Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them.

[0027] A double lower limb scanning method for assessing line of force before knee arthroplasty, comprising the following steps:

[0028] S01: The patient lies supine on the CT scanning bed, keeping the midline of the body consistent with the midline of the scanning bed;

[0029] S02: CT scans the upper and lower sides of the hip joint of the patient's lower limbs;

[0030] S03: CT scans the upper and lower sides of the knee joint of the patient's lower limbs in two segments;

[0031] S04: CT scans the upper and lower sides of the ankle joint of the patient's lower limbs in three segments;

[0032] S05: Import the three sets of scanning CT data packets into the processing system to obtain CT scanning medical images.

[0033] The scannin...

Abstract

The invention discloses a double-lower-limb scanning method for evaluating a force line before knee replacement, which comprises the following steps: S01, a patient lies on the back on a CT (Computed Tomography) scanning bed, and the center line of the body is kept consistent with the center line of the scanning bed; s02, performing one-section scanning on the upper and lower sides of the hip joint of the lower limb of the patient by CT; s03, performing two-section scanning on the upper and lower sides of the knee joint of the lower limb of the patient by CT; s04, performing three-section scanning on the upper side and the lower side of the ankle joint of the lower limb of the patient by CT; s05, the three groups of scanning CT data packets are imported into a processing system, and CT scanning medical images are obtained.According to the scanning method, the mode that the two lower limbs are scanned in three sections is adopted, the radiation influence on the patient in the process of scanning the two lower limbs can be reduced, meanwhile, a large amount of unnecessary section data existing in full-section scanning of the two lower limbs can be avoided, and the scanning efficiency is improved. The method can play a good role in assisting preoperative data in the HTO operation, has a good evaluation effect on the HTO preoperative, and has a great popularization value.

Description

technical field [0001] The invention relates to the technical field of CT scanning, in particular to a double lower limb scanning method for force line assessment before knee joint replacement. Background technique [0002] High tibial osteotomy (HTO) is an important surgical method in the stepwise treatment of knee arthritis, and its postoperative efficacy has been recognized. The purpose of the operation is to correct the alignment, reduce the pressure of the diseased compartment, and finally correct the joint deformity , to relieve knee joint pain, delay disease progression, and regenerate cartilage. In order to help surgical medical staff fully and accurately understand the detailed information of the patient's lower limbs, it is necessary to use a CT scanning table to scan the patient's lower limbs to obtain corresponding medical images. [0003] Chinese patent CN107468268A discloses "medium-pitch single scan two-way CT lower extremity venography method", including step...
