The input data format in a single-sector or multi-sector scanner imaging system is chosen such that angulated scan lines intersect a lateral line at equal increments, and along the scan lines the echo signal is sampled at different rates whereby sampling points are along parallel raster lines. Echo signals (1, 2, 3) from successive scan lines are stored (29, 31) in adjacent columns of a row-column oriented digital memory (30A-30D, 32). Echo data is read out (34A-34D, 35, 36, 37, 38) of memory row by row at a variable rate to convert the read-out data back to sector geometry. The image is displayed in real time on a cathode ray tube.
