Selenium Valley X-ray Laboratory

We conduct most of our X-ray and ionizing radiation experiments in the Selenium Valley X-ray Lab.

The lab has the following pieces of equipment:

  1. two shielded X-ray booths with modern high frequency X-ray generators
  2. one real-time a-Se flat panel detector
  3. a mono-energetic X-ray generator for investigating single X-ray photon response of photodetectors
  4. a 337 nm, 1.6 MW nitrogen laser that is used to investigate the spatial and temporal charge trasport properties of selenium

X-Ray light valve laboratory and clean room

The X-ray light valve (XLV) facility is made up of the XLV laboratory and the XLV area in the adjacent clean room. This facility contains all the equipment required to design, develop and test the XLV devices and readout system.

The clean room provides the controlled environment and equipment required for the XLV fabrication process, including the following:

  1. a spin coater
  2. u/s cleaner
  3. ultrapure water system
  4. UV A/B cure source
  5. vacuum chamber
  6. spacer distributor

The laboratory houses the design and test equipment for the system, including an X-ray booth used to measure the X-ray imaging performance of these systems such as sensitivity, MTF and DQE.

Electronics laboratory

Our electronics laboratory contains all the equipment required to design, evaluate and test electronic circuitry. We have special equipment required to evaluate the physical properties of Selenium and other photoconductors, as well as nanoparticle contrast agents. This equipment includes the following:

  1. function generators
  2. lasers
  3. ultraviolet, visible and near-infrared spectrometer
  4. probe stations
  5. lock in-amplifiers
  6. multichannel analyzers
  7. electron microscope
  8. fluorimetre
  9. particle sizer

Imaging Research Centre for Cardiac Intervention

The XMR system at the Imaging Research Centre for Cardiac Intervention (IRCCI) contains a digital biplane X-ray system and an interventional magnetic resonance imaging (MRI) system that are adjacent to each other.

Clinician-scientists use this facility to treat patients with medical conditions that will benefit from a combination of high-resolution real-time X-ray images providing the guidance of minimally invasive interventional devices and MRI images that reveal soft tissue anatomy and function.

We have a system that transfers the patient between the X-ray and MRI suites. This allows us to use both imaging modalities during an intervention.

Imaging scientists in our group use this system to investigate methods to reduce the X-ray exposures of patients and operators, and to conduct experiments to test new methods to improve the diagnostic quality of X-ray images. These facilities are important, because few places possess clinical equipment available for testing and deploying new research ideas.
