In modern radiotherapy, verification of the treatment to ensure the target receives the
prescribed dose and normal tissues are optimally spared has become essential. Several …

External beam radiotherapy (EBRT) is one of the curative treatment options for prostate
cancer patients. The aim of this treatment option is to irradiate tumor tissue, while sparing …

Purpose: A quantitative 3D intramodality ultrasound (US) imaging system was verified for
daily in‐room prostate localization, and compared to prostate localization based on …

Background The accuracy of the Elekta Clarity™ three-dimensional ultrasound system
(3DUS) was assessed for prostate positioning and compared to seed-and bone-based …

Purpose To evaluate the impact of transabdominal probe pressure on prostate positioning
with an intramodality ultrasound (US) image-guided-radiotherapy system and to quantify …

Purpose To demonstrate robustness of thermooacoustic range verification to acoustic
heterogeneity and discrepancies between assumed and true propagation speed, ie …

Purpose The aim of this study was to evaluate a new system based on transperineal
ultrasound (TP-US) acquisitions for prostate and post-prostatectomy pre-treatment …

Purpose: Imaging of patient anatomy during treatment is a necessity for position verification
and for adaptive radiotherapy based on daily dose recalculation. Ultrasound (US) image …

Purpose To evaluate the accuracy of an intra-modality trans-abdominal ultrasound (TA-US)
device against soft-tissue based Cone-Beam Computed tomography (CBCT) registration for …

Conventional ultrasound (US) devices use the time of flight (TOF) of reflected US pulses to
calculate distances inside the scanned tissues and thus create images. The speed of sound …
