Our research group is equipped with various facilities and equipments and has access to multiple institutional resources:
The Beddar Laboratory is a 300 sq. ft. space located within 50 m of clinical linear accelerators and brachytherapy treatment units at the ACB building on the main campus, enabling easy transport and access to the clinical environment. Other laboratory space near Beddar’s office is also available for light measurement experiments. This space is next to a research Co-60 AECL Limited Theratron machine for irradiation experiments. Additional laboratory space at the Proton Center is available for Beddar Lab projects.
Light measurement equipment
Most of the Beddar Lab research projects involve the measurement of scintillation light. The group owns a growing number of photodetectors, particularly deeply-cooled CCD and EMCCD cameras, as well as spectrometers. The Beddar Lab has an assortment of optical equipment and materials from Thorlabs Instruments and Edmund Optics research-grade optical benches to conduct experiments, an assortment of photomultiplier tubes, photodiodes, optical couplers, lenses, filters, translation stages, camera objectives, and other electronic equipment needed for basic signal processing and light measurements. The group also has high-precision luminance sources and calibration lamps, as well as multiple fiber dosimeters developed in-house. All the required equipment to build additional detectors is also available. Other laboratory instrumentation includes a complement of electronic components, dual tracking power supplies, digital voltmeters, oscilloscope, wave-form generators, soldering stations, and desoldering tools. Other basic equipment is available within the institution’s machine shops.
Computing Physics resources
The Radiation Physics department maintains a significant network of dedicated computing resources, and a development team to support clinical and research needs. Departmental resources include a network accessible, multi-processor server dedicated to the development of photon and proton dose calculation, a 200 CPU Linux computer cluster for Monte Carlo calculations, and parallel processing and optimization applications. In addition, Radiation Physics faculty including an 8000 CPU, 64 bit computing cluster that supports MCNPX and Geant4 Monte Carlo applications, as well as ROOT, MATLAB, OpenGL, and LabView development environments.
All laboratory personnels are located in adjacent offices, facilitating easy interactions, synergism, and a collaborative research environment. Office computers are equipped with data processing and publication software. The institution provides administrative support and printing services, and it maintains a scientific publications department to assist with manuscript preparation.
Treatment Delivery Equipment
In addition to the proton therapy center, there are approximately 20 linear accelerator units, seven on-board imaging and cone-beam CT systems, four pulsed dose rate remote afterloading systems and three high dose rate remote afterloading systems at the main campus. Two of the treatment rooms have CT-on-rails units.
The Radiation Oncology division has two Acuity simulators (each with cone beam CT capability), three Phillips AcQSim, two GE CT Simulators, and two GE PET-CT for clinical use. One of the CT Simulators has a large bore suitable for CT-scanning large patients. One of the CT simulators is a 16-slice high-speed device, which is also being used for respiratory correlated gated, breath-hold and 4D imaging studies. The PET-CTs are also used for respiratory correlated imaging. Extensive MR and PET imaging capabilities are available in the Division of Diagnostic Imaging.
Radiation Physics Dosimetry Equipment
The Radiation Physics department in the Radiation Oncology division is well equipped for measuring photon, proton and electron absorbed dose with ion chambers, diodes, films and TLDs. The equipment includes several Wellhöffer 3D computerized water phantoms, two Scanditronix 2D computerized water phantoms, and film dosimetry systems including a Vidar film scanner and multiple Lumisys film scanners and film scanning software, an assortment of ion chambers and diodes, water equivalent plastic phantoms, anthropomorphic phantoms and a TLD reader.
