Problems solved by technology

The degree of completion of traditional manual acupuncture surgery depends on the doctor's professional quality and operating experience, and the accuracy of the operation is low.
Although the particle implantation robot improves the accuracy of the operation, the structure of the robot is exquisite and complicated, and the equipment cost is high
3D printing templates for particle implantation can reduce operation time and improve surgical accuracy, but when the patient's anatomical structure changes, it is difficult to adjust the treatment plan due to the long cycle required for printing 3D templates

Embodiment 1

[0016] Embodiment 1 of a camera-based image-guided particle implantation system includes CT imaging equipment, a planning system workstation, an arc-shaped pressing plate 104 with reflective balls 106 installed, a positioning rod 102 with reflective balls 105 installed, and a camera real-time positioning device 103. The planning system workstation includes a computer and particle implantation planning system software running on the computer.

[0017] The CT imaging equipment saves the scanned CT images as files in DICOM format, and the user copies these CT image files to the planning system workstation, and the particle implantation planning system software reads them in. The particle implantation planning software can display the cross section, coronal plane, sagittal plane and oblique plane at any angle of the anatomical image, and the user can outline the tumor and surrounding important organs on each of the above display surfaces; similarly, it can also be displayed on eac...

Embodiment 2

[0025] Embodiment 2 of a camera-based image-guided particle implantation system includes a PET-CT imaging device, a planning system workstation, a positioning sticker 204 , a fluorescent positioning stick 202 , and a camera real-time positioning device 203 . The planning system workstation includes a computer and particle implantation planning system software running on the computer.

[0026] The PET-CT imaging equipment sends the scanned PET image and CT image to the DICOM server through the network, and the particle implantation planning system software queries and reads the PET image and CT image data from the server through the DICOM network protocol. The particle implantation planning software can display the cross-section, coronal plane, sagittal plane and oblique plane at any angle of CT images, PET images or both fusion images, and users can outline tumors and surrounding important organs on the above-mentioned display surfaces; Alternatively, needle tracks for particl...

Abstract

The invention discloses an image guided seed implantation system based on a camera. The image guided seed implantation system comprises imaging equipment, a plan system workstation, a patient positioning marker, a positioning marker mounted on a seed implantation device and a camera real-time positioning device. The camera real-time positioning device calculates spatial coordinates of the positioning marker through binocular vision principles and displays three-dimensional images of tumor, a region of interest, a planned needle passage and a real-time needle passage in a plan system. The image guided seed implantation system brings convenience to a doctor to accurately implement and adjust plans.

Description

technical field [0001] The present invention relates to an image-guided particle implantation device. Background technique [0002] At present, the radiotherapy technology of implanting particles into the human body to treat tumors has been widely used clinically. The degree of completion of traditional manual acupuncture surgery depends on the doctor's professional quality and operating experience, and the accuracy of the operation is low. Although the particle implantation robot has improved the accuracy of the operation, the structure of the robot is exquisite and complicated, and the equipment cost is high. 3D printing templates for particle implantation can reduce surgical time and improve surgical accuracy, but when the patient's anatomical structure changes, it is difficult to adjust the treatment plan due to the long cycle required to print 3D templates. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a came...
