Abstract

The invention provides a receiving antenna assembly and a magnetic resonance device. The receiving antenna assembly comprises at least one receiving antenna; the receiving antenna comprises a base part and two antenna units; one end of each of the two antenna units is respectively connected with the base part, the two antenna units form a first annular body with a first opening, and the other end of each of the two antenna units is oppositely arranged and is spaced by a first preset distance to form the first opening, wherein each antenna unit is of a flexible structure. Through the configuration, the first annular body formed by the two antenna units forms the dipole antenna, the dipole antenna is simple in structural form, a concentrated tuning part is not needed to be arranged except the base part to adjust the resonant frequency of the dipole antenna, and the problem that an existing flexible receiving coil adopts a tuning capacitor and is prone to being bent and damaged is solved. Furthermore, the antenna units are of the flexible structure so that the whole receiving antenna is easy to bend and good in wearing comfort, and the workflow is simplified.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a receiving antenna assembly and a magnetic resonance device. Background technique [0002] In MR (Magnetic Resonance Imaging, Magnetic Resonance Imaging) or PET-MR (PositronEmission Tomography-Magnetic Resonance Imaging, Positron Emission Tomography-Magnetic Resonance Imaging, Positron Emission Tomography-Magnetic Resonance Imaging) system, there is a radio frequency coil, the radio frequency coil includes a transmitting coil and a receiving coil, Or double as a radio frequency coil for transmitting and receiving. [0003] The independent receiving coil includes a flexible receiving coil for wrapping and sticking to the human body. However, the existing flexible receiving coil adopts the traditional antenna structure and circuit structure, which is large in size and has a certain weight. It needs to be used during the scanning process. The strap fixes the flexible rec...
