Uvod: Jednofotonska emisiona tomografija (SPECT) značajno je unaprijedila nuklearno-medicinsku dijagnostiku. Nedostatak SPECT metode su relativno niski signal-šum odnos (SNR) kao i kontrast-šum odnos (CNR). Nizak broj fotona slike predstavlja veliki problem kod SPECT snimanja zbog smanjenja signala uz povećanje šuma (pozadine slike). Zadnjih godina...
