Outcome After Cardiac Arrest in DogsEditorial Comment Treatment With the Competitive NMDA Antagonist GPI 3000 Does Not Improve

A laser light source (110) emits a light that is a laser light. A projection control unit (120) controls, on the basis of image information, the intensity distribution of a light to be projected, thereby generating an image. A projection unit (130) projects the light as controlled by the projection control unit (120). A measurement unit (140) measures the intensity of the light projected from the projection unit (130). A distribution calculation unit (150) calculates, on the basis of the image information, the intensity distribution of the light to be projected from the projection unit (130). A selection unit (160) selects that partial evaluation area of the image which is to be used for determination. A determination unit (170) determines, on the basis of both the light intensity distribution, in the evaluation area, calculated by the distribution calculation unit (150) and the light intensity, in the evaluation area, measured by the measurement unit (140), whether any abnormal projection has occurred. An output control unit (180) controls, on the basis of a determination result of the determination unit (170), either the laser light source (110) or the projection control unit (120).
