[Viewpoint] Can future medical black technology replace doctors?
Like the cartoons, the cute "big white" is on the side, guarding your health; some diseases do not need to go to a crowded hospital; even if you travel in space, you can remotely diagnose and treat at any time; during surgery, virtual reality (VR) Technology has "visualized" the most complex human body... With new technologies such as artificial intelligence, robotics, and virtual reality approaching the medical field, these "sci-fi" scenes are no longer illusory. In the future, will "black technology" replace doctors? Can patients not go to the hospital again?
Virtual reality: Can a complex human body be at a glance?
In 2016, the first year of virtual reality technology, virtual reality broke the limitations of individual time and space, and set off an application boom in games, shopping, real estate, tourism and other industries. Can virtual reality technology also give an unobstructed view of the human body?
Not long ago, at the Precision Tumor Surgery Center of Sun Yat-sen Memorial Hospital of Sun Yat-Sen University, doctors used a three-dimensional visualization system to successfully remove a huge hepatoblastoma for a 7-year-old girl.
Because the tumor is closely intertwined with the surrounding organs, the operation is very difficult. "Cut more, the child is likely to have major bleeding, can not get the operating table; cut less, the tumor will recur in a short period of time." Center Deputy Director Chen Yajin said that the existing electronic computed tomography (CT) and nuclear magnetic resonance (MR) scan Technology can only express the anatomical information of a certain interface. Doctors can only "conceive" the three-dimensional geometric relationship between the lesion and its surrounding tissues by multiple two-dimensional images. Holographic projection and virtual reality technology help doctors to completely remove the lesion, and patients get more information from it. Finally, Chen Yajin cut a tumor with a diameter of 15 cm and a weight of 1.4 kg for the girl, and the bleeding was less than 200 ml, achieving precise minimally invasive effects.
At the inaugural meeting of the Virtual Reality Industry Alliance held in Beijing in September this year, Academician Zhao Yuping of the Chinese Academy of Engineering proposed that the virtual human body will become the basis for conducting medical behavior. Given the complexity of the human body, virtual humans should be the ultimate goal of virtual reality.
On November 30th, Guangzhou launched the “Virtual Reality (VR) Hospital Programâ€. According to Zhong Shizhen, the chief scientist of the "Virtual Reality Hospital Program" and academician of the Chinese Academy of Engineering, China's "digital virtual person" will be implemented in three phases: the first stage is high-quality human body geometric image acquisition and computer three-dimensional reconstruction, complete the basic On the basis of morphological geometry and digital virtual people, China has successfully constructed a anatomical virtual human data set for men and women. The second stage is the physical virtual person, that is, the physical information of various tissues of the human body, such as strength and tensile resistance coefficient, is added on the basis of the geometric virtual person. The third stage is the physiological virtual person, which is the ultimate goal of digital virtual human research, which can reflect the regular evolution of growth and development, metabolism, and reproduction of physiological pathology.
