摘要：
According to some aspects, a low-field magnetic resonance imaging system is provided. The low-field magnetic resonance imaging system comprises a magnetics system having a plurality of magnetics components configured to produce magnetic fields for performing magnetic resonance imaging, the magnetics system comprising, a B0magnet configured to produce a B0field for the magnetic resonance imaging system at a low-field strength of less than .2 Tesla (T), a plurality of gradient coils configured to, when operated, generate magnetic fields to provide spatial encoding of magnetic resonance signals, and at least one radio frequency coil configured to, when operated, transmit radio frequency signals to a field of view of the magnetic resonance imaging system and to respond to magnetic resonance signals emitted from the field of view, a power system comprising one or more power components configured to provide power to the magnetics system to operate the magnetic resonance imaging system to perform image acquisition, and a power connection configured to connect to a single-phase outlet to receive mains electricity and deliver the mains electricity to the power system to provide power needed to operate the magnetic resonance imaging system. According to some aspects, the power system operates the low-field magnetic resonance imaging system using an average of less than 1.6 kilowatts during image acquisition.根據一些態樣，本發明提供一種低場磁共振成像系統。該低場磁共振成像系統包括具有經組態以產生用於執行磁共振成像之磁場之複數個磁性組件之一磁性系統，該磁性系統包括：一B0磁鐵，其經組態以依小於.2特斯拉(T)之一低場強度產生用於該磁共振成像系統之一B0場；複數個梯度線圈，其經組態以在被操作時產生用以提供磁共振信號之空間編碼之磁場；及至少一射頻線圈，其經組態以在被操作時傳輸射頻信號至該磁共振成像系統之一視場且回應於自該視場發射之磁共振信號；一電源系統，其包括：一或多個電源組件，其經組態以將電力提供至該磁性系統以操作該磁共振成像系統以執行影像獲取；及一電源連接件，其經組態以連接至一單相插座以接收市電且將該市電遞送至該電源系統以提供操作該磁共振成像系統所需之電力。根據一些態樣，該電源系統在影像獲取期間使用小於1.6千瓦之一平均值操作該低場磁共振成像系統。
