Estimating the term…
A photodynamic therapy apparatus as a determining apparatus is the photodynamic therapy apparatus for irradiating a tissue having absorbed photo-sensitive pharmaceutical, the photo-sensitive pharmaceutical absorbing an excitation light and emitting fluorescence, or a tissue absorbing the 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 or a spectrum of the fluorescence, the fluorescence being entered from the laser catheter via the connector, to determine whether the tip portion of the laser catheter contacts the tissue or not.
A determining apparatus for irradiating a tissue having absorbed photo-sensitive pharmaceutical, the photo-sensitive pharmaceutical absorbing an excitation light and emitting fluorescence, or a tissue absorbing the excitation light and emitting fluorescence, with the excitation light emitted from a tip portion of a laser catheter, comprising:
A determining method, comprising:
A determining method using photo-sensitive pharmaceutical absorbing an excitation light and emitting a fluorescence, a laser catheter capable of emitting the excitation light from a tip portion, and an estimating apparatus including a connector to/from which the laser catheter is capable of being attached/detached and a light source for outputting the excitation light to the laser catheter via the connector, comprising:
