Stabilized pulsed laser apparatus including pulsed laser means providing an output beam including a plurality of pulses, a pulse controller providing control instructions to the laser, and an attenuator for selectably performing attenuation of the output beam of the pulsed laser means in response to at least the time interval between a given pulse and the pulse preceding it, for maintaining at least one desired energy characteristic notwithstanding changes in at least the time interval.

A gamma camera comprises a scintillation crystal having an index of refraction of 1.80-190, a collimator for imaging the object on one face of the scintillation crystal, an array of photodetectors arranged around the opposite face of the scintillation crystal, and a light guide interposed between the opposite face of the scintillation crystal and the plurality of photodetectors. The light guide is selected to have an index of refraction of at least 1.60, higher than in the conventional gamma camera, whereupon it has been found that the detection efficiency and the positional accuracy of each scintillation event can be increased, to thereby increase the sensitivity and the spatial resolution of the gamma camera.
