250 MHz Continuous Wave Nitroxide Imager
Imaging system for electron paramagnetic resonance, designed and constructed in our laboratory. This includes the low frequency (250 MHz) imager and LabView-based data acquisition system. The diameter of homogeneous volume (DHV), with a field deviation of less than 40 ppm, is about 2 cm.
Pulse & Continuous Wave 250 MHz Imager
Low frequency EPR system for rat/rabbit imaging. In a field of 90 G, it shows a very high homogeneity of the magnetic field of 3.6 milligauss over the 15 cm diameter volume. Continuous wave operation is controlled by LabView system. Pulse acquisition is controlled by SpecMan4EPR Im! console.
Human Size 250 MHz Imager
This is our largest imager with a coil outer diameter of 81'' and 30 cm DHV. This imager has Rapid Scan and continuous wave imaging capabilities.
Precision X-ray (New Branford, CT) X-RAD 225 Image Guided Biologic Irradiator able to deliver 225 kVp x-rays at up to 8 Gy/min and with a maximum dose gradient (d80-20) of 0.2 mm, cone beam CT capable. Targets as small as 1.5 mm can be irradiated with this system and Intensity Modulate Radio Therapy (IMRT) delivery is intended with CBCT target definition. The system is the production version of the small animal irradiation system developed at the Princess Margaret Hospital under the guidance of Prof. David Jaffray.
Philips RT250 X-ray generator (125-250kVp) for non-image guided irradiation. Dose rate is determined by a combination of tube current and geometry, and ranges from 0.1 to 8 Gy/min.
Varian E-12 EPR spectrometer with an ES102 century bridge and TE102 and TM011 cavities.
Currently under construction
