Welcome to the Conolly lab website. Things we work on:
Pre-polarized MRI: Prepolarized MRI (PMRI) with pulsed electromagnets has the potential to produce diagnostic quality 0.5- to 1.0-T images with significantly reduced cost, susceptibility artifacts, specific absorption rate, and gradient noise. In PMRI, the main magnetic field cycles between a high field (Bp) to polarize the sample and a homogeneous, low field (B0) for data acquisition. This architecture combines the higher SNR of the polarizing field with the imaging benefits of the lower field.
Magnetic Particle Imaging: The Magnetic Particle Imaging (MPI) method directly images the magnetization of Super-Paramagnetic Iron Oxide (SPIO) contrast agents commonly used in MRI with significantly improved SNR.
Susceptibilty Matched Foam: Tissue susceptibility matched pyrolytic graphite (PG) foam reduces static field gradients at air and tissue boundaries leading to reduced artifacts and a more uniform B0 static field.
