A method and system for accurately determining the SID (source-image-distance) in a radiography configuration with a wireless radiographic detector, and a method and system for determining the thickness of a patient in a radiography configuration. The method for determining the SID is based on a method to accurately determine distances between a set of generator arrays and sensor arrays. The generator arrays and sensor arrays are preferably orthogonally arranged magnetic field generators and sensors that allow measurements of distances without being affected by presence of human tissue between the generator and sensor arrays.

Systems, devices, and methods are presented for automatic tuning, calibration, and verification of radiation therapy systems comprising control elements configured to control parameters of the radiation therapy systems based on images obtained using electronic portal imaging devices (EPIDs) included in the radiation therapy system.

Versatile, multimode radiographic systems and methods utilize portable energy emitters and radiation-tracking detectors. The x-ray emitter may include a digital camera and, optionally, a thermal imaging camera to provide for fluoroscopic, digital, and infrared thermal imagery of a patient for the purpose of aiding diagnostic, surgical, and non-surgical interventions. The emitter may cooperative with an inventive x-ray capture stage that automatically pivots, orients and aligns itself with the emitter to maximize exposure quality and safety. The combined system uses less power, corrects for any skew or perspective in the emission, allows the subject to remain in place, and allows the surgeon's workflow to continue uninterrupted.

There is disclosed a mobile radiographic imaging apparatus including a component operable to emit radiation for imaging a subject, an arm rotatably connected at a proximal end thereof to a body section of the apparatus, such that it is supported by the body section and can slew relative to the body section about an upright axis, and to a distal end of which said component is connected, and a generator assembly arranged in the body section and including a generator arranged in the casing and electrically connected to said component, the apparatus being configured such that the generator assembly rotates with the arm, about said axis, wherein the generator assembly has a centre of mass which is radially offset from said axis in a second direction that is substantially opposite to said first direction.

A method of operating a mobile fluoroscopic imaging system includes positioning an x-ray source and a DR detector about a patient. Data defining a spatial configuration of the x-ray source and the collimator is stored in the system. The system is configured to determine a source-to-image distance of the x-ray source and the DR detector including by activating the x-ray source and capturing a scout image in the DR detector. Dimensions of the scout image are calculated and the source-to-image distance is determined based on the data defining the spatial configuration of the x-ray source and the collimator and on the dimensions of the scout image.
