Problems solved by technology

However, the SUV algorithm in the post-processing workstation is relatively old, and studies have confirmed that the old SUV algorithm has obvious inaccuracies in liver edema
In addition, when the lesion area involves multi-layer images, workstation-based SUV analysis requires clinicians to manually record the SUV of each layer to calculate the average or maximum volume-based SUV, which seriously affects the speed of clinical case analysis, and human factors Larger errors lead to larger

Abstract

The present invention discloses a method for generating a standardized uptake value (SUV) based on medical image data. The method comprises the following steps: step one, the medical image data are preprocessed; step two, users select a module of region-of-interest for the preprocessed medical image data in the step one to draw a lesion region; step three, in the module of the region-of-interest,the standardized uptake value is calculated; and step four, the calculated results are subjected to data save. The system and method completely depend on data parameters stored by the system itself, do not require manual input by clinical staff, reduce inaccuracy caused by human factors, do not require the users to record and batch-save each data, save many cumbersome work, reduce an error rate, at the same time can manually divide the lesion region online, automatically complete and save all the required data results, are simple and rapid to operate, and greatly shorten time for clinical research doctors to analyze the data.

Description

technical field [0001] The invention relates to the technical field of post-processing / analysis of medical imaging, in particular to a method and system for generating a standardized uptake value (SUV) based on medical imaging data. Background technique [0002] Positron emission tomography (PET) is a medical imaging modality that allows the extraction of quantitative information related to the biodistribution of metabolically active contrast agents associated with FDG, FET, FLT, FMISO, etc. PET not only allows a visual representation of the distribution of the administered metabolically active contrast agent, but also allows quantification of how much radiopharmaceutical (also called radiotracer) has accumulated in a particular area. Using PET it is possible to determine exactly how much decay from radioisotopes has been counted in a given area. This makes it possible to compare these numbers with PET scans before or after, and to assess whether uptake and retention remain...
