Abstract

The invention relates to a method and device for automatically extracting lower limb femur and tibia axes and electronic equipment. The method comprises the steps that a full-length load original graph of the two lower limbs is obtained; obtaining a target image according to the double-lower-limb full-length load-bearing original image; based on a preset interception rule, intercepting a femur region image and a tibia region image from the target image; based on a preset first determination rule, determining a thighbone axis according to the thighbone region image; based on a preset second determination rule, determining a tibia axis according to the tibia region image; and marking the femur axis and the tibia axis in the target image based on a preset reduction rule. The method has the effect of quickly and accurately determining the axes of the thighbone and the tibia of the lower limb.

Description

technical field [0001] The present application relates to the field of image processing, and in particular, to a method, a device and an electronic device for automatically extracting the axes of the femur and tibia of a lower extremity. Background technique [0002] The lower limb force line is the axis passing through the hip joint, the center of the knee joint and the center point of the ankle joint. The restoration of the lower limb alignment basically depends on the precise positioning of the femoral axis. In order to better match the femoral prosthesis, the anterior-posterior axis of the distal end of the femur is usually used as a reliable sign of the contralateral rotation of the femoral prosthesis, and furthermore, the accurate positioning of the tibial plateau cutoff is performed. Bone, usually marks the tibial axis, therefore, the determination of the lower extremity femoral and tibial axis is crucial in the measurement of the lower extremity alignment. [0003] ...
