Drug discovery is an interdisciplinary field, focusing on the identification and preclinical testing of candidate drugs in vitro, ex vitro and in vivo. The research and development of new drugs is divided into two stages: research and development. These two stages occur successively and are interrelated. The mark that distinguishes the two stages is the determination of candidate drugs, that is, the research stage is before the determination of candidate drugs, and the work after the determination is the development stage. In recent years, imaging technology has been used in the process of drug research and development, which has greatly promoted the development of the medical field. https://www.bioimagingtech.com/imaging-analysis-for-drug-discovery-development.html
