Surgical microimaging system based on optical coherence tomography augmented reality

Abstract

The invention discloses a surgical microimaging system and method based on optical coherence tomography augmented reality. The system comprises a surgical microscopic unit which is used for collectingtwo-dimensional microscopic images of a surgical region, an optical coherence tomography unit which is used for collecting OCT three-dimensional images of the surgical region, a guiding light sourcewhich can be captured by a camera of the surgical microscopic unit and is used for projecting a guiding light spot synchronized with an OCT scanning light source of the optical coherence tomography unit, a processing control unit which is used for acquiring the two-dimensional microscopic images and OCT three-dimensional images of the surgical region, as well as images after the two-dimensional microscopic images and the OCT three-dimensional images of the surgical region are fused, and a display unit which is used for outputting and displaying results of the control unit. The surgical microimaging system can be used for accurately registering and fusing two-dimensional microscopic images and OCT three-dimensional images, realizes microscopic image real-time augmentation of microscopic images of the surgical region, provides intuitive navigation information to surgery, and realizes intuitive surgical guidance.

Description

technical field [0001] The invention relates to the technical field of microsurgery imaging and graphic processing, in particular to a surgical microscopic imaging system based on optical coherence tomography augmented reality. Background technique [0002] Modern surgery has required that while locating the surgical target site, the physiological creation of the patient should be reduced as much as possible to achieve minimally invasive surgery. Image-guided interventional surgery can accurately locate the surgical target, can carry out preoperative planning before surgery, real-time monitoring and navigation during surgery, and evaluation of surgical effects in the surgical area after surgery. It has the advantages of high precision and small trauma. , is an important direction of modern surgery. [0003] At present, the imaging range of optical microscope-based microsurgery, such as ophthalmic surgery and neurosurgery, is limited to two-dimensional imaging of the surface...

Problems solved by technology

The key to augmented reality technology lies in virtual-real registration, that is, to establish the coordinate transformation relationship between virtual images and real scenes. Registration as a reference point can get a matching result with better accuracy, but this method may be traumatic; using body surface features to set a reference point can avoid additional trauma, but the recognition effect is not good when the features are not obvious, limiting application of the method
