PHOTODYNAMIC THERAPY APPARATUS, METHOD FOR CONTROLLING PHOTODYNAMIC THERAPY APPARATUS, AND PHOTODYNAMIC THERAPY METHOD

摘要

The invention provides PDT equipment which can absolutely treat the deep lesioned part with preserving the superficial membrane of the healthy region.;Photodynamic therapy equipment 1 for treating lesioned part by using a photosensitive substance, which is activated by the light having a peak intensity of a predetermined range but is almost not activated by the light having the peak intensity out of the predetermined range, equipped with an irradiation means 13 irradiating into the body a pulsed light of the wavelength having the potential for activating the photosensitive substance, and a control means 22 controlling the peak intensity of the light irradiated by the irradiation means, and the control means 22 allows the irradiation means 13 to irradiate the light having the high peak intensity in order that the light arriving at the deep-lying lesioned part 41 is to achieve the peak intensity of the predetermined range.
