<p>PURPOSE:To obtain a scintillation camera which can reduce a reference light source for correction and further improve correction reliability. CONSTITUTION:A scintillation camera comprises at least ten photoelectron multipliers 41 to 410 and at least three periodically illuminated reference light sources 5A to 5C, while the multipliers and the light sources are arranged in an equal direction. Nine of the photoelectron multipliers 41 to 410 (except a photoelectron multiplier 46) are arranged adjacently together with the three reference light sources 5A to 5C, while the remaining one photoelectron multiplier 46 is separated by an equal distance from the three reference light sources 5A to 5C.</p> |
