摘要： The invention relates to a temperature distribution determining apparatus for determining a temperature distribution within an object caused by applying energy to the object. A temperature distribution measuring unit (6, 7) measures a spatially and temporally dependent first temperature distribution in the object (3), while the energy is applied to the object (3) such that the object (3) is heated to a temperature within a first temperature range, and a temperature distribution estimating unit (5) estimates a spatially and temporally dependent second temperature distribution in the object (3) within a second temperature range, which is different to the first temperature range, based on the spatial and temporal dependence of the measured first temperature distribution. Since temperature distributions can be obtained not only in the first temperature range, but also in the second temperature range, the overall temperature range, in which the temperature distribution can be determined, can be increased.

摘要： A therapeutic system comprises a therapy module to direct a therapeutic action, e.g. focused ultrasound or RF energy to a target. An imaging module such as an magnetic resonance examination system generates image information of a therapy region that includes the target. By way of a motion analysis module a motion vector field is derived from the image information of the therapy region. A control module controls the therapy module on the basis of the motion vector field. Notably, on the basis of the motion vector field an accurate temperature distribution is derived from magnetic resonance signals and the motion vector field. Also magnetic resonance elastography data may be employed to improve the accuracy of the temperature distribution.

摘要： In the CT imaging of non-homogeneously moving objects such as the heart or the coronary vessel tree, there is a problem that different parts of the objects are at rest at different points in time. Thus, a gated reconstruction with a globally selected time point does not yield a sharp image of such objects. According to the present invention, a motion of the object is estimated, describing the motion of selected regions of these objects. Then, on the basis of the estimated motion, time points are determined, where these areas have minimal motion. Then, an image is reconstructed, wherein the data from which the respective regions are reconstructed, correspond to the respective time points, where the regions have minimal motion. Due to this, an improved image quality may be provided.

摘要： A diagnostic imaging system, notably a magnetic resonance imaging system comprises a receiver antenna for picking-up magnetic resonance signals and an ultrasound probe for receiving ultrasound echoes. A reconstruction unit is arranged to reconstruct a diagnostic image from the magnetic resonance signals and the ultrasound echoes in particular, the magnetic resonance image and ultrasound images are registered in a common reference frame and geometric distortions in the ultrasound image are corrected on the basis of the magnetic resonance image. Different tissues types are distinguished in the magnetic resonance image and corrections are made for differences between ultrasound sound velocities in these tissue types. Further, information contained in the magnetic resonance signals can be displayed in combination in the ultrasound echoes.
