摘要：
[Object] To provide a calculation apparatus and a calculation method capable of calculating pharmaceutical concentration in a tissue in real time.[Solving Means] A photodynamic therapy apparatus as a calculation apparatus is an apparatus for irradiating a tissue having absorbed photo-sensitive pharmaceutical, the photo-sensitive pharmaceutical absorbing an excitation light and emitting fluorescence, with the excitation light emitted from a tip portion of a laser catheter, including a connector, a light source, and a light detection unit. The laser catheter is capable of being attached/detached to/from the connector. The light source outputs the excitation light to the laser catheter via the connector. The light detection unit detects intensity of the fluorescence, the fluorescence being entered from the laser catheter via the connector, to calculate concentration of the photo-sensitive pharmaceutical in a tissue, the tip portion of the laser catheter contacting the tissue.
