Developing a MLC modifier program to improve fiducial detection for MV/kV imaging during hypofractionated prostate volumetric modulated arc therapy.

Purpose: To develop an Eclipse plug-in (MLC_MODIFIER) that automatically modifies control points to expose fiducials obscured by MLC during VMAT, thereby facilitating tracking using periodic MV/kV imaging.

Method: Three-dimensional fiducial tracking was performed during VMAT by pairing short-arc (3°) MV digital tomosynthesis (DTS) images to triggered kV images. To evaluate MLC_MODIFIER efficacy, two cohorts of patients were considered.

Professional resilience in GPs working in areas of socioeconomic deprivation: a qualitative study in primary care.

Background: GPs working in areas of high socioeconomic deprivation face particular challenges, and are at increased risk of professional burnout. Understanding how GPs working in such areas perceive professional resilience is important in order to recruit and retain a GP workforce in these areas.

Aim: To understand how GPs working in areas of high socioeconomic deprivation consider professional resilience.
