摘要： A medical apparatus (1100) comprising a magnetic resonance imaging system and an interventional device (300) comprising a shaft (302, 1014, 1120). The medical apparatus further comprises a toroidal magnetic resonance fiducial marker (306, 600, 800, 900, 1000, 1122) attached to the shaft. The shaft passes through a center point (610, 810, 908, 1006) of the fiducial marker. The medical apparatus further comprises machine executable instructions (1150, 1152, 1154, 1156, 1158) for execution by a processor. The instructions cause the processor to acquire (100, 200) magnetic resonance data, to reconstruct (102, 202) a magnetic resonance image (1142), and to receive (104, 204) the selection of a target volume (1118, 1144, 1168). The instructions further cause the processor to repeatedly: acquire (106, 206) magnetic resonance location data (1146) from the fiducial marker and render (108, 212) a view (1148, 1162) indicating the position of the shaft relative to the target zone..

摘要： A computed tomography method and apparatus are provided wherein a radiation source moves circularly relative to an examination zone about an axis of rotation (14). The radiation source produces a cone beam of x-rays and the focal point of this cone beam is switched between at least two positions (23a, 23b) sapced apart from each other and arranged on a line parallel to the axis of rotation to enlarge the reconstructable examination zone parallel to the axis of rotation. Preferably, the image of the examination zone is reconstructed using an iterative reconstruction method, in particular an algebraic reconstruction method or a maximum likelihood method.

摘要： A diagnostic imaging system (8) images a subject at a preselected phase point (46) which occurs in one or more successive pulmonary cycles. A breathing monitor (44) monitors a cyclic physiological parameter in the pulmonary cycle and generates a cyclic pulmonary phase indicative signal. A CT scanner (12) is disposed adjacent an examination region (28) to generate transmission radiation data. A data processor (60) reconstructs an attenuation map (96) from the transmission data by weighting the transmission radiation data such that each of the pulmonary phases contributes substantially equally to the attenuation map.

摘要： The invention relates to a method and a system for the reconstruction of an object function (f(x)) based on projections acquired during the motion of a radiation source on a helical trajectory (17). The method is particularly suited for an n-PI+ acquisition which by definition completely comprises an n-PI and additionally some overscan data from the (n+2)-PI window. According to the method, two sets (∑≤m, ∑>m) of filtered projections are generated from the measuring values and separately back- projected to yield two absorption functions. The first absorption function (f lf (x)) is based on contributions of Radon-planes with at most m intersections with the source trajectory (17), while the second absorption function (f hf (x)) is based on Radon-planes with more than m intersections with the source trajectory (17). The two absorption functions are added to yield the final absorption function (f(x)) of an object in the examination zone. In an approximative version of the method, the sets (∑≤m, ∑>m) of filtered projections are first added and then back-projected.
摘要翻译：本发明涉及一种用于基于在螺旋轨迹（17）上的辐射源的运动期间获取的投影来重建对象函数（f（x））的方法和系统。该方法特别适用于n-PI +采集，其通过定义完全包括n-PI，并且另外还包括来自（n + 2）-PI窗口的一些过扫描数据。根据该方法，从测量值产生两组滤波投影（λ= m，λ> m），并分别反投影以产生两个吸收函数。第一吸收函数（f（x））基于与源轨迹（17）最多m个交点的氡面的贡献，而第二吸收函数（f' （x））基于与源轨迹（17）超过m个交点的氡面。添加两个吸收函数以产生检查区中物体的最终吸收函数（f（x））。在该方法的近似版本中，首先添加滤波投影的集合（λ= m，λ> m）然后反投影。

摘要： Using only projection data in one temporal gating window around a certain target phase point may lead to motion artifacts such as blurred images. By using projection data corresponding to three temporal gating windows, which are slightly shifted with respect to each other but at least partially overlap, motion within the gating window may be estimated and, according to an exemplary embodiment of the present invention, this estimation may be used for improving the image quality. Advantageously, only the projection data inside the at least partially overlapping gating windows are used for reconstruction and motion compensation.
摘要翻译：在某个目标相位点周围的一个时间门控窗口中仅使用投影数据可能会导致运动伪影，如模糊图像。通过使用对应于相对于彼此略微偏移但至少部分重叠的三个时间门控窗口的投影数据，可以估计门控窗口内的运动，并且根据本发明的示例性实施例，该估计可以是用于提高图像质量。有利地，仅将至少部分重叠的门控窗口内的投影数据用于重建和运动补偿。
