  • Publication number: 20100113929
    Abstract: Since high-frequency ultrasound provides the advantage of high spatial resolution, it has been applied to relevant fields of medical imaging research. Due to a lack of high-frequency ultrasonic transducer with array structure, the high-frequency ultrasonic transducer must be performed in a fixed depth of focus during scanning. A swept scanning method is typical for flow estimation. However, this method cannot provide the precise flow estimation within the irregular-shaped object, because the focal zone of the above-mentioned transducer just covers a specific depth of focus and the outside the focal area corresponds poor signal to noise ratio. To resolve this problem, the present invention provides a skin scanning method, which can move the transducer along a scanning route parallel to the contour of the irregular-shaped object during scanning. The scanning results show that the skin scanning method improves the accuracy of flow estimation.
