Embodiment 1

[0087] The sorting method used in the matching event determination process of the prior art needs to go through a large number of size comparisons to sort the events to be processed, and the sorting efficiency is low. Therefore, the inventors of the present invention thought of improving the sorting efficiency by reducing the number of comparisons.

[0088] In this embodiment, by establishing a storage area in advance, the events to be processed are first sorted in the storage area, and then sorted in the storage area again. Since the events to be processed are sorted in the storage area, the number of comparisons is relatively small, so the efficiency of sorting is improved.

[0089] refer to figure 2 , figure 2 The flow chart of the coincidence event determination method provided in this embodiment specifically includes:

[0090] Step 201: Establish M storage areas in advance, where M is a natural number.

[0091] Due to the huge amount of event information collected by ...

Embodiment 2

[0150] refer to Figure 4 , Figure 4 The structural diagram of the coincidence event determination device provided for this embodiment may specifically include:

[0151] A building module 401, configured to pre-build M storage areas, where M is a natural number;

[0152] The first acquiring module 402 is configured to acquire event information of more than M events to be processed, where the event information includes occurrence time, occurrence location and energy;

[0153] The first sorting module 403 is configured to sort the M pending events according to the occurrence time, and obtain the sorted M pending events;

[0154] The first putting module 404 is configured to respectively put the sorted M pending events into the M storage areas in sequence;

[0155] The first determining module 405 is configured to determine any event to be processed except the M events to be processed as a target event;

[0156] The second acquiring module 406 is configured to respectively a...

Abstract

An embodiment of the invention discloses a method and a device for coincidence event judgment. The method includes prebuilding M memory areas (M=natural number) and acquiring information including occurrence time, position and energy of events more than M to-be-handled events, then sequencing the M to-be-handled events according to the occurrence time to acquire sequenced M to-be-handled events, putting the sequenced M to-be-handled events into the M memory areas sequentially, sequencing the to-be-handled events according to the M memory areas and acquiring the sequenced to-be-handled events until completing execution of all the sequence processes of the to-be-handled events, acquiring the time coincidence events after performing time coincidence judgment on the sequenced to-be-handled events according to the occurrence time, and acquiring the coincidence events after performing space coincidence judgment on the time coincidence events according to the occurrence position. Sequencing efficiency is high so that coincidence event judgment efficiency is improved.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to a method and device for judging a coincidence event. Background technique [0002] Positron Emission Tomograph (PET) system is an advanced molecular imaging diagnostic equipment in today's medical field. Because it uses radionuclides as tracers, it is also called nuclear medicine equipment. The PET system is currently widely used in the detection of early tumor lesions, the evaluation of the recovery effect of radiotherapy and chemotherapy, and the examination of diseases in the heart, brain and nerve systems, and has irreplaceable advantages in some diagnostic fields. [0003] Select a FDG (Fluoro Deoxy Glucose, deoxyglucose) label containing a positron nuclide as a tracer and inject it into the subject. After entering the human body, the tracer will diffuse into various tissues along with the blood and participate in Metabolic activity of the human body. During this ...
