Abstract: According to some aspects, a medical imaging system is provided. The medical imaging system includes an illumination device and a medical imaging device. The illumination device includes a first light source configured to emit first light having a wavelength range. The illumination device further includes a second light source configured to emit second light having at least one predetermined wavelength band. The at least one predetermined wavelength band is within the wavelength range. The illumination device further includes a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated. The light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site. The medical imaging device includes at least one sensor configured to receive light from the observation site.

Abstract: The present invention provides a light irradiation method using a pulse laser, which can be applied to technology of PDD and/or PDT, and a system for treating a tumor, which has an enhanced tumoricidal effect. A light irradiation method of irradiating a cell into which a photosensitive compound capable of generating singlet oxygen has been incorporated with a pulse laser having a wavelength within a Soret band is provided. The pulse width of the pulse laser can be set to 100 psec or less, and the wavelength can be set to 405±10 nm. As the photosensitive compound capable of generating singlet oxygen, an agent for photodynamic therapy (PDT) or an agent for photodynamic diagnosis (PDD) can be used.
