Abstract
A radio frequency (RF) receiver assembly (100) for use in a magnetic resonance imaging (MRI) system is described. The receiver assembly (100) comprises a primary resonant circuit (101) coupled to a preamplifier (106) via capacitive coupling, and a secondary resonance circuit (104) comprising of at least one inductor (104a) coupled between a first switch (103) and the capacitive coupling. The first switch (103) is circuited between the primary (101) and the secondary (104) resonant circuits, and the preamplifier (106).
