In vivo transit dosimetry methodology for whole breast intensity modulated radiation therapy
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background In vivo transit dosimetry using an electronic portal imaging device (EPID‐IVTD) is an important tool for verifying the accuracy of radiation therapy treatments. Despite its potential, the implementation of EPID‐IVTD in breast intensity modulated radiation therapy (IMRT) treatments has not yet been standardized, limiting its clinical

Facilitating 1.5T MR‐Linac adoption: Workflow strategies and practical tips
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background MR‐guided radiotherapy (MRgRT) offers new opportunities but also introduces workflow complexities requiring dedicated optimization. Implementing magnetic resonance linear accelerator (MR‐Linac) technology comes with challenges such as prolonged treatment times and workflow integration issues.

The global positioning system [PDF]
Physics Education, 1999 A hand-held global positioning system receiver displays the operator's latitude, longitude and velocity. Knowledge of GCSE-level physics will allow the basic principles of the system to be understood; knowledge of A-level physics will allow many important aspects of their implementation to be comprehended.

The global positioning system (GPS) was developed by the US Department of Defense in the early 1970s to serve military navigational requirements. The first satellite was launched in 1978 and the system was declared operational in 1995. It is based on a network of at least 24 satellites (with room for six further satellites) orbiting the Earth in nearly

Scientific American, 1996
Soon after the Soviets launched Sputnik in 1957, some scientists and engineers realized that radio transmissions from a satellite in a well-defined orbit could indicate the position of a receiver on the ground. The procedure uses the Doppler shift of radio signals as the satellite passes overhead. (A similar Doppler shift accounts for the sudden change
