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: First quantum photonic circuit with electrically driven light source

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.

Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
