A medical laser probe to be used as a laser irradiation unit in laser treatment that is performed by irradiating a living body with laser light. The laser probe irradiates laser light uniformly, utilizing laser light effectively by concentration thereof, achieving limited irradiation of laser light and taking countermeasures against stains forming on the probe. The laser probe is provided with (1) a transparent light diffuser for radiating laser light received by a light-guide fiber in the direction along the longitudinal axis of the light diffuser and in radial directions from this axis to the peripheral side surface thereof and (2) a detachable protective diffusion tube for further diffusing laser light radiated from the transparent light diffuser. A reflector may be provided between the light diffuser and the diffusion tube. Further, shielding plates may be provided on the protective diffusion tube.

Laser probe for medical treatment

An apparatus for parallel image generation has four geometric data buffers for storing four partial geometric data, respectively, and four image generators connected respectively to the four geometric data buffers. Each image generator generates a partial image data for every pixel in a frame. Further provided are four image mergers connected respectively to the four image generators. The four image mergers are also connected in series. An initial image generator for generating a background image is connected to the first image merger for merging the background image data and the partial image data from the first image generator. Each of the second to fourth image merger merges an output merged data from the previous image merger and the partial image data from the corresponding image generator. A timing control is connected to the four image mergers for controlling the merging timing in such a manner that the image merger carries out the merging operation of a pixel after the previous image merger has carried out the merging operation of the same pixel.
