Developing a policy framework to support role extension in diagnostic radiography in ghana
A global shortage of radiologists is affecting the timely provision of imaging reports and thus healthcare delivery. This situation has been the main driving factor behind successful role extension by radiographers into areas that traditionally were within the scope of radiologists, including image interpretation and reporting. The shortage of radiologists is even worse in developing countries like Ghana. There is a need for policy to guide the introduction and implementation of role extension in Ghana.

The potential for haptic touch technology to supplement human empathetic touch during radiotherapy
Radiotherapy for cancer is an effective treatment but requires precise delivery. Patients are required to remain still in the same position during procedure which may be uncomfortable. This combined with high anxiety experienced by patients, and feelings of isolation, have indicated a need for comfort interventions. Care conveyed through empathetic touch promotes comfort, individual attention and presence and provides both psychological and physical comfort at the same time. Evidence in nursing and care literature showed that empathetic touch interventions have a significant role in promoting comfort, facilitating communic...

Delivered Dose Distribution Estimation for Online-Adaptive Prostate SBRT on the MR-Linac
The MR-Linac (MRL) platform offers the ability to create daily-adapted treatments that reflect daily changes in a patient ’s anatomy. However, MRL treatment fractions can take up to 75 minutes for patient setup, treatment imaging, adaptive re-planning, quality assurance and delivery. Large intra-fraction changes in pelvic organs are well documented, but little is known about the dosimetric effect of these changes in the context of long, adaptive treatment delivery sessions. Herein, we describe an innovative clinical process to estimate the actual delivered dose distribution at the time of MR guided adaptive treatment...

The Development of MR-Based, Online Adaptive Techniques for the Treatment of Liver Cancer
The use of curative radiotherapy (RT) in liver cancer has become increasingly feasible with new technical advances; our institution treats approx. 100 liver patients per year. One challenge in liver RT is accurately targeting the tumor while avoiding the surrounding normal liver and adjacent normal tissues. Liver motion during breathing also adds complexity to targeting lesions accurately. Unfortunately, the use of CBCT provides poor contrast for image guidance. With the advent of the MR-Linac, use of MR imaging prior to treatment delivery facilitates the potential to visualize the liver tumor and quantify breathing motion...

Feasibility of Utilizing EPIC-CP to Guide Symptom Management for Clinically Localized Prostate Cancer Patients Undergoing Hypofractionated Radiotherapy
Utilization of patient-reported outcome measures (PROMs) to guide symptom management during radiation therapy has shown to be more sensitive to changes in health status and might detect the exact onset of the toxic effects of radiotherapy more accurately than clinician-reported outcomes. The Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) is a validated 16-item, diseasespecific PROM that targets the unique needs of men with prostate cancer (PCa) and evaluates the five HRQOL domains of urinary incontinence, urinary irritation/obstruction, bowel related symptoms, sexual dysfunction and hormonal sympt...
