Dosimetristen

Dosimetristen is the term used in Dutch-speaking contexts to refer to dosimetrists, healthcare professionals who specialize in radiation therapy dose calculation and treatment planning. They work as part of radiation oncology teams to design safe and effective radiation treatments for cancer patients, translating prescribed doses into concrete delivery plans.

Their core role involves using treatment planning systems to create three-dimensional dose distributions. They contour target volumes and organs at risk, optimize dose conformity and homogeneity, and calculate delivery parameters such as monitor units and beam arrangements. Dosimetristen perform plan quality assurance to verify that planned doses match what will be delivered, document plan specifications, and adjust plans as needed. They collaborate closely with radiation oncologists, medical physicists, and radiation therapists, and may contribute to brachytherapy planning when applicable.

Education and certification requirements vary by country. In many regions, dosimetrists hold a degree in medical dosimetry, medical imaging, physics, or radiation therapy, followed by specialized certification. Examples include credentialing through professional boards or associations that certify medical dosimetrists or equivalent competencies. Ongoing continuing education is common to keep up with advances in planning systems, imaging modalities, and treatment techniques.

Work environments are typically hospital-based radiation oncology departments or cancer centers. Tasks can range from initial plan development and optimization to plan verification, quality assurance, and treatment documentation. Dosimetristen operate under the supervision of radiation oncologists and medical physicists and play a key role in multidisciplinary cancer care by ensuring precise, individualized radiation therapy for patients.
