FIELD: medical engineering.
SUBSTANCE: device has laser mounted on its optical axis and fixed diffusely scattering screen. An additional non-transparent screen has slits and zones transparent for radiation to pass. The additional screen is placed behind the diffusely scattering screen. One or several reflectors having curved reflecting surface are placed between the laser and diffusely scattering screen. The reflectors are movable relative to laser radiation beam to enable laser radiation beam to be directed to the reflecting surface of at least one reflector at any time moment.
EFFECT: enhanced effectiveness of diagnosis and treatment procedures.
