20100195884 | Method for transforming a distortion-corrected magnetic resonance image, method for carrying out magnetic resonance measurements, and image transformation unit - A method for carrying out magnetic resonance measurements on an examination object in a magnetic resonance system is described. In at least one embodiment, a magnetic resonance image of the examination object previously acquired via the magnetic resonance system is used to determine spatial coordinates in order to control the magnetic resonance system for the magnetic resonance measurement to be carried out. In this case, in order to determine the spatial coordinates, use is made of a distortion-corrected magnetic resonance image generated on the basis of an original magnetic resonance measured image acquired by the magnetic resonance system and transformed in advance into an equivalent measured image on the basis of field inhomogeneity values of the magnetic resonance system. Also described are a method for, in at least one embodiment, transforming a distortion-corrected magnetic resonance image, generated on the basis of an original magnetic resonance measured image acquired by a magnetic resonance system into an equivalent measured image, and a suitable image transformation unit. | 08-05-2010 |

20090037130 | Method for recording measured data from a patient by taking movements into account, and associated medical device - A method is disclosed for recording measured data from a patient by taking movements into account by use of a medical device designed both for recording motion-related measured data, in particular measured data with a high temporal resolution and/or measured data which can be interpolated with regard to movements, using an imaging method and/or by use of at least one sensor element and for recording nuclear medicine measured data, in particular with a relatively low temporal resolution. In at least one embodiment, the method includes recording nuclear medicine measured data by use of the medical device; simultaneously recording motion-related measured data by use of the medical device; determining at least one motion information item relating to at least one movement of the patient and/or at least one movement inside the body of the patient during the ongoing measured data recording by evaluating at least a portion of the previously recorded motion-related measured data by use of a computational device of the medical device; and carrying out motion correction for at least a portion of the nuclear medicine measured data in real-time by use of the computational device in parallel with recording the measured data depending on the at least one determined motion information item. | 02-05-2009 |
20090041318 | Method for recording measured data of a patient while taking account of movement operations, and an associated medical device - A method is disclosed for recording measured data of a patient while taking account of movement operations by way of a medical device that is designed both for recording movement-related measured data, in particular measured data of high temporal resolution and/or measured data that can be interpolated with regard to movement operations, with the aid of an imaging method and/or by means of at least one sensor element, and also for recording nuclear medicine measured data, in particular of lower temporal resolution. In at least one embodiment, the method includes recording nuclear medicine measured data with the aid of the medical device; simultaneously recording movement-related measured data with the aid of the medical device; determining at least one item of movement information relating to at least one movement operation of the patient and/or in the body of the patient by evaluating at least a portion of the recorded measured data of high temporal resolution on the part of a computing device of the medical device; and adapting at least one item of attenuation correction information available for the computing device and serving for reconstructing the nuclear medicine measured data, doing so as a function of the at least one determined item of movement information. | 02-12-2009 |

20140153804 | METHOD FOR EVALUATING IMAGE DATA RECORDS - In an embodiment of a method, a PET image data record, a functional magnetic resonance image data record and a morphological magnetic resonance image data record, the spatial resolution of which is better than that of the functional magnetic resonance image data record, of the target area are recorded with the combination image recording facility, whereby a center of the target structure is localized in the PET image data record. The center is transmitted to the functional magnetic resonance image data record, based on the center the target structure is segmented in the functional magnetic resonance image data record, the segmentation of the target structure in the functional magnetic resonance image data record is transmitted to the morphological magnetic resonance image data record and is improved there within the scope of a fine segmentation. | 06-05-2014 |
20150051476 | METHOD FOR AN EVALUATION OF FIRST IMAGE DATA OF A FIRST IMAGING EXAMINATION AND SECOND IMAGE DATA OF A SECOND IMAGING EXAMINATION AND ALSO A MEDICAL IMAGING SYSTEM WHICH IS DESIGNED FOR CARRYING OUT THE METHOD - A method is disclosed for an evaluation of first image data of a first imaging examination and second image data of a second imaging examination on a patient. In an embodiment, the method includes a provision of first image data of the first imaging examination captured by way of a first imaging apparatus; a provision of second image data of the second imaging examination captured by way of a second imaging apparatus; a determination of first dynamic data on the basis of the first image data as a function of a time; a determination of second dynamic data on the basis of the second image data as a function of a time; and a determination of correlated data of a correlation of the first dynamic data with the second dynamic data. | 02-19-2015 |
