摘要： 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.

摘要： 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.

摘要： 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 Δf, 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.
