Abstract

The invention relates to a PET colorized tumor body rotary display method, which comprises the following steps: inputting multiple layers of PET two-dimensional grayscale images, and synthesizing a three-dimensional image matrix; segmenting the three-dimensional image matrix, and determining a normal tissue region and an abnormal tissue region; decomposing the three-dimensional image matrix into anormal tissue matrix and an abnormal tissue matrix according to a segmentation result; performing layer-by-layer projection, rearrangement, interlayer interpolation and gray normalization processingon the normal tissue matrix and the abnormal tissue matrix in sequence to obtain a normal tissue rearrangement interpolation normalization matrix and an abnormal tissue rearrangement interpolation normalization matrix; and decomposing the normal tissue rearrangement interpolation normalization matrix and the abnormal tissue rearrangement interpolation normalization matrix into three-color RGB matrixes, adding the three-color RGB matrixes to obtain a four-dimensional matrix, rearranging the four-dimensional matrix, and performing static display and dynamic rotation display (taking the fourth dimension as a rotation angle) of the three-dimensional color matrix on the first three dimensions. The method provided by the invention has relatively high applicability.

Description

technical field [0001] The invention relates to the technical field of tomography, in particular to a method for rotating and displaying a PET colorized tumor body. Background technique [0002] Positron Emission Computed Tomography (PET) images show distribution maps of radiopharmaceutical concentration (or activity) in various tissues and tumor tissues. If the tumor tissue has a stronger specific absorption capacity for a certain drug (that is, the more the drug is absorbed by the tumor tissue, the less absorbed by other tissues), the higher the image contrast, the higher the functional diagnostic value. Generally, areas with higher tissue activity have higher pixel values. For better contrast display, color images are often used instead of grayscale images. On PET color images, the higher the activity of metabolically excited tumor tissue, the warmer the color, such as yellower or even orange-red, called hot spots. Of course, there are also some tissues with reduced me...
