Three-dimensional reconstruction examination is the effect of reorganizing the standing body through computer processing, which helps in diagnosis and treatment. Three-dimensional reconstruction is to transform the traditional two-dimensional image into three-dimensional rotatable image information through digital signal processing. Through the three-dimensional reconstruction technology, the lesion and spatial location, size, shape of the examination site and the spatial relationship between the surrounding organs, blood vessels and lymphatic vessels can be determined. With the development of modern medical technology, this technology is widely used. Especially for patients with vascular lesions, neuropathy and tumor lesions, this technology can help doctors understand the patient’s condition to a large extent, so that doctors can better take corresponding treatment measures to help patients recover. If 3D reconstruction is needed in the clinic, it is recommended to do this examination under the operation of a professional doctor.
