Optimization of imaging parameters of an investigational photon-counting CT prototype for lung lesion radiomics
In person: 24 February 2022 • 8:40 AM - 9:00 AM PST
This study's aim was to evaluate and optimize the imaging parameters for lung lesion radiomics using the new NAEOTOM Siemens Healthineers photon-counting CT prototype. Due to the limited supply of patient data, the prototype was optimized through virtual clinical trials. Virtual patients were modeled at three BMIs, each including three lesions with varying spiculation levels. The DukeSim software was used to simulate imaging of the virtual patients under varying acquisition and reconstruction parameters. The segmented lesion results showed dose had an insignificant effect on radiomics accuracy, and increasing matrix size was found to increase the accuracy of radiomics measurements.
