摘要： The invention relates to a device for generating X-rays (31). The device has a source (5) for emitting electrons (27) accommodated in a vacuum space (3). The X-rays are emitted by a liquid metal as a result of the incidence of the electrons. The liquid metal flows through a constriction (13) where the electrons emitted by the source impinge upon the liquid metal. The constriction is bounded by a thin window (23), which is made from a material which is transparent to electrons and X-rays and which separates the liquid metal in the constriction from the vacuum space. According to the invention, the constriction (13) has a cross-sectional area which, seen in a main flow direction (X), increases in such a manner that during operation in said direction, a decrease of a flow velocity takes place such that a decrease of a pressure of the liquid metal in the constriction in said direction, caused by viscous flow losses, substantially corresponds with an increase of said pressure in said direction, which is caused by the Bernoulli effect resulting from said increase of the velocity. As a result, the pressure of the liquid metal in the constriction can be maintained at a uniform relatively low level throughout the constriction, so that a uniform and relatively low mechanical load is exerted on the window during operation. In this way, the deformation of the window and the risk of breakage of the window are considerably limited.
摘要翻译：本发明涉及一种用于产生X射线的装置（31）。该装置具有用于发射容纳在真空空间（3）中的电子（27）的源（5）。由于电子的入射，X射线被液态金属发射。液体金属流过收缩部（13），其中由源发射的电子撞击液态金属。收缩线由薄的窗口（23）限定，薄的窗口（23）由对电子和X射线透明的材料制成，并且将收缩部中的液态金属与真空空间分开。根据本发明，收缩部（13）具有从主流动方向（X）看到的横截面积，以这样的方式增加，即在所述方向的操作期间，发生流速的降低，使得由粘性流动损失引起的在所述方向上的收缩部分中的液态金属的压力的降低基本上对应于由所述速度的增加引起的伯努利效应引起的所述方向上的所述压力的增加。结果，收缩部中的液态金属的压力可以在整个收缩部中保持在均匀的相对较低的水平，使得在操作期间在窗口上施加均匀且相对较低的机械载荷。以这种方式，窗口的变形和窗口破裂的风险受到相当的限制。

摘要： The invention relates to electrophysiology catheter systems and their use, such as in an MRI environment, and in particular to analysis of electric signals from such. An electrophysiology (EP) catheter with a plurality of electrically isolated electrode segments arranged in longitudinally spaced bands around the catheter is used to detect electric signals. A workstation receives the electrical signals which are then processed by a processing unit. Electric signals from electrode segments can be used to determine roll angle information of the catheter in relation to patient anatomy by determining signals from electrode segments in contact with tissue. Also, electric signals can be used to extract a reference signal that can be used to correct for gradient induced artefacts.
