3D imaging technology promises reduced radiotherapy waiting lists and more accurate treatment

16.10.2003


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.


The AlignRT product consists of two sets of 3D cameras in each of the simulation and treatment rooms, which feed high-resolution real time 3D contour detail through to a monitor. An accurate 3D record of patient shape and position is recorded during simulation and calibrated to the treatment iso-centre. In the treatment room the system matches the reference image with the actual real-time image and calculates optimal couch coordinates to ensure the patient is aligned to the optimal treatment position.

AlignRT is non-invasive, does not require markers of any kind, and does not produce any ionising irradiation so the radiation therapist can be in the room whilst it is in operation. The AlignRT can be used in conjunction with all makes of linear accelerators. Comments Dr David Landau, Consultant Clinical Oncologist, Guy’s & St Thomas’ Hospital London, UK, “VisonRT’s ability to perform real time, 3D imaging of surface contours has the potential to make a real impact on the delivery of modern radiotherapy.”

The system is currently being evaluated at the Royal Marsden and St Thomas’ Hospitals in the UK and Norman Smith, CEO of Vision RT, will present the first scientific paper describing and evaluating this system at ASTRO on Tues 21st October at 12.30hrs in session L - Imaged Guided Therapy, entitled “Real-Time 3D surface imaging for patient positioning in Radiotherapy”. Vision RT will also be exhibiting a demonstrator model at Booth 2741.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
