WORKSHOP ‘ENSURING QUALITY IN IGRT’ – June 10, 2026, Sofia
From June 11 to 13, Bulgaria will host the International Symposium on Radiation Exposure Monitoring in Diagnostic Imaging (REM2026), for which you are invited to register. We expect the symposium to receive accreditation from EBAMP for continuing education of medical physicists.
We are pleased to invite you to participate in a pre-symposium workshop focused on quality assurance in image-guided radiation therapy (IGRT), which will be held on June 10, 2026, in Sofia. The event is organized by BSBPE with the support of the ‘Röntgen’ Foundation and NCRRP and with the participation of two of the experts invited to the REM2026 symposium. The main speaker will be Sébastien Gros from the USA, and Efi Kousouveli, President of EFOMP, will also take part in the meeting (their brief CVs are below).
Preliminary Program
12:30 – 13:00
Opening and Introduction: State of IGRT Practice in Bulgaria
13:00 – 14:30
CBCT Dosimetry – Current Status, Challenges, and Practical Experience
14:30 – 15:00
Coffee Break
15:00 – 16:30
Optimization of the Clinical Application of CBCT – Frequency, Protocols, and Image Quality
We invite medical physicists working in radiation therapy or interested in the topic to participate.
Participation in the workshop is free and is not linked to registration for the symposium.
In view of the hall’s capacity and to ensure an effective discussion, the number of participants is limited to 50 people. Participation requests will be reviewed and approved in the order of their submission (registration timestamp), until the available spots are filled. Once the maximum capacity is reached, a waiting list will be created, and those on it will be included as spots become available.
After the conclusion of the working meeting (4:30 PM), a joint meeting between BSBPE and EFOMP will be held to discuss opportunities for future cooperation.
Location: NCRRP, 1606 Sofia, 3 St. George Sofiyski Street, Building 7, 2-nd floor, Training Hall 225
