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

The invention discloses a human body thyroid weight measuring method based on SPECT (Single Photon Emission Computed Tomography) planar imaging, and mainly solves the problem in an existing thyroid weight measuring method that an error is big and efficiency is low since an area of interest is manually drawn. The method comprises the following implementation steps of: (1) inputting a planar imaging graph of the thyroid; (2) carrying out graying on the planar imaging grahp of the thyroid; (3) carrying out binaryzation on the planar imaging graph of the thyroid; (4) extracting the area of interest; (5) calculating the area of the area of interest; (6) calculating the longest diameters of the left and right half leaves of the area of interest; and (7) calculating the quality of the thyroid. The method has the advantages that the integrity of the SPECT planar imaging graph can be guaranteed, the area of interest is effectively segmented, feature information is extracted and the weight of the thyroid is quickly calculated. The thyroid weight measurement can be efficiently finished under a situation that the accuracy is guaranteed, and the method can be used for estimating a drug dosage according to the weight of the thyroid in clinic thyroid disease treatment.

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...
