How far is video film to be history?
Medical imaging and medical film were once inseparable. However, everything has happened, developed, and withered and disappeared. Since the popularization of digital imaging in the 1980s, especially CT technology, the inseparable nature of medical imaging and medical film has been broken. Digital images first exist in storage media such as disks and can be retrieved and shared at any time. In particular, the development and popularization of PACS systems have made imaging experts' imaging diagnosis and browsing more accustomed to soft reading, so that medical film as a diagnostic basis based on this original common sense concept has become a false proposition. At present, as long as a small-scale hospital in the world, medical imaging diagnosis is based on the soft reading of the digital image itself.
Medical film is no longer the basis for imaging diagnosis. Another important reason is that with the rapid development of large medical equipment such as CT, MR, PET-CT, the number of images per patient for imaging examinations is thousands of. It has not been possible to express it with medical film. The post-processing techniques such as 3D reconstruction tend to provide a realistic and vivid stereoscopic image that can be cut and peeled off at any time. These phenomena and the way the clinician's soft reading work makes the plastic film not exist in the medical process. . Moreover, the production and degradation process of plastic film consumes a lot of environmental resources.
However, even if the use of plastic film in Europe and the United States drops sharply, the film usage in China is still growing in 2014. Not only that, at the end of 2014, many imaging experts in China even held academic seminars in Beijing to demonstrate the clinical value of thin film and paper film. In July 2015, the State Food and Drug Administration (SFDA) also issued a paper on the clinical application of medical thermal film and paper film.
It is undeniable that the benefits of the medical film supply chain are huge. In 2014, the size of China's medical film market reached more than 12 billion. Traditional film suppliers will naturally try to maintain rich commercial interests. We look back at the inventor of the digital camera: Kodak Company of the United States, in a board vote on the direction of the company in the 1990s, shareholders representing the interests of film defeated the shares representing digital technology, and the end result is what we see today, the United States. Kodak has become a memory that humanity has ended.
The team does not do the mode, the mode does not trend. In the Internet+ era, everything that does not belong to the Internet, the habits, cultures, methods, media, individuals, and communities that are hedged, limited, and inconvenient to share with the Internet will eventually be marginalized and dying out. Film images are limited to physical media, which is inconvenient to share and deplete human precious resources. Elimination is inevitable. Not only that, but physical media such as CDs and USB flash drives will also be eliminated by cloud storage and network ecosystem.
