Challenges Faced by Radiation Therapists in Cancer Treatment in Resource-Limited Environments
This session explores the various challenges encountered by radiation therapists in treating cancer patients within challenging healthcare environments, as discussed by Linnet Nhari from Gaborone. Key topics include difficulties with simulation techniques, limitations of shared diagnostic CT scanners, issues related to immobilization accessories, and connectivity problems with treatment planning systems. The presentation will highlight the impact of these challenges on patient treatment and outcomes, emphasizing the need for innovative solutions and adaptive strategies in radiation therapy.

Session 2: Challenges Experienced by Radiation Therapists in the Treatment of Patients with Cancer in Challenging Environments Linnet Nhari Life Gaborone
Simulation • Shared diagnostic CT Scanner • 70cm Bore vs 85-90cm • Immobilisation accessory limitations • Improvised flat board • FOV limitations • No connectivity with Mosaiq – setup notes • Use of CDs for image transfer ( lost/mixed/not working media)
Treatment Planning • CT images not send directly from CT scanner • Quality of CT images (contouring) • Iso-centre shift not independent of field shift • Undo button only for MLC contouring • Setup scan reference manual transfer introduces errors (auto transfer) • Limited planning technique for wide patients
Patient Treatment • Can not extend imaging panels from outside • No portals for couch through 90 degrees • Reproducibility of setups (carry-overs from simulation) • Height of couch • Heavy patient (transfer to linacc) • Automated angle sequencing
