This invention is related to a method to adjust the starting position of an acquisition trajectory of a mobile X-ray device that is to perform a portable X-ray tomography acquisition sequence. The invention supports an operator in positioning a mobile X-ray device such that it can subsequently successfully and autonomously perform a digital tomosynthesis exam. Alternatively may an operator provide visual input on a camera image on where he desires the tomosynthesis acquisition to be performed, allowing the mobile X-ray device to adjust its initial starting position autonomously.

A method of calibrating a monitoring system (10,14) is described in which a calibration phantom (70) is located with its center located approximately at the isocenter of a treatment room through which a treatment apparatus (16) is arranged to direct radiation, wherein the surface of the calibration phantom (70) closest to an image capture device (72) of the monitoring system (10,14) is inclined approximately 45° relative to the camera plane of an image capture device of the monitoring system. Images of the calibration phantom (70) are then captured using the image capture device (72) and the images are processed to generate a model of the imaged surface of the calibration phantom. The generated model of the imaged surface of the calibration phantom (70) is then utilized to identify the relative location of the center of the calibration phantom (70) and the camera plane of the image capture device (72) which is then utilized to determine the relative location of the camera plane of the image capture device and the isocenter of a treatment room.

A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

An effect of a treatment on an organ, e.g., a lung, is assessed by acquiring a first measurement for each of a plurality of regions of the organ, and then acquiring a second measurement for each of the plurality of regions of the organ, after acquisition of the first measurements. A regional change measurement is obtained for each of the plurality of regions of the organ based on the first measurement and the second measurement of the region. A treatment effect is then determined based the plurality of regional change measurements and treatment information of the treatment delivered to the organ.

In a method for regulating a position of an X-ray focus on the anode of an X-ray source of a scan unit of an X-ray imaging system, a combined actual position of the X-ray focus is determined by a combination of a measured position of the X-ray focus and a model-based position of the X-ray focus, which is determined based on a measured value of a deflection current. On the basis of the combined actual position and a target position, a manipulated variable is determined. On the basis of the determined manipulated variable, a regulation is performed to correct a deviation of the position of the X-ray focus from the target position.
