A bar-shaped scintillator converts incident collimated gamma rays to light pulses which are detected by a row of photoelectric tubes positioned along the output face of the scintillator wherein each tube has a convexly curved photocathode disposed in close proximity to the scintillator. Electronic circuitry connected to the output of phototubes develops the scintillation event x-axis position coordinate electrical signal with good linearity and with substantial independence of the spacing between the scintillator and photocathodes so that the phototubes can be positioned as close to the scintillator as possible to obtain reduced distortion in the field of view and improved spatial resolution. A mechanical drive of the scanner results in an image of the gamma ray source being formed by sequencing the developed scintillation position coordinate signals in the y-axis dimension. (auth)
