摘要： A system and a method for acquiring image data of a subject with an imaging system is provided. The system can include a gantry that completely annularly encompasses at least a portion of the subject, which can be positioned along at an isocenter of the imaging system. The system can include a source and a detector positioned within and movable relative to the gantry on a rotor. The system can include a move control module that sets move data for each of the source, detector and rotor that causes the source, detector and rotor to move in a desired motion profile to acquire image data of a portion of the subject off the isocenter of the imaging system.

摘要： The present invention relates to 3D mammography, in which individual images of a breast are taken at different projection angles and a 3D image subsequently synthesized from this image information. According to the invention, a breast to be imaged is arranged locked in a locking means (16, 17) and during the imaging process, the x-ray source (13) is continuously moved with respect to location of the breast and the breast is irradiated at a number of angular positions of the x-ray source (13). During an irradiation period of the imaging process, the locking means (16, 17) is turned as synchronized with the movement of the x-ray source (13). The imaging process preferably further includes such non-irradiation periods during which the locking means (16, 17) is turned in a direction opposite to that when turned as synchronized with the movement of the x-ray source (13) during an irradiation period.

摘要： The present invention relates to an X-ray system and method for generating 3D image data. The X-ray system comprises a radiation detector, a movable X-ray tube assembly and a control unit, wherein in a working state of the system the radiation detector is detachably positioned in a spatially fixed manner and the X-ray tube assembly can be moved into relative positions relative to the radiation detector. Projection images recorded in the relative positions can be processed together with the coordinates of the relative positions using an iterative reconstruction technique or other image processing methods so as to obtain 3D X-ray images. The X-ray tube assembly is attached to a motor-driven movable stand arm and can be displaced using a control unit. The stand base of the movable stand can be positioned in a spatially fixed manner, so that it has a defined fixed position relative to the radiation detector.

摘要： A patient table for a common imaging system including Magnetic Resonance and X-ray retains the patient stationary in position prior to, during and subsequent to the imaging and includes a base, a patient support portion cantilevered from the base and a mattress. The RF posterior coil portions for the head and for the chest can be inserted into and removed from an operating position underneath the head and chest of the patient while patient remains supported. The chest coil is inserted from one edge in a cavity in the mattress which is reinforced by a sleeve. The signal communication cable from the chest coil is routed in front of the mattress and over the mattress so as to not to be exposed at the sides. The head coil is carried on a base plate of the patient support alongside the head support which remains in place.
