Immediately adjacent to this room is an operating room used primarily for neurosurgery. Between the two rooms is a radiofrequency shielded sliding double door that allows for transport of a patient between the two systems. To facilitate the transfer, the tables for the operating room and the MR system have been modified to accommodate a specially designed table-top that can slide from the operating room to the MRI system, and vice-versa. Together, the two rooms form an intra-operative suite.

WIMRPETMR1

WIMRPETMR1

WIMRPETMR1 is a PET/MR scanner (GE Signa PET/MR, GE Healthcare, Waukesha WI), consisting of a 3.0 T MRI system with an integrated PET scanner, located in room B1258B of the Wisconsin Institutes for Medical Research (WIMR). It was installed in 2015. It is capable of simultaneous acquisition of PET and MR images for clinical and research purposes, with a schedule from 8:00 AM to 5:00 PM, Monday through Friday.  The system has 32 receivers and a variety of radiofrequency transmit and/or receive coils. The bore diameter is 60 cm.

The PET system contains state-of-the-art silicon photomultiplier (SiPM) detectors, and can reconstruct images with or without time-of-flight (TOF) and point-spread function modeling (SharpIR). The extended S/I coverage (25 cm) of the PET system results in improved detection sensitivity, which may allow for reduced doses of radiopharmaceuticals.  Attenuation and scatter corrections are achieved through MR-based or atlas-based attenuation correction methods. The PET spatial resolution is approximately 4.0 mm. Cardiac and respiratory gating is possible for both PET and MR imaging.
