Diagnosis system using fluorescence information and acidity information and diagnosis method using same

A diagnosis system comprising:

• a fluorescence information obtainment part configured to obtain a first fluorescence lifetime information and a first fluorescence intensity information from each of samples and to obtain a second fluorescence lifetime information and a second fluorescence intensity information from a specimen subject to diagnosis;
• an acidity information obtainment part configured to obtain a first acidity information from each of the samples;
• a derivation part configured to derive a correlation between the first fluorescence lifetime information and the first acidity information for each of the samples;
• an acidity information calculation part configured to calculate a second acidity information of the specimen based on the second fluorescence lifetime information obtained from the specimen, using the correlation;
• and
• a diagnostic part configured to perform cancer diagnosis on the specimen based on the second fluorescence lifetime information obtained from the specimen and the calculated second acidity information,
• wherein the acidity information calculation part is configured to obtain the first acidity information from each of the samples, based on the correlation between acidity of fluorescent contrast agent and the first fluorescence lifetime information, wherein the fluorescent contrast agent is used to obtain the first fluorescence lifetime information and the first fluorescence intensity information of each of the samples,
• wherein the acidity information calculation part is configured to calculate the second acidity information of the specimen, using the correlation on the sample corresponding to the specimen among the correlations on each of the samples which are derived by the derivation part,
• wherein the sample is cancer cells of each type that are the target of diagnosis,
• wherein the derivation part is configured to derive the correlation between the first fluorescence lifetime information for each type cancer cell and the first acidity information.
