Abstract

The present application provides a peak curve rendering method and device. The method includes: detecting an externally input straight line that satisfies preset conditions in the currently displayed image, determining the straight line type of the detected straight line, and determining the straight line A preset algorithm corresponding to the type; use the preset algorithm to determine the CT value of the straight line, and perform peak curve rendering according to the CT value of the straight line. By determining the line type of the line, the CT value of the line can be calculated using the preset algorithm corresponding to the line type, instead of directly using the bilinear interpolation algorithm with relatively high complexity for all lines, so some unnecessary performance can be reduced Loss, improve the rendering speed of the peak curve. In addition, according to different straight line types, selecting a preset algorithm suitable for the straight line type can also improve the calculation accuracy and improve the rendering effect of the peak curve.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a peak curve rendering method and device. Background technique [0002] At present, perfusion imaging technology has been widely used in the field of medical imaging diagnosis. The realization process of perfusion imaging technology is: after injecting contrast agent for the patient, use imaging equipment (such as CT equipment, magnetic resonance imaging (MRI) equipment, positron emission tomography equipment, etc.) For the video image at the time point, the doctor draws a straight line on the video image according to the actual needs, and then uses the bilinear interpolation algorithm to calculate the CT value of each point on the straight line, and uses the CT value of each point on the straight line to perform peak curve rendering, and finally according to The peak curve of each image is calculated for alignment, which provides a reference for clinical resea...
