QA Dosimetry in Cancer Radiation Therapy: Ensuring Accurate & Safe Treatment

Quality Assurance (QA) Dosimetry verifies that prescribed radiation doses are delivered accurately and safely during cancer treatment.

Key Roles

1. Treatment planning verification: Compares planned vs. delivered dose distributions to ensure target coverage and healthy tissue sparing.
2. Machine calibration and output verification: Regular checks on linear accelerators to detect performance deviations.
3. Patient dose verification: Confirms actual dose matches plan, preventing underdosing (tumor control failure) or overdosing (healthy tissue damage).
4. Quality control of delivery: Ongoing checks throughout treatment for protocol adherence.
5. Regulatory compliance: Meets national/international standards for radiation therapy quality and safety.

QA Dosimetry is essential for treatment accuracy, patient safety, and optimal outcomes.
