摘要：
1. An interface device for interfacing a coil with a magnetic resonance installation, wherein the coil comprises a pair of coil loops configured in a phased array configuration, each of which is designed to receive magnetic resonance signals from a region of interest corresponding to it, while the interface device comprises : (a) a first pre-amplifier for receiving a signal from a first coil loop from a pair of coil loops to create a first amplified signal； (b) a second pre-amplifier for when the signal from the second coil loop from a pair of coil loops to create a second amplified signal； (c) a first splitter functionally coupled to the first pre-amplifier to split the first amplified signal into a right-loop signal that is fed to the first channel output and the first composite signal ； (d) a second splitter functionally connected to a second pre-amplifier for dividing the first amplified signal into a left loop signal, which is applied to the second channel output, and a second component nth signal； (e) a third splitter functionally connected to the first splitter to separate the first composite signal； (f) a fourth splitter functionally connected to the second splitter to separate the second composite signal； (g) a zero-degree combiner functionally connected to the third splitter and a fourth splitter to combine the signals received from them to create a saddle-type coil signal that is applied to the third channel output； and (h) a 180 degree combiner operably coupled to1. Интерфейсное устройство для сопряжения катушки с магнитно-резонансной установкой, при этом катушка содержит пару контуров катушки, установленных в конфигурации с фазированной решеткой, каждый из которых предназначен для приема магнитно-резонансных сигналов из исследуемой области, соответствующей ему, при этом интерфейсное устройство содержит:(a) первый предварительный усилитель для приема сигнала от первого контура катушки из пары контуров катушки, чтобы создавать первый усиленный сигнал；(b)
