Compare the work, not the label
Should you choose radiotherapy or imaging physics?
Choose by the work you want to do, not by which title sounds more impressive. Radiotherapy physics focuses on accurate treatment delivery; imaging physics focuses on useful diagnostic information and proportionate risk. Both need measurement, computing, quality systems and teamwork.
How does the work compare?
These are broad patterns rather than complete job descriptions. Departments, rotations and seniority change the mix.
| Area | Clinical purpose | Typical technical work |
|---|---|---|
| Radiotherapy physics | Deliver radiation treatment accurately | Treatment planning, dose calculation, dosimetry and treatment-machine assurance |
| Ionising imaging | Create useful x-ray and CT images with proportionate dose | Image quality, patient dose, optimisation, equipment checks and radiation protection |
| Non-ionising imaging | Create and measure images without ionising radiation | MRI, ultrasound and optical performance, safety and clinical implementation |
| Nuclear medicine | Image body function or deliver radionuclide treatment | PET/SPECT systems, activity measurement, dosimetry, quality and radiation safety |
What stays similar across the specialties?
You will still work within a clinical service, not as an isolated physicist.
- Commissioning and quality assurance
- Investigating unexpected results
- Data analysis, software and documentation
- Risk assessment and change control
- Explaining technical evidence to a multidisciplinary team
Which current England STP choices cover imaging?
The current names are Imaging with Non-Ionising Radiation and Radiation Safety and Diagnostic Radiology. Nuclear Medicine is listed separately. Check the exact choices and post information for the live recruitment round.
Which questions will help you choose?
- Would you rather improve a treatment plan or optimise a diagnostic test?
- Which equipment and physical principles would you enjoy learning in depth?
- Which risks and service pressures would you be comfortable owning?
- Do you prefer work closely tied to one patient's treatment or work that can improve an imaging service for many patients?
- What did you learn from official descriptions, events or conversations that changed your first impression?
