A method includes obtaining contrast enhanced image data indicative of scar tissue created by ablation of tissue of interest, quantifying an amount of contrast material for the scar tissue in the tissue of interest, and generating a signal indicative of a recommendation to further ablate the tissue of interest in response to the quantified amount of the contrast material not satisfying a pre-determined threshold.

The method combines different electrolyte solutions having the same solvent. The solution is successively compressed and vaporized at different temperatures and the vapor is successively absorbed by the second solution that exhibits higher negative deviation, at higher temperature. The absorption heat of each absorber is recovered by the next evaporator. The more evaporator-absorber pairs that are used the higher the temperature lift or the created pressure ratio. Finally the vapor returns to the first solution at high temperature. Electrolyte is dissolved and rejected from each solution to achieve total heat recovering and the very high efficiency of the cycle. Gas absorption is suggested instead of solvent vapor.

The present invention relates to a triple-effect absorption chilling apparatus adopting a structure of an anti-parallel cycle in which an absorber and a first regenerator are connected in series, a second regenerator and a third regenerator are connected in parallel with the first regenerator, and the solution through the second regenerator and the third regenerator is returned to the absorber. Therefore, according to the present invention, it is possible to improve efficiency by acquiring a higher coefficient of performance than conventional absorption refrigerators, and to reduce energy consumption.
