Embodiment 1

[0023] Adopt a reference frame for infrared tracking, a screen resolution not lower than 800X600, support multi-touch and handwriting input, support Wi-Fi wireless connection, a tablet computer with a battery life of not less than 8 hours and improvements The surgical navigation system excelim-04 or a higher version navigator composed of a host computer, an infrared locator and related peripheral equipment constitute the surgical navigation and augmented reality system of the present invention. Used to achieve medical augmented reality effects during surgery.

[0024] The host computer performs optical tracking with the help of infrared locator and reference frame to ensure the registration of virtual space and real space. Among them, the tracking adopts the singular value decomposition method to realize the registration of the virtual reality space and the real-time surgical patient space.

Abstract

The invention belongs to the field of medical instruments, and relates to a surgical navigation and augmented reality technology, in particular to a surgical navigation and augmented reality technology based on a tablet computer, wherein the technology is applicable to surgical navigation and reality augmentation for various neurosurgeries. A system comprises the tablet computer and an improved surgical navigation system excelim-04 or a navigator with a higher version, the tablet computer is provided with a reference frame for infrared tracking, the resolution ratio of a screen of the tablet computer is not lower than 800*600, the tablet computer supports multipoint touch, handwriting input and a Wi-Fi (wireless fidelity) connection mode, and the electric endurance of the tablet computer is not lower than eight hours. The tablet computer and the navigator are in real-time communication through Wi-Fi wireless connection, data of the navigator are transmitted to the tablet computer, virtual images and real-time true images of real-time surgical video images shot by the tablet computer are stacked and displayed on the screen of the tablet computer, the real-time surgical video images and preoperative scanned CT (computerized tomography) or MRI (magnetic resonance imaging) data can be completely integrated, surgical efficiency and accuracy are improved, and the technology can be widely applied to surgical navigation for various neurosurgeries.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to surgical navigation and augmented reality technology, in particular to a tablet computer-based surgical navigation and augmented reality system, which is applicable to various types of neurosurgery navigation and reality augmentation. Background technique [0002] Surgical navigation technology originated in clinical neurosurgery. Usually, CT or MRI images of patients are collected before surgery and transferred to an image workstation to form a navigation reference image. When the surgical instrument with a tracer acts on the patient during the operation, the space locator tracks the position of the surgical instrument in the patient's coordinates, converts it into the image coordinate system, and superimposes it with the navigation reference image, just like real-time The same as perspective, so this method is also called "virtual perspective". During the operation, the doctor ca...
