Although advanced surgical methods have limitations compared to traditional surgical methods, fortunately, these problems can now be overcome by using virtual reality techniques. No one can question the significance of VR for medical care. Whether it is surgery, psychotherapy or rehabilitation training, VR offers a whole new treatment. Not only hospitals, major technology giants have also paid attention to this area. In October of this year, Intel invested in EchoPixel, a VR medical company, to provide clinicians with VR technology for diagnosis and surgery so that doctors can observe and interact with specific sites. HTC also invested in VR Medical Surgical as early as last year. The company's technology can provide VR-impact navigation during surgery and improve doctors' surgical methods. The latest report from Kalorama Information, a foreign medical market research agency, predicts that the virtual reality and augmented reality markets in the US medical sector (surgery, medical education and training, pain clinics, and rehabilitation) will approach $1 billion in the next few years. From a professional perspective, VR's help with medical surgery is mainly reflected in the following aspects: • When performing laparoscopy and endoscopy, doctors cannot see the affected area directly as in traditional open surgery. Micro-injury and reliance on endoscopic/laparoscopic observations limit the doctor's vision and prevent doctors from fully viewing the body's internal conditions. • Surgical navigation systems or image-guided surgery (IGS) systems have begun to use virtual models to navigate and guide surgery, although in some cases they are limited by the lack of resolution in the virtual environment or by reference parameters, presenting two-dimensional images and Lack of segmentation. • There have been problems with robot-assisted surgery when it comes to laparoscopy/endoscopy and IGS systems, such as limited reference vision frames for surgical sites or insufficient resolution for precision navigation. • The accuracy of radiation therapy has improved over the past few decades. The most recent systems are intensity modulation (IMRT) and image-guided radiation therapy (IGRT) systems that use image-guided and complex transmission models. These systems attempt to provide the most dose within the tumor target while minimizing the impact of radiation therapy on the healthy tissue surrounding the diseased site by accurately aligning the affected site and tracking relative to a simulated or therapeutic model. Virtual Reality (VR) and Augmented Reality (AR) technologies have been introduced into surgical navigation, RAS, and radiation therapy. The most common is to use preoperative and intraoperative medical imaging to construct a simulation or model of a patient's anatomy and then use it for navigation of surgical instruments, intraoperative segmentation, labeling of key anatomies, or targeted delivery of radiation. Many surgical navigation, RAS, and radiotherapy equipment vendors are not yet familiar with AR/VR technology. These manufacturers have not yet incorporated VR/AR heads or their immersive systems into their systems. Despite this, many surgical platforms already have VR and AR technology capabilities and are injecting AR images and more interactive and immersive virtual models.
