Abstract
An apparatus for assembling a magnetic resonance imaging (MRI) coil array using separable imaging coil elements and a cable holder for connecting the imaging coil elements to the MRI scanner. Each imaging coil element has a plug shaped connector, which is used for separably connecting to a mating receptacle interface on the cable holder. Each cable holder is pre-formed for a particular anatomy and has receptacle interfaces that are located for optimal placement of imaging coil elements. Ultra-low input impedance preamplifiers are used for minimizing interaction between imaging coil elements. This gives users greater freedom in optimizing position of individual imaging coil elements, as overlapping of adjacent coil elements is not required. Imaging coil elements from one coil array can be easily removed and used in assembling a different coil array.
