The scanner used to capture the cardiac atlas is a Magnetom Avanto scanner installed at the Centre for Advanced MRI at the University of Auckland, New Zealand in 2004.

A scanner in the laboratory

The Siemens Magnetom Avanto scanner.

The scanner is a 1.5 Tesla system and was the first available with Siemens' new Total Imaging Matrix (TIM) technology. It can have up to 76 connected coil elements and 18 independent RF channels that allow for parallel imaging and the ability to capture a full body scan without repositioning the patient. It utilises Siemens SQ-engine Gradient system with AudioComfort that reduces the noise of the scanner by 30dB(A) or a 975 reduction in sound pressure removing the requirement of earphones during the scan. The SQ gradient engines have a maximum gradient of 45/40/40mT/m in the longitudinal, horizontal and vertical direction respectively with a maximum slew rate of 200T/m/s and a minimum rise time of 200µs. The scanner can obtain a Field of View ranging between 0.5-50cm and has a minimum slice thickness of 1mm and 0.05mm in 2D and 3D images.
