“…The TCM signal processing algorithms are described in detail by Chen et al [20, 21] and briefly presented below. The backscattered pulse-echo signals are analyzed in the frequency domain using the Fast Fourier Transform (FFT) to derive the ΔE value for each ablative site as described by eqs.…”

“…Eight histologically confirmed organ confined prostate cancer patients were enrolled as per the clinical study protocol [22] with intent to ablate the entire prostate gland with the TCM software based Sonablate 500 device [21, 23]. All patients were under local epidural anesthesia for the HIFU procedure.…”

“…In addition, the vulnerability to motion artifacts and tissue deformation limit the quantitative assessment. Therefore, one of the commercial HIFU systems only illustrates the low, medium and high degree of change in backscattered energy levels to provide qualitative information [12]. In contrast, although the cost of MRI is quite high, the ability of providing real-time thermography makes MRI the sole HIFU guidance modality approved by FDA.…”
