Abstract

The invention relates to a medical apparatus, a therapy apparatus, a method of estimating an optical probe, and a calibration method. According to an embodiment of the present application, the medical apparatus is provided, including: a light source unit configured to be capable of emitting light including at least natural emission light, the light being guided into an optical probe; a first detecting unit configured to detect an intensity of light exiting from the light source unit; and a calculation unit configured to calculate to approximate to a non-linear function based on an intensity of light detected by the first detecting unit for calibration of the optical probe.

Description

technical field [0001] The present disclosure relates to medical devices, therapeutic devices, methods of evaluating optical probes, and calibration methods, eg for use in therapy with photodynamic therapy and monitoring drug concentrations. Background technique [0002] Basic inspections of medical laser devices began in the 1960s. Then, in the 1970s, using CO 2 Laser therapy devices such as lasers, ND:YAG lasers, Ar ion lasers, and ruby ​​lasers have been developed and widely used. Devices having semiconductor lasers as light sources are being developed as next-generation devices. Semiconductor lasers can be miniaturized, stored easily, and handled easily. Photodynamic therapy (PDT) has attracted attention in recent years as laser technology is developed and as pharmaceutical research is developed. In photodynamic therapy (PDT), laser-sensitive fluorescent drugs accumulate in specific cells. Afterwards, the cell is irradiated with laser light, and the inside of the ce...
