Abstract: Disclosed is a method and apparatus 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 and for recording nuclear medicine measured data. The method may include 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, and carrying out motion correction for at least a portion of the nuclear medicine measured data by use of the computational device in parallel with recording the measured data.

Abstract: 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.

Abstract: According to a preferred embodiment, the invention provides a method for extracting internal organ motion from positron emission tomography (PET) coincidence data, the method comprising the following steps: generating a data stream of PET coincidence data using the list mode capability of a PET scanner; dividing the data stream into time frames of a given length; computing a histogram A(i, t) of an axial coincidence distribution for a set of time frames; computing the axial center of mass z(t) for each of the time frames in the set of time frames based on the histogram A(i, t); transforming z(t) into the frequency domain; determining either the frequency contribution caused by respiratory motion, given by fresp, or the frequency contribution caused by heart contractions, given by fcard and ?f, identified in the frequency spectrum |Z(f)|; and carrying out further processing of Z(f) leading to curves zresp(t) and zcard(t) with which a gating sequence is established.

Abstract: 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.
