high resolution display and a provision for digitally recording high-resolution electronic images. The high sensitivity at ambient (room) temperature results from an x-ray scintillator screen (18c) that is coupled to the CCD image sensor (18a) via a bias cut fiber optic faceplate (18b). The CCD image sensor has very low dark current density, high responsivity to the green fluorescence of the screen, and multiple output ports for minimizing the time required for readout and for minimizing the noise bandwidth at the output.

摘要翻译： CCD闪烁体X射线图像传感器（18）在室温下具有高灵敏度和低轮廓，使得能够在大多数现代的乳腺摄影X射线机中使用x射线图像传感器。封闭基于CCD的x射线图像传感器的盒10具有10.5×7.7×0.6英寸的大致尺寸，因此与常规的基于膜的盒形成并配合。到盒的电子接口需要单个电缆（24）和用于连接到CCD传感器电子单元的标准连接器（22）。 CCD传感器电子单元与具有相对高分辨率显示器和用于数字记录高分辨率电子图像的设备的诸如常规个人计算机或工作站的计算机接口。环境温度（室温）下的高灵敏度来自经由偏置切割光纤面板（18b）耦合到CCD图像传感器（18a）的X射线闪烁体屏（18c）。 CCD图像传感器具有非常低的暗电流密度，对屏幕的绿色荧光的高响应度以及多个输出端口，用于最小化读出所需的时间和最小化输出端的噪声带宽。
