Medical Dosimetrist

Responsibilities:

1. Treatment Planning & Dosimetry:

• Develop comprehensive radiation treatment plans using Monaco and Lumonus software in collaboration with radiation oncologists and medical physicists.

• Create optimal dose distributions for a wide spectrum of tumour sites and treatment modalities, including conventional 3D-CRT, IMRT, VMAT, SBRT, and SRS techniques.

• Perform complex dose calculations and optimisation to deliver prescribed radiation doses while sparing critical structures.

• Generate and evaluate treatment plans using advanced computer algorithms and manual verification methods.

• Identify and contour normal tissue and dose-limiting structures utilising multiple imaging datasets (CT, MRI, PET).

• Create digitally reconstructed radiographs (DRRs) and reference images for treatment verification and portal imaging.

2. Clinical Operations:

• Collaborate closely with radiation oncologists, medical physicists, and radiation therapists to ensure optimal treatment delivery.

• Maintain plan return time to require standards and deadlines.

• Perform quality assurance activities on treatment plans and maintain comprehensive documentation.

• Assist in simulation procedures and tumour localisation using various imaging modalities.

• Ensure all treatment planning activities comply with South African healthcare regulations and international standards.

3. Quality Assurance & Documentation:

• Perform dose calculations and verification of treatment plan accuracy using approved methods.

• Maintain detailed and accurate patient records, documenting all pertinent treatment planning information.

• Participate in departmental quality assurance programmes for equipment and treatment planning systems.

• Monitor and document treatment plan performance and patient outcomes data.

4. Professional Development & Training:

• Provide guidance and training to junior dosimetry staff.

• Stay current with advances in treatment planning techniques and radiation therapy technologies.

• Participate in continuing education and professional development activities.

• Contribute to clinical research and the development of new treatment planning techniques.

Qualifications:

• Bachelor's Degree in Medical Dosimetry, Physical Sciences, or equivalent qualification as recognised by the Health Professions Council of South Africa (HPCSA).

• Certified Medical Dosimetrist (CMD) or equivalent South African certification, or board eligible.

• Minimum 3-5 years of clinical experience in medical dosimetry with demonstrated competency across multiple treatment modalities.

• Proven experience in treatment planning for complex cases, including IMRT, VMAT, SBRT, and stereotactic treatments.

• Strong analytical and problem-solving skills with attention to detail and accuracy.

• Excellent communication and interpersonal skills for effective collaboration with multidisciplinary teams.

Technical Requirements:

• Comprehensive knowledge of contemporary radiotherapy planning techniques, including 3D-CRT, IMRT, VMAT, SBRT, and SRS.

• Experience with treatment planning systems (Monaco, or similar platforms) 

• Expert knowledge of dose calculation algorithms, plan optimisation techniques, and quality assurance protocols.

• Proficiency in radiation physics principles, anatomy, and radiation biology.

• Understanding of radiation safety protocols and regulatory compliance requirements.

• Experience with multiple imaging modalities (CT, MRI, PET) for treatment planning purposes.
