Patent ID: 8868160

Claim:
A medical apparatus comprising: a storing section configured to store a drug kinetics in a living body in advance for each of plural kinds of fluorescent drugs; a processing section configured to acquire diagnosis start time based on the drug kinetics stored in the storing section, a target region of an object to be examined to which a desired fluorescent drug is administered, a method of administering the desired fluorescent drug to the target region, and administration start time of the desired fluorescent drug, the diagnosis start time being a first time when an accumulation amount of the desired fluorescent drug administered to the target region reaches a predetermined reference value after the administration start time; a determining section configured to determine whether present time reaches the diagnosis start time, based on the diagnosis start time acquired by the processing section; and a light source control section configured to perform control to a stop radiation of excitation light for exciting the desired fluorescent drug when the determining section determines that the present time does not reach the diagnosis start time and perform control to radiate the excitation light when the determining section determines that the present time reaches the diagnosis start time.
