An ultrasonic diagnostic imaging system produces 3D images by scanning a target volume with a mechanical probe, which scans the target volume by sweeping the scan plane of an array transducer through the target volume in an elevation direction. The array transducer has two selectable focal depths, and a plurality of scan planes of image data are acquired with a far field focus, and a plurality of scan planes of image data are acquired with a near field focus. The scan planes acquired with the far field focus are separated in the elevation direction by a distance which satisfies a spatial sampling criterion in the far field, and the scan planes acquired with the near field focus are separated in the elevation direction by a distance which satisfies the spatial sampling criterion in the near field, resulting in fewer scan plane acquisitions with the near field focus that the number of scan plane acquisitions with far field focus and hence an improved volume rate of display.
