Abstract: The invention relates to a temperature distribution determining apparatus (21) for determining a temperature distribution within an object, to which energy is applied, by using an energy application element (2). A first temperature distribution is measured in a first region within a first temperature range and a model describing a model temperature distribution in the first region and in a second region depending on modifiable model parameters is provided. A second temperature distribution is estimated in the second region within a second temperature range, while the energy is applied to the object, by modifying the model parameters such that a deviation of the model temperature distribution from the first temperature distribution in the first region is minimized. This allows considering the temperature dependence of the model parameters within the second temperature range, while estimating the second temperature distribution, thereby improving the accuracy of the estimation of the second temperature distribution.

Abstract: The invention relates to a temperature distribution measuring apparatus for measuring a temperature distribution within an object caused by heating the object. A temperature distribution measuring unit (13, 71) measures the temperature distribution in a measurement region within the object, while the object is heated, and a temperature measurement control unit (22) controls the temperature distribution measuring unit such that the measurement region is modified depending on the measured temperature distribution, in order to measure different temperature distributions in different measurement regions. This allows, for example, modifying the measurement region depending on an actually measured temperature distribution such that in the modified new measurement region the measurement of the temperature of the object can be continued, if the temperature actually measured in the current measurement region is too high for being accurately measured, thereby extending the time period in which a temperature distribution of the object can be measured.

Abstract: The invention relates to an apparatus for determining a relation between a surface motion of a body (BD) and an object motion of an object (OB) within the body (BD). The apparatus comprises a first sensing unit configured to acquire a first position signal indicative of a position of a first element placed at the location on the surface of the body with the surface motion; a second sensing unit configured to acquire a second position signal indicative of a position of a second element attached to an interventional device and placed on or in the object, wherein the first position signal and the second position signal are acquired during a given duration synchronously; and a third unit for calculating the relation between the surface motion and the object motion based on the first position signal and the second position signal. The invention also relates to a corresponding method for determining the motion relation.

Abstract: 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.

Abstract: A method and an apparatus or needle visualization enhancement in ultrasound (US) imaging includes a Radon transform (RT) unit configured to perform RT on a sequence of frames to detect line features in the frames, where a frame includes US radio-frequency (RF) data obtained during monitoring the insertion of a needle into a subject or an US image reconstructed from the RF data. Further, a false needle feature removing unit is configured to remove line features which remain substantially stationary among the frames as false needles while locating a line feature which extends among the frames as the needle; and an overlaying unit is configured to overlay the location of the line feature as the needle on an US image of a frame to produce an enhanced image to be displayed.
