X-ray human body clairvoyance image automatic anastomosing and splicing method

Abstract

The invention relates to the technical field of medical image, in particular to an X-ray perspective human body image montage method. The auto-fusion montage method of the X-ray perspective human body image comprises the following steps: (1) the image is inputted; (2) the human body part is identified intelligently; (3) the translating quantity estimation with multiple dimensions from coarse to accuracy is carried out; (4) the grey scale fusion and montage is carried out; (5) the process is finished. The invention is provided with the function of full-automatic human body X-ray image montage without cockamaie interaction, thus improving the working efficiency of the doctor largely and enabling the doctor to be more concentrated on the profession diagnose. The invention is on the basic of the intelligent analysis and process without depending on the limitation of the imaging hardware system completely, which has more extensive adaptability. As adopting the placement matching algorism and the image pre-processing, the montage reliability is high. As adopting the translating quantity estimating method with multiple dimension from coarse to accuracy, the processing speed is largely improved, and the real-time demand for medical utility is satisfied completely.

Description

technical field

[0001] The invention relates to the technical field of medical imaging, in particular to an X-ray perspective human body image splicing method. Background technique

[0002] For the application of some X-ray medical images, especially for orthopedics, doctors often need to obtain a complete X-ray image of the upper and lower limbs of the patient, or a complete spine image, or even a complete human body image, and because the X-ray photography system Due to the limited size of the imaging device, we can only divide a large object into several shots, and stitching multiple images into a complete seamless image is essential in post-processing. There are the following technical difficulties: ①Since the imaging of the X-ray imaging system is perspective imaging in essence, each pixel point is theoretically the integral of the image of the linear trajectory of the X-ray through the entire thickness direction. For a thick human body, different The projection angle ...
