Abstract: A magnetic resonance tomography unit and a method is provided in which a patient couch may be moved in relation to the longitudinal direction into the patient tunnel in the transversal direction into a left-hand side extreme position and an opposite-lying right-hand side extreme position. Using an image acquisition facility in the left-hand side extreme position a right-hand side part is acquired and in the right-hand side extreme position a left-hand side part of the outer contour of the predetermined object is acquired. Using the image acquisition facility, the outer contour of the object is subsequently created from the left-hand side part of the outer contour and also from the right-hand side part of the outer contour.

Abstract: Misconnected applicators are eliminated in a brachytherapy treatment system by associating the output channels of an afterloader with the channel numbers after the applicators have been coupled to the output channels. In addition, the brachytherapy treatment system ensures the delivery of a proper dose by identifying the exact locations of the distal ends of the applicators right before the radiation treatment is to begin, and determining the final dose based on the exact locations.

Abstract: A system for supporting a brachytherapy treatment includes a medical imaging system and a processing unit. The medical imaging system includes a SPECT unit and/or a CT unit. The processing unit is configured to receive a planning dataset, and determine a brachytherapy treatment plan based on the planning dataset. The treatment plan includes a planned dose distribution for a radiation source. The medical imaging system is configured to acquire a supervision dataset that includes an intra-procedural representation of the radiation source that, in an operating state of the system, has been positioned at a treatment site within a treatment region via a medical guide instrument. The processing unit is configured to register the supervision dataset and the planning dataset, determine an actual dose distribution based on the supervision dataset, and provide supervision information based on a comparison between the planned and actual dose distribution.

Abstract: In a method for acquiring magnetic resonance raw data for image-guided radiotherapy, a number of imaging goals are provided to a computer. For each imaging goal, a magnetic resonance imaging protocol is selected. For each selected magnetic resonance imaging protocol, a number of parameters for that protocol are adjusted according to the respective imaging goal.

Abstract: A method for the reconstruction of a dose administered in an object to be irradiated includes providing a radiation therapy device. The radiation therapy device includes a therapeutic radiation source for emitting a therapeutic treatment beam, a portal detector opposing the therapeutic radiation source for recording measurement data of the treatment beam once the therapeutic radiation source has left the object to be irradiated, and a single or multi slice computed tomography scanner having a kV x-ray source and an opposing kV detector for producing a computed tomography of the object positioned in the radiation therapy device. The method also includes recording a computed tomography image of the object to be irradiated with the computed tomography scanner, and using the computed tomography image in order to reconstruct a dose administered to the object from measurement data of the portal detector.
