Abstract
In a method for determining a minimum possible echo time for a radio-frequency coil used in a magnetic resonance scanner, magnetic resonance signals are acquired with the radio-frequency coil in a magnetic resonance measurement of a free induction decay at fixed time intervals, the minimum possible echo time being determined by evaluating the time series of magnetic resonance signals as the instant from which an exponential signal decay was measured.

A method for determining a minimum possible echo time in a radio-frequency coil in a magnetic resonance scanner, comprising:
- operating the magnetic resonance scanner to detect magnetic resonance signals with said radio-frequency coil in a magnetic resonance measurement of free induction decay at fixed time intervals;
- providing said magnetic resonance signals to a processor and, in said processor, automatically evaluating said magnetic resonance signals detected at said fixed time intervals to determine the minimum possible echo time as a point in time from which an exponential signal decay was detected by said radio-frequency coil;
- and
- in said processor, generating a control protocol, that embodies said minimum possible echo time, and emitting said control protocol as an electrical control signal for operating said magnetic resonance scanner.
