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 radiation therapy (EBRT) is included in the treatment regimen of the majority
of cancer patients. With the proliferation of hypofractionated radiotherapy treatment …

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 …

Four-dimensional (4D) ultrasound (US) is an attractive modality for image guidance due to
its real-time, non-ionizing, volumetric imaging capability with high soft tissue contrast …

Objective The accuracy of a transperineal three-dimensional ultrasound system (3DUS) was
assessed for prostate positioning and compared to fiducial-and bone-based positioning in …

Objective In image-guided EBRT of the prostate, transperineal ultrasound (US) probes exert
pressure on the perineum both during planning and treatment. Through tissue deformation …

Ultrasound can provide real-time image guidance of radiation therapy, but the probe-
induced tissue deformations cause local deviations from the treatment plan. If placed during …

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 3D ultrasound (US) images of the uterus may be used to adapt radiotherapy (RT)
for cervical cancer patients based on changes in daily anatomy. This requires accurate on …

Purpose Adaptive radiation therapy strategies could account for interfractional uterine
motion observed in patients with cervix cancer, but the current cone beam computed …
