The purpose of this work was to develop and validate a Monte Carlo model for a Dual Source Computed Tomography (DSCT) scanner based on the Monte Carlo N-particle radiation transport computer code (MCNP5). The geometry of the Siemens Somatom Definition CT scanner was modeled, taking into consideration the x-ray spectrum, bowtie filter, collimator, and detector system. The accuracy of the simulation...
Single photon emission computed tomography (SPECT) imaging with 123I-FP-CIT is of great value in differentiating patients suffering from Parkinson’s disease (PD) from those suffering from essential tremor (ET). Moreover, SPECT with 123I-IBZM can differentiate PD from Parkinson’s “plus” syndromes. Diagnosis is still mainly based on experienced observers’ visual assessment of the resulting images while...
