1.
Dixit N, Daniel B, Hargreaves B, Pauly J, Scott G
Med Phys
. 2021 Jul;
48(10):6069-6079.
PMID: 34287972
Purpose: Almost one in four lumpectomies fails to fully remove cancerous tissue from the breast, requiring reoperation. This high failure rate suggests that existing lumpectomy guidance methods are inadequate for...

Dixit N, Pauly J, Scott G
Magn Reson Med
. 2019 Dec;
84(2):1035-1047.
PMID: 31883207
Purpose: We explore the use of thermo-acoustic ultrasound (TAUS) to monitor temperature at the tips of conductive device leads during MRI. Theory: In TAUS, rapid radiofrequency (RF) power deposition excites...

Jordan C, Thorne B, Wadhwa A, Losey A, Ozhinsky E, Kondapavulur S, et al.
IEEE Trans Biomed Eng
. 2019 Jun;
67(3):876-882.
PMID: 31247538
Interventional magnetic resonance imaging (MRI) could allow for diagnosis and immediate treatment of ischemic stroke; however, such endovascular catheter-based procedures under MRI guidance are inherently difficult. One major challenge is...

Dixit N, Stang P, Pauly J, Scott G
IEEE Trans Med Imaging
. 2017 Oct;
37(2):536-546.
PMID: 29053449
Patients who have implanted medical devices with long conductive leads are often restricted from receiving MRI scans due to the danger of RF-induced heating near the lead tips. Phantom studies...

Zheng B, Goodwill P, Dixit N, Xiao D, Zhang W, Gunel B, et al.
IEEE Trans Biomed Circuits Syst
. 2017 Jul;
11(5):1041-1052.
PMID: 28742047
Inductive sensor-based measurement techniques are useful for a wide range of biomedical applications. However, optimizing the noise performance of these sensors is challenging at broadband frequencies, owing to the frequency-dependent...

Lu J, Grafendorfer T, Zhang T, Vasanawala S, Robb F, Pauly J, et al.
IEEE Trans Med Imaging
. 2016 Jul;
35(12):2558-2567.
PMID: 27362895
Q-spoiling is the process of decoupling an MRI receive coil to protect the equipment and patient. Conventionally, Q-spoiling is performed using a PIN diode switch that draws significant current. In...

Magn Reson Med
. 2015 Sep;
76(3):1015-21.
PMID: 26418283
Purpose: To design, construct, and validate a semiflexible 64-channel receive-only phased array for pediatric body MRI at 3T. Methods: A 64-channel receive-only phased array was developed and constructed. The designed...

Magn Reson Med
. 2014 Mar;
73(3):1328-39.
PMID: 24623586
Purpose: The concept of a "radiofrequency safety prescreen" is investigated, wherein dangerous interactions between radiofrequency fields used in MRI, and conductive implants in patients are detected through impedance changes in...

Stang P, Conolly S, Santos J, Pauly J, Scott G
IEEE Trans Med Imaging
. 2011 Sep;
31(2):370-9.
PMID: 21954200
Magnetic resonance imaging (MRI) pulse sequence consoles typically employ closed proprietary hardware, software, and interfaces, making difficult any adaptation for innovative experimental technology. Yet MRI systems research is trending to...
