Signa Teledyne Surface Coil Test (Signa Rev 8.2.5 and Higher) 
The Surface Coil Test is a Signal-to-Noise measurement test with improved Tool Gage R&R. The Test allows the user to make a definite pass/fail decision on the GE 1.5T CTL Array Coil, M1087CT. The Test allows the operator to input comments and customer observations of coil performance prior to test execution. This information assists in data collection and Test usage feedback to GE MR Headquarters.

SIGNA SURFACE COIL TEST FOR THE USA I CTL COIL
The Surface Coil Test for the USA Instruments Quad CTL Array is a Signal-to-Noise measurement test with improved Tool Gage R&R. The Test allows the user to make a definite pass/fail decision on the GE USA Instruments 1.5T Quadrature CTL Array Coil, M1087SP or the earlier version, E8800P.
