The quality and realism of simulated images is currently limited by the quality of the digital phantoms used for the simulations. The transition from simple raster based phantoms to more detailed geometric (mesh) based phantoms has the potential to increase the usefulness of the simulated data. A preliminary breast phantom which contains 12 distinct tissue classes along with the tissue properti...

enhancement after contrast injection, with 4 lesions present, 10 min after contrast injection.(b) Image obtained by subtracting non-enhanced image initial image from the final image at 10 min improves visualization of simulated lesions. Arrow indicates lesion for which subsequent error calculation has been performed (see below) (c) signal intensity vs. time (SIT) curve curves associated with le...
Purpose MR-guided radiotherapy has different requirements for the images than diagnostic radiology, thus requiring development of novel imaging sequences. MRI simulation is an excellent tool optimizing these new sequences; however, currently available software does not provide all necessary features. In this paper, we present a digital framework testing sequences that incorporates anatomical st...
A positioning QA procedure for Varian's 2D/2D (kV/MV) and 3D/3D (planCT/CBCT) matching was developed. The procedure was to check: (1) the coincidence of on-board imager (OBI), portal imager (PI), and cone beam CT (CBCT)'s isocenters (digital graticules) to a linac's isocenter (to a pre-specified accuracy); (2) that the positioning difference detected by 2D/2D (kV/MV) and 3D/3D(planCT/CBCT) matc...
