PET/MR ZTE MRAC
PET/MR zero echo time (ZTE) scan for head attenuation and Q.Static . PET/MR ZTE MRAC images to be acquired for post-processing and reader assessment. Zero Echo Time (ZTE) scan for head attenuation Zero Echo Time (ZTE) scan for head attenuation: The GE SIGNA PET/MR MP26 software platform includes the zero echo time (ZTE) scan for head attenuation and Q.Static. The ZTE MR software feature has the potential to enable better visualization of bones, including those in the head, by employing optimal head attenuation correction in PET/MR. PET/MR ZTE MRAC
PET/MR Q Static (Q. MRAC)
Q.Static (Q. MRAC) for respiratory motion correction. PET/MR Q Static (Q. MRAC) images to be acquired for post-processing and reader assessment. PET/MR Q Static (Q. MRAC) Q.Static (Q. MRAC) for respiratory motion correction: An improved Q.Static feature with Q. MRAC, where phase matching the MRAC with the quiescent phase is employed to get more accurate attenuation correction for our Q.Static PET images. PET/MR Q Static (Q. MRAC)
