Embodiment 1

[0065] Such as figure 1 As shown, this embodiment provides a method for correcting a distorted bone image.

[0066] Under normal circumstances, there are two situations in which the patient takes a whole-body bone scan image and causes the distortion of the shoulder and neck. One is that when the patient undergoes a whole-body bone scan, the distortion of the shoulder and neck in the captured image is often caused by the distortion of lying down; the other is that the shoulder and neck are deformed due to certain diseases or external factors during the development of the patient. Therefore, the correction of the shoulder and neck for the patient becomes the basis of the deformed bone correction technology.

[0067] For shoulder and neck correction, this section presents a rotational correction method. Its specific method steps are as follows:

[0068] S1. Obtain a whole-body bone scan image.

[0069] After obtaining the whole-body bone scan image, perform data denoising: w...

Embodiment 2

[0103] Such as Figure 7 As shown, the present embodiment provides a system for correcting a distorted bone image, and the system includes:

[0104] An image acquisition module M1, configured to acquire whole-body bone scan images;

[0105] The left and right shoulder acquisition module M2 is used to respectively acquire the left shoulder position and the right shoulder position in the whole body bone scan image;

[0106] The inclination angle calculation module M3 is used to obtain the inclination angle of both shoulders according to the line connecting the left shoulder position and the right shoulder position;

[0107] The shoulder and neck correction module M4 is used to rotate the whole body bone scan image according to the inclination angle to perform shoulder and neck correction;

[0108] The midpoint abscissa acquisition module M5 is configured to obtain the midpoint abscissa of each row of effective pixels in the whole-body bone scan image to obtain midpoint absciss...

Abstract

The invention relates to a distorted skeleton image correction method, and relates to the technical field of image processing, and the method comprises the steps: obtaining the inclination angles of two shoulders according to the positions of the two shoulders; rotating the image according to the inclination angle, and performing shoulder and neck correction; then acquiring a spine datum line and a midpoint abscissa of each row of effective pixels in the image, and performing spine correction on the part above the pelvis according to the spine datum line and the midpoint abscissa, so that the correction technology is divided into two parts of shoulder and neck correction and spine correction, and different and targeted correction methods are performed for the two parts; therefore, the correctness of the distorted skeleton image is ensured, and the operation is simple and fast.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for correcting a distorted bone image. Background technique [0002] For lung cancer SPECT whole-body bone imaging images, it is necessary to first extract the whole-body bone contour features of the SPECT whole-body bone imaging images, and then extract the lesion point information. The radiation values ​​thus determine the disease type in the SPECT whole-body bone scintigraphy images. However, due to various reasons, the actually obtained bone images are often distorted, and the distorted bone images will lead to inaccurate judgment of the disease type, so it is quite necessary to correct the distorted bone images. However, in the prior art, there is a lack of methods for effectively correcting distorted bone images. [0003] Therefore, there is an urgent need in the art for an accurate technical solution for correcting distorted bone images. Co...
