Abstract
Transcranial imaging must overcome the adverse effects of scattering and attenuation in the skull bone. Significant image degradations stem from defocusing of the ultrasonic field, causing loss of spatial resolution and lower penetration depth due to a small signal-to-noise ratio. To compensate for the refraction and multiple reflections of ultrasound caused by the skull, we developed a new transcranial imaging technique using small-aperture ultrasonic phased arrays.
