MAGNETIC RESONANCE IMAGING RECEIVE COIL WITH REDUCED RADIATION ATTENUATION

摘要

The invention provides for magnetic resonance antenna (100), wherein the magnetic resonance antenna is a surface coil and is a receive coil. The magnetic resonance antenna comprises one or more antenna elements (104, 404). The magnetic resonance antenna further comprises a preamplifier (402) for the antenna element and a coil former (106) for supporting the antenna element. The coil former is formed from a porous material. The antenna is divided into an irradiation zone (204) and at least one reduced radiation zone (202, 206). The preamplifier for each of multiple antenna elements is located within the at least one reduced radiation zone. The multiple antenna elements are located at least partially within the irradiation zone. The coil former has a perimeter, wherein the irradiation zone extends continuously from a first edge (208) of the perimeter to a second edge (210) of the perimeter. The first edge and the second edge are opposing edges.
