ImagenPRO
Cardiac PET processing
One of the most crucial steps in cardiac PET imaging is processing the
data the right way. Unlike myocardial perfusion SPECT imaging, cardiac
PET is almost always viewed using attenuation and scatter correction. To
perform these corrections, a map of the patient's anatomy (an attenuation
map) is used to allow the software to compensate for the effects of
attenuation.
ImagenPRO is designed to perform the crucial step of registering the
emission and transmission data prior to reconstruction. In addition, it
patented transmission reconstruction algorithm is used to create
attenuation maps with smoother soft-tissue regions and crisper organ
boundaries.
Misregistration Correction
Misregistration can occur in myocardial perfusion PET because the
attenuation map and emission data set are not acquired simultaneously.
To correct for the influence of misregistration, ImagenPRO utilizes an
interactive rigid shift of the emission data relative to the transmission
data prior to reconstruction. Lateral and transaxial shifts are applied to
the emission data in real time to give the user feedback on the effect of
the corrections.
Bayesian Iterative Transmission Gradient Algorithm
ImagenPRO utilizes the Bayesian Iterative Transmission Gradient
Algorithm (BITGA) for reconstructing the attenuation maps from PET and
PET/CT systems. This algorithm produces smooth transmission scans
with good boundary detection. It also has corrections for metal in CT
based transmission scans.
