摘要： A system and method determines an isocenter for an imaging scan. The method includes receiving, by a control panel, patient data generated by at least one sensor, the patient data corresponding to dimensions of a body of a patient. The method includes generating, by the control panel, model data as a function of the patient data, the model data representing the body of the patient. The method includes receiving, by the control panel, a target location on the model data, the target location corresponding to a desired position on the body of the patient for performing the imaging scan. The method includes determining, by the control panel, an isocenter for the imaging scan as a function of the target location.

摘要： A magnetic field z-gradient coil is manufactured by inserting elements (38) into openings (36) on an outside of an insulating carrier (32), wrapping an electrical conductor turn (34) around the outside of the insulating carrier with one side of the wrapped electrical conductor alongside elements inserted into openings on the outside of the insulating carrier, removing the elements alongside the one side of the wrapped electrical conductor from the openings, and repeating to wrap conductor turns of a z-gradient coil (20) around the electrically insulating carrier. A transverse magnetic field gradient coil is manufactured by laying electrical conductor (44) onto a mold (50) with a keying feature (46, 46a) extending along the conductor engaging a mating keying feature (52, 52a) of the mold that defines a winding pattern (56), attaching an insulating back plate (58) to the resulting coil section opposite from the mold, and removing the mold.

摘要： An augmented reality device used in a medical imaging laboratory housing a medical imaging device (10) includes a headset (30), cameras (32, 33) mounted in the medical imaging laboratory, and directional sensors (34, 35, 36, 37) mounted on the headset. The cameras generate a panorama image (54). Data collected by the directional sensors is processed to determine the viewing direction (60). The panorama image and the determined viewing direction are processed to generate an augmented patient view image (80) in which the medical imaging device is removed, replaced, or made partially transparent, the augmented image is presented on a display (40) of the headset. The directional sensors may include a headset camera (34) that provides a patient view image (50), which is augmented by removing or making partially transparent any portion of the medical imaging device in the patient view image by substituting corresponding portions of the panorama image.

摘要： A medical apparatus (100, 300, 400, 800) includes a magnetic resonance imaging system (104), a radiation therapy device (102) having a gantry (106) and a radiation source (110). A radiation detection system (102) measures radiation detection data (174) descriptive of a path and intensity of a radiation beam at an intersection of the radiation beam with at least one surface (144, 144′, 144″) surrounding the subject using at least one radiation detector (144, 144′, 144″). Execution of machine readable instructions causes a processor controlling the medical apparatus to: receive (200) a treatment plan (168), acquire (202) magnetic resonance data (164) from the imaging zone using the magnetic resonance imaging system, generate (204) radiation therapy device control commands (172) using the magnetic resonance data and the treatment plan, irradiate (206) the target zone by controlling the radiation therapy device using the radiation therapy device control commands, measure (208) the radiation detection data during irradiation, and determine a time dependent radiation beam path (176) and a time dependent radiation beam intensity (178) using the radiation detection data.
