High-sensitivity cardiac SPECT system design with collimator-less interspaced mosaic-patterned scintillators.
Frontiers in medicine(2023)
摘要
The study reveals a promising approach to high-sensitivity SPECT imaging without a heavy-metal collimator. In cardiac imaging, this approach opens the way to a very fast cardiac scan with good resolution. Further works are ongoing to build a practical 3-D imaging system based on the existing design.
