Problems solved by technology

Clinically, in order to provide diagnostic basis for relevant patients, formulate reasonable treatment plan, select appropriate treatment method and post-rehabilitation training plan for foot surgeons and brace orthopedic experts, many methods are used in clinical detection of foot arch diseases, but for In the examination of foot and ankle fractures, only different examination methods are proposed for calcaneal fractures, and the research on imaging diagnosis and clinical application of the overall arch curvature of the foot is relatively limited.

Embodiment

[0021] A method for reconstructing an arch of foot image model, comprising the following steps:

[0022] S1: Firstly, X-ray plain films and MSCT scans are carried out to confirm whether they are negative or positive. During the scan, the patient adopts a conforming position and performs a volume scan, so as not to affect the examination due to the limitation of the injured position;

[0023] S2: For positive patients, MSCT scanning was performed, including the lower 1 / 3 of the tibia and fibula and extending to the whole foot, and the original tomographic images were obtained, and a series of post-processing reconstructions were performed;

[0024] S3: Full-length CT scan of the ankle and 3D modeling;

[0025] S4: MPR, MIP, SSD and 3DVR reconstruction are used to obtain image anatomical models of foot bones, muscles, tendons and ligaments respectively; sub-plantar reconstruction is performed, and a plantar longitudinal arch is reconstructed along the long axis of each metatarsa...

Abstract

The invention relates to the technical field of arch model reconstruction, and discloses an arch image model reconstruction method, which comprises X-ray plain film, MSCT scanning inspection, MSCT scanning, MPR, MIP, SSD and 3D VR reconstruction. According to the invention, multi-angle and multi-azimuth reconstruction imaging is carried out by combining an X-ray plain film with various inspectionmeans such as MSCT scanning, MPR, MIP, SSD and 3D VR reconstruction; the goal of comprehensively judging the foot muscle, tendon and ligament damage conditions of the patient is achieved; a static living body arch model obtained through three-dimensional imaging can be rotated by any angle, plantar column two-dimensional imaging is carried out to obtain static, simple, clear and visible arch imagedata and accurate arch evaluation data, and various reconstruction methods are combined to obtain 3D images of full-foot skeletons, muscles, tendons and ligaments.

Description

technical field [0001] The invention relates to the technical field of foot arch model reconstruction, in particular to a foot arch image model reconstruction method. Background technique [0002] The arch of the foot is an important part of the human body when standing upright, walking and bearing weight. Its elasticity can buffer the shock caused by the ground facing the body, and at the same time protect the plantar blood vessels and nerves from compression. The arch of the foot is formed by connecting the tarsal bone and the metatarsal bone through ligaments and joints. The arch of the foot can be divided into inner, outer longitudinal and transverse arches. The medial longitudinal arch is higher and is composed of the calcaneus, talus, navicular bone, 1st to 3rd cuneiform bones, 1st to 3rd metatarsal bones and their connections. It is mainly composed of the posterior tibial tendon, flexor digitorum longus tendon, and quadratus plantar muscle , plantar aponeurosis and c...
