Which time interval refers to the duration from a gradient's minimum to maximum field difference?

The time interval that describes the duration from a gradient's minimum to maximum field difference is known as Rise Time. Rise Time specifically measures how quickly the gradient can change from its lowest point to its highest point, which is crucial for applications like MRI where rapid changes in magnetic fields are required for effective imaging. A shorter Rise Time means the gradient can switch faster, allowing for better spatial resolution and improved imaging quality.

While Amplitude refers to the strength or intensity of the gradient, and Slew Rate pertains to the speed at which the gradient's strength changes over time, neither of these directly addresses the specific interval between the minimum and maximum field difference. Field Duration, on the other hand, relates to how long a gradient is maintained at a certain level but does not define the interval from minimum to maximum, making Rise Time the most appropriate choice for this question.
