PURPOSE This study evaluates the hypothesis that optimising the path of a high intensity focused ultrasound (HIFU) treatment's N focal zone heating pulses can significantly reduce treatment time, and identifies the underlying bio-thermal principles. MATERIALS AND METHODS Thirty-one scanning paths were investigated using 3D simulations, with a minimum(More)
PURPOSE This study evaluated the HIFU treatment time reductions attainable for several scan paths when optimising the heating approach used (single, discrete pulses versus volumetric scanning) and the paths' focal zone heating locations'; number (N(FZL)), spacings, sequencing order, number of heating cycles (N(CYCLES)), and heating times. Also evaluated(More)

Our SPECT research has two main areas. One is instrumentation development and the other is image reconstruction development. In instrumentation development, we are working on three projects that develop methods for (1) multi-pinhole small animal SPECT system calibration and normalization, (2) skew-slit collimation for small animal SPECT imaging, and (3) a(More)
