[0017] The present invention will be described in further detail below according to the drawings and specific embodiments.

Description of drawings

[0018] figure 1 Is the working flow diagram of the embodiment of the present invention.

[0019] Such as figure 1 Shown, the automatic extraction method of vertebra in a kind of MRI lumbar vertebra image of the present invention comprises the steps:

[0020] 100: Read the T2DICOM image file of the patient's lumbar spine MRI examination in the specified folder to the memory and normalize the gray value of the image to the range of 0-255;

[0021] 200: Perform Gaussian filtering on the grayscale image and use the CANNY operator to obtain an edge binary image;

[0022] 300: Labeling the binary image and obtaining the position and number of vertebrae according to the shape and grayscale features of the vertebrae and calculating the vertebral feature quantity;

[0023] The DICOM image of the pati...

Abstract

The invention provides an automatic extraction method for the vertebra in MRI lumbar vertebra image. The invention relates to the field of medical image processing technology and more particularly to an automatic extraction method for the vertebra in MRI (Magnetic resonance imaging) lumbar vertebra image. With the progress in medical image technology, MRI has already become an important means for diagnosing lumbar vertebra troubles. Traditionally, it takes about ten minutes to locate a troubled vertebra of a patient through the use of a mouse, which directly influences the working efficiency of a doctor to diagnose. The invention solves the problem of automatic identification and extraction of vertebra in MRI lumbar vertebra image. Through the use of the MRI lumbar vertebra's T2 image, it is possible to automatically extract the vertebra and to automatically calculate the size, the width, the height and the average grayscale of the vertebra so as to realize quantitative diagnosis of vertebra troubles rapidly and to increase the diagnosing efficiency of vertebra diseases.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to an automatic extraction method of vertebrae in MRI (magnetic resonance imaging) lumbar images. Background technique [0002] With the advancement of medical imaging technology, MRI has become an important means of lumbar disease diagnosis. In order to realize the quantitative diagnosis of diseases such as lumbar vertebral slippage and vertebral fracture, it is necessary to accurately segment and identify each vertebral body from the diagnostic image. However, it is far from enough to rely solely on manual methods to complete this work. The traditional assessment of vertebral fractures is to manually mark 6 points (the four corners and the midpoint of the upper and lower edges) for each vertebra, and then measure the heights of the front, middle, and back vertebrae. But this process is quite time-consuming. It takes more than 10 minutes to locate one vertebra o...
