Do you imagine that you have a pair of perspective eyes?
Can you see if someone behind the closed door can see the various components in an electronic product, or can you see the tissues and organs in the human body? I believe that many people want a pair of perspectives, but the earliest possible realization of this "dream" may be doctors.
Recently, the US Food and Drug Administration (FDA) announced that the OpenSight AR system developed by Novarad has become the first FDA-approved medical AR solution for Microsoft HoloLens, which enables 2D, 3D and 4D imaging technologies. The doctor gets a visual guide to the problems that may be encountered during surgery before the surgery begins.
Imagine that when you go to the hospital to see a doctor, the doctor only needs to "see" you up and down to know which organ you have had a problem, and even to judge whether you need surgery. Is this diagnosis reliable?
What is the future of AR medical treatment?
According to Goldman Sachs, the market size of VR and AR will reach 80 billion US dollars by 2025. Among them, the medical health expects users to be about 3.4 million by 2025, and the market size will reach 5.1 billion US dollars. It can be seen that VR and AR medical health still have great potential.
At present, there are many praised products in the field of AR medical treatment. Among them, the most powerful one is the Microsoft HoloLen holographic glasses mentioned above, which can observe the human body structure. In addition, the Philips Healthcare Department has developed with Accenture. An AR application to monitor patient vital signs; a hospital in southeastern India has completed two operations with Google AR glasses; a 3D augmented reality system from game giant Illusion helps doctors better perform cosmetic surgery .
However, AR products that claim to be or have been assisted with surgery are essentially more like an AR "magnifying glass". The method of use is mainly for doctors to see the subtleties that are difficult to distinguish with the naked eye. For truly high-risk, high-precision surgery, whether it is HoloLens or other AR products, it may not be able to meet the clinical needs of the product.
This is because during the operation, the product needs to ensure at least the recognition tracking accuracy within 1mm, but HoloLens or Apple's ARkit are still based on the optical SLAM algorithm for image recognition and tracking. The accuracy of the algorithm can not support the operation level.
This is also the problem of most AR products. Nowadays, most of the AR application image quality effects are inferior. The ordinary patients who are used to high-definition and ultra-clear plane images are still unbearable in these “slag qualityâ€, let alone the image accuracy requirements. Medical industry .
Domestic medical-related AR entrepreneurial projects are also facing such technical problems, limited by algorithms, many products have problems such as low definition and serious loss of details. In addition, many products are still lacking in surgical navigation. Accurate auxiliary space positioning system, the degree of realization of natural gesture interaction is also a technical hurdle.
In addition, if the AR is combined with reality, the product needs to track the patient's action posture, locate the patient's height and body structure based on the posture information, and then accurately display the previously rendered 3D virtual structure ratio on the patient's Physically, the doctor can perform an observation of the internal structure of the patient's body.
Among them, these virtual images are reconstructed according to the patient's real medical image information, such as CT/MIR ultrasound image 3D. So, regardless of whether the data privacy can be secured, the body is “perspective†and the patient can tolerate it. What is the "intrusive feeling" brought by the doctor's sight?
AR can also land like this before starting surgery
1. More popular patients/consumer
Currently, technology companies' VR/AR healthcare products are targeted at hospitals and third-party laboratories, including hardware and PC applications. Obviously, AR medical companies are increasing the development of B-side users, such as pharmaceutical companies and medical equipment manufacturers.
However, when the professionalism and precision can not meet the surgical standards, it is difficult to please the patient and not to be hospitalized. Therefore, before going to the B-end, the C-side is undoubtedly the best "hotbed".
Among them, AR products for women's medical beauty and health have more potential space. According to statistics, 61.7% of the people who are interested in plastic surgery spend more than 5,000 yuan a year on plastic surgery, an increase of 11.7% over the previous year. 18.37% said they accept borrowing and plastic surgery, provided that Good."
