Embodiment Construction
[0062] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0063] In order to better understand the solutions of the embodiments of the present invention, some words of the embodiments of the present invention are briefly described below.
[0064] In the workflow of a conventional PET-CT system, the usual data acquisition sequence is positioning image data acquisition, CT data acquisition, and PET data acquisition;
[0065] The reconstruction sequence is scout reconstruction, CT reconstruction, and PET reconstruction. Where positioning is like a type of CT.
[0066] The sequence of acquisition + reconstruction is positioning image data acquisition, positioning image reconstruction, CT data acquisition, CT reconstruction, PET data acquisition, and PET reconstruction. Among them, CT reconstruction and PET data acquisit...

The invention discloses a PET-CT system resource management method and a PET-CT system. The method comprises: an operating system to which the PET-CT system belongs dividing a CPU and a memory in theoperating system into a use resource class and a backup resource class; according to the CPU and the memory in the use resource class, allocating the CPU and / or the memory used by each module in the PET-CT; receiving backup resource request information sent by the resource management unit, and allocating a CPU and a memory in a backup resource class to the resource management unit according to thebackup resource request information; the resource management unit acquiring the priority of each module of the PET-CT system in execution, and allocating CPUs and / or memories in the backup resource class to the modules with high priorities based on an allocation strategy; wherein the priority of each module in the PET-CT system is adjusted by the resource management unit according to the execution sequence of the PET-CT system. According to the method, the defects of low speed and high cost of a PET-CT system are reduced.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to a PET-CT system resource management method and a PET-CT system. Background technique [0002] PET (Positron Emission Tomography) stands for Positron Emitter Tomography. It uses nuclides that can emit positrons to label compounds that can participate in blood flow or metabolic processes in human tissues, and obtain images of cross-sectional, coronal and sagittal sections of the human body. CT (Computed Tomography) is an electronic computer tomography scan. It uses X-ray beams to scan the human body together with a highly sensitive detector to obtain images of the cross-section, coronal section and sagittal section of the human body. [0003] PET-CT is a fusion of medical images generated by PET and CT through the combination of the two technologies for the diagnosis of clinical physiology and pathology. [0004] Currently in the field of medical imaging, PET software systems use...
