Brief
The article discusses using pulse height spectroscopy to measure the depth-dependent light escape efficiency and optical Swank factor of scintillators, particularly focusing on CsI scintillators with various thicknesses and optical designs.
Summary
This article, published in Medical Physics, describes a new method for calculating the depth-dependent light escape efficiency and optical Swank factor of scintillators. The authors found that the optical design of a scintillator, such as the presence of a reflective backing or fiber optic plate, is the primary factor that determines these properties. The thickness of the scintillator was found to have a less significant impact. The authors suggest that their findings could be used to improve the design of scintillators for use in medical imaging.
