摘要： System and method are disclosed for imaging acquisition from sparse partial scans of distributed wide angle. During real time image reconstruction, artificial intelligence (AI) determines if there is enough information to perform diagnostics based on initial scans. If there is enough information from the fractional scans, then data acquisition stops; if more information is needed, then system performs another round of wide-angle sparse scans in a new location progressively until a result is satisfactory. The system reduces X-ray dose on a patient and performs quicker X-ray scan at multiple pulsed source-in-motion tomosynthesis imaging system. The method and system also significantly reduce the amount of time required to display high quality three-dimensional tomosynthesis images.

摘要： A system including an input sensor, a summer, a controller, and a feedback sensor. The input sensor: detects a first amount of force or torque applied on a component of an x-ray scanner gantry in a direction; and generates a command signal. The command signal indicates the first amount of force or torque. The summer generates an error signal based on the command signal and a feedback signal. The controller controls operation of a motor based on the error signal to: reduce the error signal; provide counterbalancing of the gantry in the direction; and provide a net force or torque on the gantry that is equal to a predetermined value or is within a predetermined range of the predetermined value. The feedback sensor detects a second amount of force or torque applied on the gantry in the direction as a result of the controlled operation and generates the feedback signal.

摘要： A method and an imaging system are disclosed. The method, for determining at least one value of at least one recording parameter for a recording of an X-ray image of a patient positioned on an examination table, uses contactless scanning of at least part of the surface of the patient via at least one electromagnetic sensor, to calculate the three-dimensional contour of the scanned surface without additional exposure to radiation. At least one anatomic landmark of the patient can be identified using the three-dimensional contour, and the position of the anatomic landmark is determinable in the coordinate system of the table. The value of the recording parameter is determinable using the position of the anatomic landmark. The value of the recording parameter is determinable quickly and easily since contactless scanning of surfaces can be achieved quickly and easily in terms of technology.
