Diagnostic Radiography (M.Sc.) postgraduate personal statement example

Personal statement example

For my final-year physics project I put black electrical tape over the lens of a twelve-pound webcam and photographed nothing, several thousand times. I was measuring how the random variation between pixels changed with exposure time and sensor temperature, using a cooling pack from a first-aid kit and a thermometer taped beside the circuit board. The results were unglamorous: a dark-current contribution that rose with temperature, read noise that stayed stubbornly constant, and a lot of time spent learning to write Python scripts that averaged frames without crashing my laptop. What stayed with me was the idea that every image carries a trade-off between signal and noise, and that someone has to choose where to sit on that trade-off. In radiography that choice involves a person receiving a dose, which is why I want to train as a diagnostic radiographer rather than continue with physics alone.

My degree gave me a solid grounding in electromagnetism, atomic physics and the interaction of radiation with matter, including photoelectric absorption and Compton scattering. I understand, in principle, why bone appears bright on a plain film and why scatter degrades contrast. I am aware, though, that knowing the physics is a small part of the job. Positioning, anatomy, infection control and communicating with someone who is frightened or in pain are skills I have not yet been taught, and I am looking forward to learning them properly in a structured setting and on clinical placement.

For the past two years I have worked weekend shifts as a porter at my local general hospital, which I started to fund my final year and continued after graduating. Much of the work is moving patients between wards and imaging departments, collecting samples and delivering equipment. I have taken patients to the X-ray and CT waiting areas many times, but I hand over at the door, so I have not watched examinations being carried out. What I have seen is everything around them: the older man who needed his hearing aid found before he could follow any instructions, the young woman on a trolley who asked me three times whether the scan would hurt, the radiographer who came out to meet a confused patient and spoke to her by name before anything else. Portering has taught me to keep to time under pressure, to check identity wristbands every single time, and to judge when someone wants conversation and when they want quiet.

Outside work I coach a junior squad at my swimming club on Tuesday evenings. Teaching an eight-year-old to keep her head still during front crawl has made me better at giving one clear instruction at a time and showing rather than telling, which I suspect will be useful when asking patients to hold a position. I also do a weekly shop for an elderly neighbour, which mostly involves deciphering her handwritten lists and remembering which brand of tea is acceptable.

To prepare for this course I have been reading Clark's Positioning in Radiography, slowly and with an anatomy atlas open beside it, and revising the ionising radiation principles of justification and optimisation, keeping doses as low as reasonably achievable. I have also returned to my project data to think about how detector noise relates to the exposure factors a radiographer selects, although I know that clinical detectors are far more sophisticated than my webcam.

I am a careful, practical person who is comfortable with numbers and with people, and who already knows what a busy hospital feels like on a Saturday night. I would bring steady habits and genuine curiosity to postgraduate training, and I am ready for the demands of combining academic study with clinical placements.
