Positron emition measuring information method for measuring body position and device thereof

Abstract

The invention provides a method used for measuring the positron emission measurement information of a body area which is corresponding to at least a periodic motion process in a positron emission fault angiography category. The invention comprises the steps in which the positron emission measurement in the area to be checked is carried out so as to measure the functional positron emission measurement information; meanwhile, an anatomical imaging method with high time resolution, more particularly the computer fault angiography category method is adopted to collect and restrict the anatomical measurement information of the body area to be checked on a photographing plane at least in a measurement time section, the anatomical imaging method with high time resolution is then adopted to collect and dissect the total four-dimensional data array of the anatomical reference measurement information in at least a motion process period, and the positron emission measurement information in the measurement time section led to be corresponding to the anatomical reference information by the comparison between the anatomical measurement information which is restricted on the photographing plane and belongs to the measurement time section of the positron emission measurement and the four-dimensional anatomical reference measurement information according to the anatomical imaging method.

Description

technical field [0001] The invention relates to a method and an associated device for determining positron emission measurement information of a body part of a subject in the context of positron emission tomography which is relevant to at least one periodic movement process. Background technique [0002] In positron emission tomography, the distribution in the body is tracked by means of a radiolabeled substance introduced beforehand into the organs of the subject in order to obtain the main functional images or data of ongoing biochemical and physiological processes. The temporal resolution of positron emission tomography is rather low compared to other imaging methods. Typically in the case of positron emission tomography the image acquisition takes place in different phases, which are referred to as "beds" and each require an acquisition time in the range of 2 to 5 minutes. Compared to such a longer recording time, a series of movement processes in the body, such as brea...

Problems solved by technology

Here, however, there is the problem that the individual cycles vary in their duration, for example due to physiological influences such as tension, arrhythmia or coughing.

Averaging over time thus becomes particularly complex

In addition, breath-related triggers are not very reliable for various reasons, such as in terms of depth of breath, so that the peak or start point of a cycle is often not identified
