Physics of Ultrasound Imaging

Resolution . Image resolution is divided into axial, lateral, elevational, and temporal components ( Figure 2.3 ). Axial resolution is the ability to differentiate two objects along the axis of the ultrasound beam and is the vertical resolution on the screen. Axial resolution depends on transducer frequency.. In a direct imaging mode, the axial resolution and lateral resolution are intertwined and with a change in one affects the other. Let us consider a classical experiment of changing the aperture diameter. In this case, when the lateral resolution decreases, the axial resolution decreases (and vice versa). However, in indirect imaging mode, the.

The ability of an ultrasound system to dis-tinguish between two points at a particular depth in tissue, that is to say, axial resolution and lateral resolution, is determined predomi-nantly by the transducer. resolution is high when the spatial pulse length is short. Spatial pulse length is the product of the number of cycles in a pulse of.. The Airy Disk and Lateral Resolution.. This technique has the advantage of degrading both lateral and axial resolution in a linear manner, while numerical aperture changes affect axial resolution quadratically. In either case, the confocal microscope retains its optical sectioning capabilities and characteristic sampling flexibility..
