Brain SPECT Collimator Design
PublicDownloadable Content
open in viewerA multi-pinhole (MPH) collimator is designed to pair with an existing fan-beam collimator for single-photon emission computed tomography (SPECT). A mechanical design has been developed for constructing a brain-dedicated MPH collimator that will replace a commercial single pinhole collimator for general imaging. The spatial and weight constraints are satisfied. Material deformation during operation is simulated and used to ensure safety and imaging accuracy. Monte-Carlo simulation of the gamma-ray interaction is performed to simulate brain imaging and validate the model geometry. The student has also determined the operation type of the shutter mechanism for specific apertures that will allow or restrict the passage of photons to adapt the imaging characteristics of the collimator.
