Abstract
A tumor treatment apparatus is provided including a light source which emits a bundle of light including ultraviolet radiation, visible radiation and infrared radiation. Also provided are an infrared radiation filter which filters infrared radiation, a visible radiation filter which filters visible radiation, and an optical fiber which transmits a bundle of light transmitted through the infrared radiation filter and the visible radiation filter toward an affected part of a patient to be treated.
Claims29
A tumor treatment apparatus for treating an affected area, said tumor treatment apparatus comprising:
- a light source which emits a beam of light including ultraviolet radiation, visible radiation and infrared radiation;
- an infrared radiation filter for filtering infrared radiation;
- a visible radiation filter for filtering visible radiation, said visible radiation filter filtering only a predetermined portion of the visible radiation emitted by said light source;
- and
- a system that transmits a beam of light including ultraviolet radiation and filtered visible radiation, transmitted through said infrared radiation filter and said visible radiation filter, to radiate said beam of light including ultraviolet radiation and filtered visible radiation onto an affected area to be treated.
A tumor treatment apparatus comprising:
- a light source which emits a beam of light including ultraviolet radiation, visible radiation, and infrared radiation;
- an infrared radiation filter that filters infrared radiation;
- a visible radiation filter that filters visible radiation;
- a light transmitting system that transmits a beam of light comprising ultraviolet and visible radiation, transmitted through said infrared radiation filter and said visible radiation filter, so that said beam of light comprising ultraviolet radiation is incident onto an affected area to be treated;
- and
- a positioning system that selectively positions said visible radiation filter in and out of said beam of light, whereby the beam of light transmitted through said light positioning system can include ultraviolet radiation and unfiltered visible radiation or can include ultraviolet radiation and filtered visible radiation.
A tumor treatment apparatus which emits light of a continuous spectrum including an ultraviolet spectrum, a visible spectrum and an infrared spectrum, said light being emitted from a light source lamp, said tumor treatment apparatus adapted for emitting light of the continuous spectrum onto an area of tissue of a living body in which TiO.sub.2 has been administered, said light being transmitted through an optical fiber through which ultraviolet light can be transmitted, said tumor treatment apparatus comprising:
- an infrared radiation filter for filtering infrared light of said light emitted from said light source lamp before said light is made incident upon said optical fiber;
- and,
- a visible radiation filter for filtering only a predetermined portion of visible light having a wavelength that is around 400 nm to 700 nm emitted from said light source lamp before said light is made incident upon said optical fiber.
A tumor treatment apparatus comprising:
- a light source which emits a beam of light including ultraviolet radiation, visible radiation and infrared radiation;
- an infrared radiation filter that filters infrared radiation;
- a visible radiation filter that filters visible radiation, said visible radiation filter filtering only a portion of the visible radiation emitted by said light source;
- a light transmitting system that transmits a beam of light consisting of ultraviolet radiation and filtered visible radiation, transmitted through said infrared radiation filter and said visible radiation filter, so that said beam of light consisting of ultraviolet radiation and filtered visible radiation is incident onto an affected area to be treated;
- and
- a positioning system that selectively positions said visible radiation filter in and out of the beam of light.
