Embodiment Construction

[0037] The specific implementation steps of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Refer to attached figure 1 , the concrete steps of the present invention are as follows.

[0039] Step 1. Enter the thyroid planar scintigraphy.

[0040] Input the planar thyroid image of single photon emission computed tomography SPECT to be processed.

[0041] Step 2. Gray-scale the planar imaging of the thyroid gland.

[0042] The first step is to use the gray value calculation formula to calculate the gray value of each pixel in the planar imaging of the thyroid.

[0043] In the embodiment of the present invention, the gray value calculation formula is as follows:

[0044] L i =0.299×R i +0.587×G i +0.114×B i

[0045] Among them, L i Indicates the gray value of the i-th pixel in the thyroid planar imaging image, R i Indicates the red component of the i-th pixel in the thyroid planar imaging image, G ...

Abstract

A human thyroid weight measurement method based on SPECT planar imaging mainly solves the problem of large error and low efficiency in manual delineation of the region of interest in the existing thyroid weight measurement method. The implementation steps are: (1) Input the thyroid planar imaging image; (2) Grayscale the thyroid planar imaging image; (3) Binarize the thyroid planar imaging image; (4) Extract the region of interest ; (5) Calculate the area of ​​the region of interest; (6) Calculate the longest diameter of the left and right half lobes of the region of interest; (7) Calculate the mass of the thyroid gland. The invention has the advantages of ensuring the integrity of the SPECT planar imaging image, effectively segmenting the region of interest and extracting feature information, and quickly calculating the weight of the thyroid gland, and can efficiently complete the weight measurement of the thyroid gland while ensuring accuracy, and can be used for clinical thyroid diseases During the treatment, the dosage was estimated according to the weight of the thyroid gland.

Description

technical field [0001] The invention belongs to the technical field of electronic computing, and further relates to a single-photon emission computed tomography (Single-Photon Emission Computed Tomography) planar image-based method for measuring human thyroid weight in the image data processing technical field. The present invention converts the human thyroid single photon emission computed tomography (SPECT) planar imaging image into gray scale in the clinical thyroid disease treatment process, uses the threshold segmentation method to perform binarization, and then uses mathematical morphological operations to filter and extract the region of interest , so as to calculate the thyroid characteristic value and realize the estimation of human thyroid weight. Background technique [0002] The clinical therapeutic effect in the treatment of thyroid diseases is closely related to the drug dosage. In the process of determining the drug dosage, it is necessary to refer to the pati...
