Percutaneous aortic valve replacement (TAVI) has been clinically applied since the beginning of this century and after more than 10 years of research and therapeutic practice, it is now incorporated into the standard treatment protocol, and more than 200,000 people have been treated with TAVI in 65 countries worldwide.TAVI is aimed at patients with aortic valve stenosis, and this treatment is generally used for two One is that his disease is too severe to do surgery; the other is that surgery is possible, but the risk level of surgery is very high. TAVI is also very effective and has been shown to reduce the mortality rate by about 50% within one year. For high-risk patients, complications such as stroke are also very rare. 3D printing is a synonym for cutting-edge technology, involving information technology, materials science, precision mechanics and many other aspects. The main feature of this technology is that products of various shapes can be generated directly from computer graphics data by means of additive manufacturing. Nowadays, the development of 3D technology involves various industries. Especially in the medical industry, the impact of “3D printing technology” is becoming more and more prominent. For example, printing three-dimensional portraits and teaching aids, or printing dentures and bone and joint replacements, etc. 3D printing has a wide range of applications in the medical field. These two technologies are currently at the forefront of clinical medical development, and both are closely linked to CT image-guided treatment, especially reflecting the global advocacy of the concept of “precision medicine”, in other words, how more accurate, precise and safe implementation of these clinical treatment means, depends entirely on the acquisition of ultra-high resolution CT data! So let’s get to the point: this year’s Siemens CT showed the world dazzling CT images for the first time at the RSNA show! Awesome, right? At first glance, I thought it was a partial anatomy of a real human body, once again, the guys were stunned, is this the image that CT can scan out? Yes, this is what SOMATOM Force Open Source CT will bring us in the future: the technology that so realistically and faithfully reproduces the anatomy of human organs is the Quantum Optical Imaging method, which is called the “Holy Grail” of CT imaging, breaking through the pure geometric simulation modeling method of traditional CT to simulate the complex interaction between photons and the patient’s scanned It is a breakthrough from the purely geometric simulation of traditional CT modeling to simulate the complex interaction between photons and the tissue being scanned to produce realistic images and videos. This new generation of medical research imaging technology will facilitate research and create new ways of medical education and patient communication.
