Using this model, hot and cold spots in the products may be simulated to test appropriate microwave treatment control strategies. A further development of this approach, being one-of-a-kind to date, describes a feedback-control loop in the simulation which helps optimising microwave processes by ensuring minimal time/temperature treatments and uniform temperature distributions. Thus microwave power pulse programs can be developed and tested in a model before being implemented in a real microwave system. Validation of the model was performed using non-invasive
magnetic resonance imaging (MRI)
