BACKGROUND: Adaptive (ART) and image guided radiation therapy (IGRT) can improve target coverage and reduce unnecessary irradiation of organs at risk (OAR). The purpose of this study is to report the results of using mid-course imaging and a novel workflow with cone-beam computed tomography (CBCT) surveillance of dose to OAR to trigger adaptive replanning in head and neck radiotherapy. MATERIAL AND METHODS: Impact of radiation therapist (RTT) managed match protocol and mid-course imaging was assessed in two cohorts of consecutive patients receiving RT to the head and neck region, using computed tomography (CT) and CBCT-based dose verification respectively...

Ameer E Hassan, Sophie Amelot
Background and Purpose: Per the ALARA principle, reducing the dose delivered to both patients and staff must be a priority for endovascular therapists, who should monitor their own practice. We evaluated patient exposure to radiation during common neurointerventions performed with a recent flat-panel detector angiographic system and compared our results with those of recently published studies. Methods: All consecutive patients who underwent a diagnostic cerebral angiography or intervention on 2 modern flat-panel detector angiographic biplane systems (Innova IGS 630, GE Healthcare, Chalfont St Giles, UK) from February to November 2015 were retrospectively analyzed...

It is a challenge for radiation therapists (RTs) to keep pace with changing planning technology and techniques while maintaining appropriate skills levels. The ability of individual RTs to meet the demands of this constantly changing practice can only be assured through establishing clearly defined standards for practice and a systematic process for providing feedback on performance. Investigation into existing models for performance appraisal produced minimal results so a radiation therapy-specific framework was developed...

The treatment of rectal carcinoma is based on multidisciplinary strategy and multimodal approaches including gastrointestinal tract specialists, medical oncologists, radiation oncologists and surgery. The different objectives should be declined according to the characteristics of the tumours. The aim of the therapist would be to select the best strategy offering to the patient to be cured with as less as possible late adverse toxicity. The challenge of the treatment of small tumours is to maintain a functional anal sphincter while minimizing the risk of local recurrence...

The dosimetric uncertainties associated with radiotherapy through hip prostheses while overriding the implant to a set density within the TPS has not yet been reported. In this study, the uncertainty in dose within a PTV resulting from this planning choice was investigated. A set of metallic hip prosthetics (stainless steel, titanium, and two different Co-Cr-Mo alloys) were CT scanned in a water bath. Within the TPS, the prosthetic pieces were overridden to densities between 3 and 10 g/cm(3) and irradiated on a linear accelerator...

INTRODUCTION: Modern external beam radiation therapy treatment delivery processes potentially increase the number of tasks to be performed by therapists and thus opportunities for errors, yet the need to treat a large number of patients daily requires a balanced allocation of time per treatment slot. The goal of this work was to streamline the underlying workflow in such time-interval constrained processes to enhance both execution efficiency and active safety surveillance using a Kaizen approach...

A more than 100-year period, where the prostate was only seen and treated as a whole is coming to an end right now. Finally, high resolution imaging is providing deep insights and detailed information so that new therapeutic procedures can aim for the smallest targets within the gland. The long-standing wish of patients for individual noninvasive diagnostics and treatment of prostate diseases can now be fulfilled by providing new tailored concepts; however, in order to transfer the enormous amount of new information into the specific clinical patient situation, a closely knit interdisciplinary approach is required...

Context • People are increasingly exposed to low frequency (LF) electromagnetic fields (EMFs), mainly from electricity distribution networks and electronic devices. Critics of this widespread exposure believe that it can have detrimental effects on the human body. On the other hand, many in vivo and in vitro studies have claimed that low frequency electromagnetic therapy can function as a form of alternative medicine and that therapists can treat disease by applying electromagnetic radiation or pulsed EMFs to the body or cells...

BACKGROUND: In IGRT of deformable head-and-neck anatomy, patient setup corrections are derived by rigid registration methods. In practice, experienced radiation therapists often correct the resulting vectors, thus indicating a different prioritization of alignment of local structures. Purpose of this study is to transfer the knowledge experts apply when correcting the automatically generated result (pre-match) to automated registration. METHODS: Datasets of 25 head-and-neck-cancer patients with daily CBCTs and corresponding approved setup correction vectors were analyzed...

During the last twenty years, a huge progress has been achieved in the treatment of liver cancer and recent strategies include interventional radiology, chemotherapy regimens and surgery. Meanwhile, Stereotactic Body Radiation Therapy (SRBT) has developed in the treatment of all organs with millimetre accuracy, very few side effects and a high control rate. So, SRBT has become a therapeutic weapon in his own right in liver tumour treatment. Many publications have reported encouraging results in colorectal liver metastasis, hepatocellular carcinoma on cirrhosis and peripheric cholangiocarcinoma...
