摘要：
The invention relates to a heat sink parameter determination apparatus for determining a parameter of a heat sink like a blood vessel within an object such as a person (3) by minimizing a deviation between a measured temperature distribution, which has preferentially been measured by ultrasound thermometry, and a modeled temperature distribution, wherein the modeled temperature distribution is modeled based on a provided heat source parameter like the location of an ablation needle (2) and the heat sink parameter to be determined by using a given thermal model. This determination of heat sink parameters, which may be geometric and/or flow parameters, considers the real temperature distribution and is thus based on real heat sink influences on the temperature distribution. This can lead to an improved determination of heat sink parameters and hence to a more accurate temperature distribution which may be determined based on the determined heat sink parameters.
