Abstract
A composite scan pattern for ultrasound imaging includes a linear or curved linear scan pattern and one or more sector scan patterns. The sector scan patterns abut the linear or curved linear scan pattern along its boundaries to form the composite scan pattern. The linear or curved linear scan pattern can be steered to a desired angle .theta. for obtaining a high quality image. The sector apertures can be reduced in width and the linear scan pattern can be increased in width for imaging at shallow depths. The composite scan pattern provides a wide field of view for both shallow imaging and deep imaging.
