The nine areas of scientific and technological development related to medical imaging and the four areas of application listed above cover a very broad range of imaging modalities.
The invention and development of medical imaging equipment is a revolutionary progress in the diagnosis of human diseases, to promote progress in this area of a number of scientists and therefore get the Nobel Prize, recently got the prize in medicine and physiology is the two medical physics experts are P. C. Lauterbur and P. Mansfield, they are nuclear magnetic **** vibration imaging of the physicists. Depending on the problems that exist in this field now, and the impact that solving them will have on the progress of mankind, more medical physicists will be awarded Nobel Prizes in this field in the future. Therefore, medical imaging physics is a sunrise discipline, and the industry related to this discipline is a sunrise industry.
At present, medical imaging equipment needs to continue to improve the imaging speed, spatial and temporal resolution of the image, and improve the contrast of the image, and the realization of the human body imaging at the molecular and genetic levels has become a new hotspot in the current development. After the publication of the gene sequence, in order to clarify the relationship between genes and biomolecules in the human body, diseases and gene expression and its relationship with biomolecules, the overall level of the human body to carry out gene ligand (through radioactivity) and molecular imaging has become an important direction for the future development of medical imaging. Nuclear medicine imaging has advantages in this regard, the current imaging equipment is mainly single photon tomography (SPECT) and positron tomography (PET), but due to the poor spatial resolution and by the limitations of the radiolabeled drugs, in order to achieve this goal need to do a lot of improvement work on the equipment. Nuclear medicine imaging will receive increasing attention in the future.
