摘要： An apparatus and method for dynamically controlling the generation of radiation pulses during pulse-type fluoroscopic imaging. Brightness of an image produced by a pulse is detected, converted to a digital value and compared to an acceptable predetermined value range. If the brightness is not acceptable, the pulse rate is reset to a predetermined, relatively fast rate and the energy level for the next pulse adjusted up or down to increase or decrease the brightness as necessary. Once the brightness is found to be acceptable, the pulse rate is returned to the original pulse rate. If it is determined that motion is occurring, the pulse rate will increase to the relatively fast predetermined pulse rate to provide substantially real-time imaging. If the brightness becomes unacceptable for a pulse during the period of motion, the energy level for the subsequent pulse will be adjusted. This technique of pulse control effectively reduces patient dosage and operator exposure to radiation, provides substantially real-time imaging during periods of relative motion and provides rapid image stabilization times.
摘要翻译：一种用于在脉冲型荧光成像期间动态地控制辐射脉冲的产生的装置和方法。检测由脉冲产生的图像的亮度，转换为数字值并与可接受的预定值范围进行比较。如果亮度不可接受，脉冲速率被复位到预定的相对较快的速率，并且下一个脉冲的能量水平被上调或下降以根据需要增加或减少亮度。一旦发现亮度是可以接受的，则脉率被恢复到原来的脉搏率。如果确定运动正在发生，则脉率将增加到相对较快的预定脉冲速率以提供基本上实时的成像。如果在运动期间亮度变得不可接受，则后续脉冲的能级将被调整。这种脉冲控制技术有效地降低了患者剂量和操作人员对辐射的辐射，在相对运动期间提供了基本实时的成像，并提供了快速的图像稳定时间。

摘要： In apparatus wherein a massive component, such as the spot film device of an x-ray table, is driven to various positions with an electric motor drive, a handle is attached to the component for urging it in the desired direction. The handle is attached to the component with beams that flex slightly. A piezoresistive strain gage assembly is mounted on one of the beams for developing an error signal in response to the handle being urged in either direction. The signal is amplified and used to control the power assist driving motor. Means are provided for compensating the vertical component of gravitational force when the handle and the object to which it is attached are angulated. Means are also provided for disabling the drive motor if an electronic element fails.

摘要： A motorized biopsy needle positioner employed in a mammographic needle biopsy system receives coordinate information representative of an identified point of interest within a patient's captive breast under examination and automatically positions a biopsy needle in accordance with that coordinate information to permit insertion of the biopsy needle to the identified point of interest. An offset mode of operation of the motorized biopsy needle positioner automatically positions the biopsy needle in accordance with coordinate information representative of an offset point within the patient's breast that is offset from the previously identified point of interest to permit insertion of the biopsy needle to that offset point. A manual mode of operation of the motorized biopsy needle positioner permits the user to actuate directional keys of a user control unit to position the biopsy needle in one or more directions, as specified by the actuated directional keys.
