Description

technical field

[0001] The invention relates to the technical fields of computer graphics and pattern recognition, in particular to a method for performing three-dimensional visualization of ultra-large-scale medical images by using point reconstruction. Background technique

[0002] Since the invention of X-rays, modern medical imaging equipment such as CT (Computed Tomography), MRI (Magnetic Resonance Imaging), CR (Computer X-ray Imaging), B-ultrasound, and electronic endoscope have appeared one after another, making traditional medical diagnosis methods appear. a revolutionary change. With the development of modern computer science and technology, medical image processing has emerged as a new interdisciplinary subject, bringing a new dawn to medical diagnosis. However, the traditional way of viewing films is two-dimensional, requiring trained radiologists to view films and make judgments. With the development of computer visualization technology, three-dimensional visual...

Embodiment

[0070] We apply this method to our self-designed 3D medical image processing and analysis system. The microcomputer-based 3D medical image processing and analysis system 3DMed developed by us is implemented in the computer Windows XP / 2000 / NT / 98 environment, adopts object-oriented design methods and software engineering specifications, and is implemented in C++ language and is oriented to the medical field. 3D image processing and analysis system. This system has rich graphics and image processing and analysis functions, not only has perfect two-dimensional image processing and analysis functions, but also has powerful three-dimensional processing and analysis, network transmission and storage functions. The functions provided by the system include a series of functions such as data input, image data management, 2D processing, 3D data processing, slice reorganization, 3D display, surgical simulation, virtual endoscopy, PACS (image archiving and communication system) and remote ...
