Figure 6From: MR thermometry characterization of a hyperthermia ultrasound array designed using the k-space computational method Ex vivo MRI hyperthermia. (a) An MRI image of a selected bovine slice showing the focused transducer cross sectional view. (b) The thermal image after driving the transducer for five minutes. The color bar relates relative temperature values in °C. (c) Ex vivo controlled hyperthermia results using MRI thermometry and the switching controller.Back to article page