And this "premise" can be handed over to the AR to confirm. For example, before breast augmentation surgery, the user wears the device, uses the mobile phone or tablet lens to capture the image of his body curve, and finally submits it to the software for calculation. Then, the breast simulation image of different cups and shapes is projected and superimposed on the user. The degree of 3D image presents a possible physical defense after surgery, and the user can decide whether to accept breast augmentation surgery according to the effect. More than that, AR can also be used for pre-judgment of pre-operative effects such as facial features and facial pulls.
There are also a lot of AR apps dedicated to women's health. Hologic's Hologic Augmented Reality app is designed to interact directly with users and provide a comprehensive imaging system and diagnostic testing products.
Regarding AR products, the future model will be more and more diversified, and the products offered will be more abundant. For example, users can use the accurate images provided by AR medical applications to complete the whole process of self-diagnosis step by step. First-aid personnel use the AR head-mounted display to command on-site personnel to make targeted rescue measures to prevent missed best first aid due to missed rescue time. Wait.
2. AR medical teaching, especially Chinese medicine teaching
The application of AR technology in medical education and teaching has gradually increased. At present, the more mature AR medical teaching is about the illumination of blood vessels. Students can view hidden blood vessels through PC application software. The OpenSight AR system mentioned at the beginning of this article also developed a teaching version of the software that allows doctors to virtually dissect virtual corpses. In this way, it is more intuitive and stereoscopic than traditional wall-mounted anatomy teaching, and is more conducive to students' clinical practice.
In Western medicine, AR products are not too small, but in the field of Chinese medicine education, due to the particularity of the Chinese medicine discipline, there are very few AR applications in teaching methods. However, it is precisely because of the abstraction of Chinese medicine knowledge and the profound esoteric theory that it is more important to pursue innovative teaching methods.
For example, by combining AR technology with Chinese herbal medicine maps, Chinese medicine plants and decoction pieces can be stereoscopically displayed through AR technology; or in the acupuncture teaching process, AR technology presents a virtual human body model for students to demonstrate acupoint positioning. Teaching methods such as needle-in-hand approach.
By using AR technology, the complex data is visualized by computer, and the students are provided with a scene combining virtual environment and real world, so that students are immersed in the scene of augmented reality and passively accepted as active learning.
There are now teaching aids that combine medicine and AR mobile phone applications, such as Aug-ment 3D and AR Chinese herbal medicines. The latter can realize the high-precision rendering of Chinese herbal medicine 3D by using the AR scanning picture function. The former not only has a rich 3D model library, but also provides an interface to the 3D model. Users can add 3D model diagrams or 3D animation models to the model library.
in conclusion:
With the development of AR/VR, artificial intelligence and other technologies, AR technology will be better applied in remote consultation, ward care, rehabilitation and other aspects, and will more generally benefit the consumer. It is believed that in the near future, AR technology will continue to develop and progress, bringing new breakthroughs in the medical field.
Probiotics are a kind of active microorganisms that are beneficial to the host by colonizing in the human body and changing the composition of the flora in a certain part of the host. By regulating the host mucosa and the immune function of the system or by regulating the balance of intestinal flora, promoting the absorption of nutrients to maintain intestinal health, thus producing single microorganisms or a well-defined mix of microorganisms that are conducive to health effects.
Probiotics Powder has many benefits. It's a Nutritional Supplements.
Probiotics can synthesize digestive enzymes. Together with the digestive enzymes synthesized by animals, they participate in the digestion of nutrients in the intestine, stimulate the secretion of digestive enzymes in the animal body, reduce the depth of small intestine recess, increase the villi height, increase the surface area of the small intestine, and promote the absorption of intestinal nutrients. Probiotics can also be used as Food Additives.
Probiotics' own structure, such as peptidoglycan, lipoteichoic acid and other components, can act as antigens to directly activate the immune system, or stimulate the host immune system through autocrine immune activators, thereby improving the immunity of animals, enhancing the activity of the body's innate immune cells and natural killer cells, activating dendritic cells, and stimulating the body to produce cytokines. And stimulate B cells to secrete antibodies, probiotics can stimulate the gut to produce secretory globulin A (SIgA), protect body health.
