Fig. 4From: A device for the controlled cooling and freezing of excised plant specimens during magnetic resonance imagingImaging artifacts created by the flow of ethylene glycol in the coolant chamber. Imaging artifacts (within highlighted box) (a) were eliminated from the sample chamber view by modifying the device to include material fins to divert the coolant flow from the imaged volume along the longitudinal axis of the device. As a result, clear images of V. macrocarpon (b) bud samples were obtained. Scale bar equals 5 mmBack to article page
