This week's excitement involves an ion chamber change on one of our Linacs. The ion chamber is an integral part of the Linac.... Our old ionisation chamber being removed from the Linac head. Fun fact- the blue cable ties are more radio-resistant than the black and white cable ties and so don't become as brittle … Continue reading Ion chamber change

Ultrasonic Cavitation
Ultrasound Safety This week we're participating in a selection of imaging with non-ionising radiation workshops. One focus is ultrasound safety. Measuring power outputs, performing QC and understanding the clinical requirements of ultrasound vs patient safety. 2 indices are used to describe ultrasound safety: Thermal Index Thermal indices describe the potential for tissue temperature increasing during … Continue reading Ultrasonic Cavitation
Patients come first!
Today we're scheduled to spend a whole day on radiotherapy machine quality assurance (QA), performing the monthly checks on a particular machine to ensure that we are operating within the approved procedures with which we're allowed to carry out radiotherapy. These checks include mechanical checks of the couch positioning and isocentres (laser, mechanical, radiation), dosimetric … Continue reading Patients come first!
X-MR Testing
It turns out the most important weapon in a radiation safety physicist's arsenal is.... Micropore tape! Many metres used in the 8 hours of testing of this biplane interventional system. It was a very cool piece of kit with arms that move both independently and together with an astonishing number of joysticks and buttons. Hopefully … Continue reading X-MR Testing
