  • the role of a radiology physicist is to

  • provide support to medical imaging

  • departments within hospitals to make

  • sure really in a nutshell that patient

  • images are required at the best image

  • quality and the lowest possible

  • radiation dose and there's a number of

  • tasks that we do to enable that goal to

  • be met a medical physicist is a

  • scientific support person for diagnostic

  • imaging an interface between technology and

  • physicians an interface between

  • technology safety and everybody else it

  • enters the hospital environment on a day

  • to day basis I always check for example

  • in nuclear medicine the quality

  • assurance of every camera that we use so

  • it's daily floods and all that sort of

  • business to make sure that our cameras

  • are optimized for the best image quality

  • that we can provide for the diagnosis of

  • every patient that comes in to our

  • department optimized images means less

  • radiation dose faster throughput for

  • patients less waiting times at least

  • from our technical aspect if we can get

  • patients through at a timely manner we

  • can help the whole service improve

  • there's no such thing as a typical day

  • because we do a wide variety of tasks

  • but some of them would include quality

  • control of x-ray equipment monitoring of

  • staff doses monitoring or calculation of

  • patient radiation doses we do radiation

  • shielding calculations to make sure

  • there's lead in the walls and people

  • working in adjacent areas to say and we

  • do a lot of teaching to anybody working

  • with radiation

  • in the hospital and that extends beyond

  • the x-ray department operating theatres

  • and cardiac cath labs for example the

  • mere process of quality assurance and

  • quality control at a high level is

  • adding value all the time by providing

  • optimal image quality so that enables

  • our physicians to provide the best

  • diagnosis that they can at the lowest

  • radiation dose to the patients it

  • ensures that the service can provide a

  • wide range of clinical tests the main

  • way to describe this is as risk

  • mitigation so we're minimizing the risk

  • of miss calling a diagnosis because of

  • the assurance we're providing on data

  • quality we're minimizing unplanned

  • equipment outages through our quality

  • assurance programs and we're ensuring

  • regulatory compliance through the work

  • that we do for radiation safety

  • for nuclear medicine I see the pet MR

  • systems being the most exciting

  • development in the near future we've

  • already seen pet and CT work very well

  • together so pet MR should be another

  • leap forward in providing high quality

  • images for our physicians some of the

  • exciting things are certainly the new

  • technologies that are coming into the

  • radiology department particular new CT

  • scanners and new multi modality imaging

  • where they can combine different types

  • of imaging like fluoroscopy and CT on

  • the horizon for nuclear medicine there's

  • new instrumentation like the whole body

  • pet Explorer system this is massively

  • more sensitive than existing pet cameras

  • and is going to enable us to do tests or

  • duplicant protocols that we can't

  • contemplate now low-dose long-time point

  • that kind of thing this is the era of

  • personalized medicine and we are trying

  • to tailor all of our diagnostics and our

  • treatments to be the most appropriate

  • ones for that particular patient at this

  • particular point in time so it's

  • important from a safety point of view

  • but it's also important that we try and

  • maximize the treatment efficacy that we

  • can achieve
