摘要： An improved x-ray image sensor system and method enables the use of an uncooled or only slightly cooled CCD array (18a) within a standard size x-ray film cassette (10). The sensor system enables the provision of a number of advanced functions such as remote diagnostic capability, variable image resolution, real-time exposure control, automatic x-ray detection, a low-power "sleep" mode, and automatic, closed loop optimization of image quality.

摘要： A CCD sensor structure (304) adapted for backside illumination, has a wide depletion layer (300) separating the illuminated surface (303) from potential barrier-like structures (308), e.g., in the form of a series of p-wells, that shield portions of the CCD channels (301) and that cause the photoelectrons to converge through "ports" between the p-wells into selected regions of the CCD channels (301). The potential barriers (308) are thus arrayed to delineate at the CCD surface (304) a series of charge-packet-forming or integrating regions (307), each of which has two (or more) adjacent shielded charge-packet-holding or storage regions (309) into which the frame-indicative charge packets (314) are successively shifted upon receipt of the light from successive image frames. With an anti-reflective coating (305) on the illuminated back surface (303), this device not only provides 100% fill-factor for each of the successive frames, but also can provide very high quantum efficiency (QE) across the visible spectrum. A preferred embodiment utilizes 7-phase (non-barrier-type) ripple clocking for charge packet (314) readout.
摘要翻译：适于背面照明的CCD传感器结构（304）具有宽泛的耗尽层（300），该被照射表面（303）与潜在的屏障状结构（308）分开，例如以一系列p阱的形式，其屏蔽CCD通道（301）的部分，并且使得光电子通过p阱之间的“端口”会聚到CCD通道（301）的选定区域。因此，势垒（308）排列成在CCD表面（304）处描绘一系列电荷分组形成或积分区域（307），每个区域具有两个（或更多个）相邻的屏蔽电荷包保持或存储区域（309），在从连续的图像帧接收到光时，指示帧的费用分组（314）被连续移动到所述存储区域中。在照明后表面（303）上具有抗反射涂层（305），该装置不仅为每个连续帧提供100％的填充因子，而且还可以在可见光谱上提供非常高的量子效率（QE）。优选实施例利用用于电荷分组（314）读出的7相（非阻挡型）纹波时钟。

摘要： An image sensor device capable of snap shot colour applications comprising an array of image registers (452) for converting the light from successive image frame exposures into indicative charge packets, and an array of light-shielded storage registers (454) interspersed in regular displacements among the array of image registers for receiving the transfer of the charge packets from adjacent image registers over multiple image frame exposures,
whereby, for example, red, green, and blue colour image frames can be acquired upon the opening of a flash exposure shutter, and transferred in parallel into the storage registers from which the three frames can be read out as a colour image when the shutter is closed.

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： A technique and structure is used for producing high resolution color images using a monochrome area charge-coupled device (CCD) 64 and a sequential color illumination scheme. The monochrome CCD 64 comprises a plurality of semiconductor storage cells 76, the semiconductor storage cells 76 being configured in an array having vertical columns 74 and horizontal rows 79. The entire CCD 64 is exposed to a first color image. The charge packets 82 stored in two adjacent horizontal rows as a result of the exposure are then shifted into a third horizontal row. The CCD 64 is then exposed to a second color image. The charge packets 82 stored in the first horizontal row as a result of the second exposure are then shifted into the second horizontal row. The CCD 64 is then exposed to a third and final color image. The CCD output is digitized and stored in a frame. The color information of a particular location on the CCD array 64 is derived by utilizing a simple set of equations.

摘要： An apparatus and method for allowing television systems using solid-state image sensors to be compatible with a multiplicity of television standards. Scenes conforming to a standard which specifies a format aspect ratio or a specific number of active scan lines per frame are input into the anamorphic television system. The anamorphic television system modifies these scenes to take optimum advantage of the resolution of the solid-state image sensor. The anamorphic television system alters the dimensions of the scene along the horizontal and/or vertical axis so that the scene conforms to the format aspect ratio of the solid state image sensor and/or to the number of active scan lines per frame as specified in the applicable standard. The solid-state image sensor converts the optical information into an electrical signal. This electrical signal is retrieved from the solid-state image sensor by timing circuitry. The retrieved electrical information is converted into a composite video signal which is then displayed on the display monitor. The original proportionality of the scene is recaptured by altering the vertical and/or horizontal height controls on the display monitor and/or by altering the rate at which the information is retrieved from the image sensor and displayed on the display monitor.
