摘要： The invention relates to a coil arrangement comprising at least one transmitting coil for generating a primary magnetic field; and a plurality of measurement coils; wherein the at least one transmitting coil (408, 409) and the plurality of measurement coils (410, 411) are arranged in such a way that the flux curve of the primary magnetic field generated by a transmitting coil (409) among said at least one transmitting coil (408, 409) passes into and out of a first measurement coil (410) among said plurality of measurement coils (410, 411), the first measurement coil being the coil closest to the transmitting coil. By enabling the flux of the primary magnetic field to pass into and out of a first measurement coil, the signal induced on the first measurement coil by the positive and negative flux can be compensated, resulting in a reduction of the signal strength of the induced signal on the measurement coil and the signal dynamic range.

摘要： The invention relates to a method and apparatus for monitoring an object of interest (100). According to the invention, a cushion (104) is inflated such that the inflated cushion extends inwards to envelop the object of interest (100), whereupon the pressure exerted on the object of interest (100) by the inflated cushion (104) is measured and a signal is output to stop inflating when the pressure reaches a predefined threshold. After that, the volume of the inflated cushion is measured and the size of the object of interest (100) is derived from the volume of the inflated cushion (104). In this way, the invention can keep the object of interest still during monitoring. Furthermore, the size of the object of interest can be used for imaging reconstruction to improve the quality of reconstructed images.

摘要： This invention relates to a method and device for calibrating the offset of an imaging system. The core idea of the invention is to place a reference object in the measurement chamber of the imaging system, measure the signals associated with the reference object at different points of time, calculate the merit function based on changes of the parameters representing the electromagnetic property of the reference object, and derive an optimal set of offset data that minimizes the value of the merit function for compensating the offset of the system in subsequent image reconstructions. In one embodiment, the invention uses a reference object comprising a non-conductive envelope and a cavity which can be filled with a conductive fluid and emptied, and in this way reduces the imaging interference caused by the reference object during monitoring.
