摘要： The invention relates to an energy application system for applying energy to an object like a tumor. The system comprises several energy application devices (3) to be introduced into the object, which are adapted to receive electromagnetic radiation (2) and to generate heat depending on a frequency distribution of the received electromagnetic radiation, wherein the dependency of the heat generation on the frequency distribution of the electromagnetic radiation is different for different energy application devices. The system further comprises an electromagnetic radiation providing device (1) for providing electromagnetic radiation having a certain frequency distribution for stimulating the energy application devices to generate a predefined heat pattern. Since the dependency of the heat generation on the frequency distribution of the electromagnetic radiation is different for different energy application devices, even a relatively complexly shaped predefined heat pattern can relatively easily be generated by selectively addressing the energy application devices accordingly.
摘要翻译：本发明涉及一种将能量施加到像肿瘤的物体上的能量施加系统。该系统包括若干能够被引入到物体中的能量施加装置（3），其适于接收电磁辐射（2）并且根据所接收的电磁辐射的频率分布产生热量，其中发热的依赖性对于不同的能量施加装置，电磁辐射的频率分布是不同的。该系统还包括电磁辐射提供装置（1），用于提供具有一定频率分布的电磁辐射，用于刺激能量施加装置以产生预定义的加热模式。由于对于不同的能量施加装置，发热对电磁辐射的频率分布的依赖性是不同的，所以即使通过相应地选择性地寻址能量施加装置也可以相对容易地产生相对复杂形状的预定义热图案。

摘要： The invention relates to a magnet assembly for an MRI system with an improved RF screen. The RF screen is located between an RF coil assembly and a gradient coil assembly and comprises multiple layers of a screening foil. The screening foil comprises a dielectric foil and a plurality of conductive patches which are applied to a first side of the dielectric foil. By wrapping up the screening foil several times an RF screen comprising a plurality of capacitors is created, which effectively shields RF radiation from the gradient coil assembly. Further the shape and arrangement of the conductive patches is chosen such that the flow of eddy currents in the conductive patches caused by a gradient magnetic field is reduced.

摘要： The invention relates to a system for controlling a superconducting coil (6) with a magnetic persistent current switch (7). The magnetic persistent current switch (7) is used for switching the superconducting coil (6) between a persistent mode and a ramp mode, respectively. The system further comprises a heat exchanger (10) configured to disperse heat to a cryocooler (3), a loop tube (13) configured to enable flow of coolant to transfer thermal energy generated by the magnetic persistent current switch (7) to the heat exchanger (10), and a thermal switch (9) comprising a valve (14) integrated with the loop tube (13) between the magnetic persistent current switch (7) and the heat exchanger (10), the valve (14) comprising a valve body (15) with and inlet (16) and an outlet (17) with which the valve body (15) is connected to the loop tube (13), a movable shaft (18) which is arranged inside the valve body (15) and which comprises a permanent rod magnet (19), a latching arrangement (20) which comprises a permanent magnet (21), and a solenoid (22), wherein the shaft (18) is movable between a closed position in which the shaft (18) effects the closing of the inlet (16) or the outlet (17) of the valve body (15) and therefore no flow of coolant through the valve body is allowed, and an open position in which the inlet (16) and the outlet (17) of the valve body (15) are open and therefore flow of coolant through the valve body (15) is allowed, the solenoid (22) is arranged relative to the shaft (18) in such a way that by applying a current pulse with a first polarity to the solenoid (22) the shaft (18) is moved to the closed position, and by applying a current pulse with a second polarity to the solenoid (22), the second polarity being opposite to the first polarity, the shaft (18) is moved to the open position, and the latching arrangement (20) is arranged relative to the shaft (18) in such a way that the magnetic force acting from the permanent magnet (21) of the latching arrangement (20) to the permanent magnet (19) of the shaft (18) forces the shaft (18) to stay in the closed position or in the open position, respectively, as long as no current pulse is applied to the solenoid (22) for switching the shaft (18) from the closed position to the open position or vice versa, respectively. In this way, a cooling system is provided that allows the temperature of the magnet persistent current switch (7) to rise and fall as desired within a short period of time, without straining the cooling system for the superconducting coil (7).
