摘要： The invention provides for a medical instrument (400, 500, 600, 700) comprising a magnetic resonance imaging system (404) and an external beam radiotherapy system (402) for irradiating a target zone (438) of a subject with a beam (442) of ionizing radiation within the imaging zone. The medical instrument further comprises a processor (448) for controlling the medical instrument. Execution of instructions cause the processor to: acquire (100, 200) first magnetic resonance data (458); reconstruct (102, 202) a first magnetic resonance image (460) from the first magnetic resonance data; receive (104, 204) planning data (462), wherein the planning data specifies a spatially dependent radiation dose for the target zone; register (106, 206) the planning data to the first magnetic resonance image; and calculate (108, 208) an external beam dosage plan (468) and a brachytherapy dosage plan (468) using the spatially dependent radiation dose and the first magnetic resonance image.

摘要： The present invention provides a gradient amplifier (300) for a magnetic resonance imaging system, comprising: a power amplifier (310) configured to supply a gradient coil current to a gradient coil (330); a passive filter (320) oupled to the power amplifier and configured to damp a harmonic component of the gradient coil current, wherein an oscillation current caused by oscillation of the passive filter (320) is present in the gradient coil current; and an active power filter coupled between the passive filter and the gradient coil and configured to generate a compensation current to compensate the oscillation current. Through incorporating an active power filter to compensate the oscillation current caused by the oscillation of the passive filter, the power consumption for attenuation of the oscillation current may be decreased prominently, the compensation result for the oscillation current may not be substantively affected by the variations of the gradient coil parameter, and reliability of the gradient amplifier is improved.

摘要： The invention provides for a magnetic resonance imaging system (100) comprising: a magnet (104) for generating a main magnetic field with a homogeneous field zone (108); an antenna (124, 900, 1000) with an imaging zone (126) that has a fixed geometric relationship with portion (119) of a subject (118); a radio frequency system (114, 116, 124) for generating a radio frequency pulse (602); a magnetic gradient field system (110, 112); and a patient support (120, 122) for automatically moving the antenna and the portion of the subject from outside of the homogeneous field zone to within the homogeneous field zone along a movement axis. Machine executable instructions (180, 182, 184, 186, 188) cause a processor (136) controlling the magnetic resonance imaging system to: move the antenna and the portion from outside of the homogeneous field zone to within the homogeneous field zone along the movement axis; control (402) the radio frequency system to repeatedly generate a radio frequency pulse; control (404) the magnetic gradient field system to generate a gradient magnetic field during movement of the subject support only along the movement axis; control (406) the radio frequency system to repeatedly measure the radio frequency signal from the portion of the subject using the antenna; determine (408) a current location (128) of the antenna or of the imaging zone using the radio frequency signal; and control (410) the patient support to decelerate and halt at a predetermined location (109) within the homogeneous field zone using the current location.

摘要： The present invention relates to a method for use in the concurrent display of medical images from different imaging modalities. A system and a computer program product for use in relation to the method are also disclosed. In the method, a primary image and a secondary image from a different imaging modality are fused. In the fused image, a first pixel group from the primary image having primary image data values within a first range are mapped to grayscale image values. A second pixel group from the primary image having primary image data values within at least a second range are identified, and the secondary image data values of corresponding pixels in the secondary image are mapped to color image values in the fused image.

摘要： An radio frequency (RF) transmit module for a magnetic resonance examination system includes a local field monitoring unit that measures a field emitted by an RF transmission element and generates a pick-up coil signal (puc-signal). The puc-signal is amplified and frequency-down-converted by mixing with an oscillator signal. The frequency-down-converted puc-signal and the RF drive signal for the RF transmission element are transferred over a common signal lead. The oscillator signal may also be transferred over the common signal lead.
