Temperature mapping of particles during aseptic processing via magnetic resonance imaging

Different Magnetic Resonance Imaging (MRI) techniques for temperature measurement of particles undergoing aseptic processing were studied. A variable flip angle gradient echo sequence was initially tested. With this sequence T1 maps were obtained from two images acquired in sequence with a total imaging time of approximately 25 seconds. With a T1 vs temperature calibration, temperature determinations were possible. Reasonable results were obtained with phantoms at room temperature, but temperature maps of potato cylinders being heated by water did not follow the expected trend of heat penetration from the outside to towards the inside of the potato.
