Figure 9From: Finite volume analysis of temperature effects induced by active MRI implants: 2. Defects on active MRI implants causing hot spots Various hot spot powers P hs . Varying the hot spot power leads to an increasing critical volume up to more than 300 mm3. For power losses greater than 100 mW the tissue temperature exceeds the boiling point of water. This high temperature is reached within a few ms (see Additional file 1 and Additional file 2).Back to article page
