摘要： A radiographic imaging apparatus (10) comprises a primary radiation source (14) which projects a beam of radiation into an examination region (16). A detector (18) converts detected radiation passing through the examination region (16) into electrical detector signals representative of the detected radiation. The detector (18) has at least one temporally changing characteristic such as an offset B(t) or gain A(t). A grid pulse means (64) turns the primary radiation source (14) ON and OFF at a rate between 1000 and 5000 pulses per second, such that at least the offset B(t) is re-measured between 1000 and 5000 times per second and corrected a plurality of times during generation of the detector signals. The gain A(t) is measured by pulsing a second pulsed source (86, 100, 138) of a constant intensity (XRef) with a second pulse means (88). The gain A(t) is re-measured and corrected a plurality of times per second during generation of the detector signals.

摘要： A computed tomography method includes rotating an electron beam along an anode (104) disposed about an examination region (112) for a plurality of sampling intervals in which x-ray projections are sampled. The electron beam is swept during each sampling interval to generate a plurality of successive focal spots at different focal spot locations during each sampling interval, wherein the focal spots generated in a given sampling interval include a sub-set of the focal spots generated in a previous sampling interval. The x-ray projections radiated from each of the plurality of focal spots is sampled during each sampling interval. The resulting data is reconstructed to generate volumetric image data.

摘要： An imaging detector includes a scintillator array (202), a photosensor array (204) optically coupled to the scintillator array (202), a current-to-frequency (I/F) converter (314), and logic (312). The I/F converter (314) includes an integrator (302) and a comparator (310), and converts, during a current integration period, charge output by the photosensor array (204) into a digital signal having a frequency indicative of the charge. The logic (312) sets a gain of the integrator (302) for a next integration period based on the digital signal for the current integration period. In one instance, the gain is increased for the next integration period, relative to the gain for the current integration period, which allows for reducing an amount of bias current injected at an input of the I/F converter (314) to generate a measureable signal in the absence of radiation, which may reduce noise such as shot noise, flicker noise, and/or other noise.
摘要翻译：成像检测器包括闪烁体阵列（202），光学耦合到闪烁体阵列（202）的光电传感器阵列（204），电流 - 频率（I / F）转换器（314）和逻辑（312）。 I / F转换器（314）包括积分器（302）和比较器（310），并且在当前积分周期期间将由光电传感器阵列（204）输出的电荷转换成具有指示电荷的频率的数字信号。逻辑（312）基于当前积分周期的数字信号，为下一个积分周期设置积分器（302）的增益。在一种情况下，相对于当前积分周期的增益，下一积分周期的增益增加，这允许减少在I / F转换器（314）的输入处注入的偏置电流的量，以产生可测量在没有辐射的情况下发出信号，这可以减少诸如散粒噪声，闪烁噪声和/或其它噪声的噪声。

摘要： A diagnostic imaging system includes a stationary gantry (20) which defines a subject-receiving bore (26). First and second lasers (66, 68) are firmly mounted to the stationary gantry (20). A saggital laser (48) is mounted overhead to project a longitudinal line (58) on a top of the subject in a vertical plane (60) which is parallel to an axial direction (Z). A couch (36) moves a subject into the bore (26) to generate an image of a region of interest and out of the bore for marking. A user segments the image to outline at least an organ. An isocenter (94) of the segmented organ is determined. At least one of the saggital, first and second lasers (48, 66, 68) are adjusted concurrently with adjusting the couch (36) such that laser lines (58, 76, 78) projected by the saggital, first and second lasers (48, 66, 68) intersect the determined isocenter (94). The saggital, first and second lasers (48, 66, 68) laser mark the subject.
