Abstract
An ultrasonic photographing method of skull is disclosed, which detects and creates image on skull blood vessels, and the blood of the blood vessels have a plurality of micro bubbles from contrast agent injection. The method includes the following steps: (1) sending ultrasonic emitting signals which have band-shape bandwidth to internal skull vessels; (2) detecting echo signals from micro bubbles; (3) proceeding spectrum analysis on echo signals for low frequency echo, in which bandwidth is similar to emitting signal; (4) calculating the direction, position and depth of the micro bubbles from low frequency echo, and creating a vessel image.
