The k -space simulation. A gray scaled image showing the simulated normalized pressure squared distribution of a single segment of the hyperthermia phased array using the k-space computational method. The results are shown for the central transverse plane of the 3D prostate model. The image shows a two-layered gray scale photograph for the central plane showing a background layer of the absorption distribution and the normalized squared pressure distribution on top of it while focusing axially 40 mm away from the face of the array.
