Vision RT Limited’s new system for radiotherapy patient alignment should allow rapid positioning with error margins reduced from centimetres to within millimetres, according to data to be presented at the October ASTRO meeting. Dr. Norman Smith, CEO of Vision RT, will give a paper on Vision RT’s 3D body imaging technology and describe how it can impact positively on the speed and accuracy of radiotherapy treatment, at the 45th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Salt Lake City, USA, on 21 October 2003.
The information to be presented at the meeting will include data collected at research and clinical test sites to demonstrate how Vision RT’s new system for aligning the patient on the treatment couch can reduce set-up time and assist in the delivery of the high energy beam accurate to within mms rather than cms of the target area. The system could help overcome the two key limiting factors in radiotherapy efficiency, namely set-up time and inaccuracies which lead to damage to healthy tissue arising from the lack of effective patient-positioning technologies.
Fifty per cent of cancer patients require radiotherapy and radiotherapy rooms cost over £2.5m ($4 m) to equip so facilities tend to be limited. At present the significant proportion (up to two thirds) of an appointment is taken up with aligning the patient to the accelerator beam. Making more efficient use of equipment will allow for shorter appointments and increase patient throughput, which could bring down radiotherapy waiting lists. Minimising set-up errors should also allow for higher radiation doses to be administered if damage to healthy tissue can be minimised.

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
