Corcoles J, Zastrow E, Kuster N
Phys Med Biol . 2017 Mar; 62(12):4711-4727. PMID: 28252443
The increasing use of multiple radiofrequency (RF) transmit channels in magnetic resonance imaging (MRI) systems makes it necessary to rigorously assess the risk of RF-induced heating. This risk is especially...

Burfeindt M, Zastrow E, Hagness S, Van Veen B, Medow J
Phys Med Biol . 2011 Apr; 56(9):2743-54. PMID: 21464536
We present a numerical study of an array-based microwave beamforming approach for non-invasive hyperthermia treatment of pediatric brain tumors. The transmit beamformer is designed to achieve localized heating-that is, to...

Zastrow E, Hagness S, Van Veen B, Medow J
IEEE Trans Biomed Eng . 2011 Jan; 58(6):1574-84. PMID: 21216700
A noninvasive microwave beamforming strategy is proposed for selective localized heating of biological tissue. The proposed technique is based on time multiplexing of multiple beamformers. We investigate the effectiveness of...
