A schematic MRI acquisition budget is repeated line time. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

One line has a checked time

One acquisition line takes 8 s in this schematic scan.

Repeated lines give scan time

For 3 lines, the total time is 24 s. This is acquisition scheduling only, not image reconstruction.
