摘要： Techniques for correcting measurement artifacts in MR thermometry predict or anticipate movements of objects (e.g. a thermal treatment device) and/or movements of the patient (e.g. respiratory motion) in or near an MR imaging region that may potentially affect a phase background and then acquire a library of reference phase images corresponding to different phase backgrounds that result from the predicted movements. For each phase image subsequently acquired, one reference phase image is selected from the library of reference phase images to serve as the baseline image for temperature measurement purposes. To avoid measurement artifacts that arise from phase wrapping, the phase shift associated with each phase image is calculated incrementally, that is, by accumulating phase increments from each pair of consecutively scanned phase images.

摘要： Techniques for PRF temperature measurement and correction in long-term MR thermometry utilize a known temperature distribution in an MR imaging area as a baseline for absolute temperature measurement. Phase shifts that arise from magnetic field drifts are detected in one or more portions of the MR imaging area, facilitating correction of temperature measurements in an area of interest. In order to perform the correction, the phase error determined from a region that experienced a known or clinically insignificant temperature change is extrapolated to the area of interest, e.g. by a polynomial fit. In addition, image registration may be performed to account for object motion an/or deformation.
摘要翻译：用于长期MR测温中PRF温度测量和校正的技术利用MR成像区域中已知的温度分布作为绝对温度测量的基线。在MR成像区域的一个或多个部分中检测出由磁场漂移产生的相移，有助于校正感兴趣区域中的温度测量。为了执行校正，从经历已知或临床上不显着的温度变化的区域确定的相位误差被外推到感兴趣的区域，例如，通过多项式拟合。此外，可以执行图像配准以解决物体运动和/或变形。

摘要： Apparatus for producing multiple image slice data responsive to incident radiation passing through an object. The apparatus includes a detector array, having a plurality (p), of parallel rows of detector elements, which receive said incident radiation and generate signals in response thereto, each of which rows is characterized by a width, measured in a direction perpendicular to a long dimension thereof; and signal processing circuitry, which receives signals from the detector elements and which combines the signals in a first combination mode and in at least m additional combination modes. In the first combination mode, the circuitry forms a set of n groups of rows, each such group of rows having an effective group width substantially equal to the effective group width of each of the other groups. In each of the m additional combination modes, the circuitry forms different sets of n groups of rows, each such set having a different effective group width common to all groups in the set. The value of p is less than or equal to the sum n + 2(m - 1).
