Embodiment Construction

[0027] The scan conversion method and device for color ultrasound imaging according to the present invention will be described below with reference to the accompanying drawings, taking ultrasound diagnosis as an example. It should be noted that the method and device according to the present invention are not limited to the field of medical ultrasound imaging, and can be applied to various fields related to ultrasound imaging, such as in fluid kinematics research and hydraulic pipeline detection.

[0028] image 3 It is a schematic block diagram of a typical ultrasonic diagnosis system, which includes the blood flow DSC module referred to in the present invention. The blood flow DSC module converts the blood flow signal into a format that can be displayed by a CRT or LCD. Before introducing the method flow of the color DSC according to the present invention, in order to facilitate the understanding of improvements, the traditional DSC method flow is firstly introduced.

Abstract

The invention provides a scanning conversion method used in color ultrasound imaging, which comprises a storage step, a coordinate conversion step, and an interpolation step; wherein, the interpolation step comprises a neighbor point inner interpolative substep, an aliasing determination substep and an echo data revision substep. The interpolation treatment is carried out on neighbor point ultrasound echo data by the neighbor point inner interpolative substep to obtain the echo data of an interpolation point. The aliasing determination substep is used for deciding whether the aliasing occurs on the neighbor point ultrasound echo data. If the aliasing occurs, firstly, the echo data revision substep is implemented, and then the neighbor point inner interpolative substep is implemented; if the aliasing does not occur, the echo data revision substep is omitted, the neighbor point inner interpolative substep is directly implanted. The method can weaken noise caused by aliasing in the colorultrasound imaging system. In addition, the calculated amount and the storage room spent by the interpolation algorism used by the method are all less. The invention also provides a device which usesthe method.

Description

technical field [0001] The invention relates to a scan conversion method for color ultrasound imaging, more particularly to a scan conversion method for a medical color ultrasound diagnosis system. The invention also relates to a device employing the method. Background technique [0002] Ultrasonic diagnostic equipment uses the propagation of ultrasonic waves in the human body to obtain ultrasonic characteristic information of human tissue and organ structures, and form various imaging modes for display. During actual clinical examination of patients, the information is displayed on a cathode ray tube (cathode ray tube; CRT) or a liquid crystal display (Liquid Crystal Display; LCD) in real time. [0003] The imaging of the geometric shape of human tissue structure is generally displayed in B (Brightness) mode. In this mode, the brightness displayed on the CRT or LCD dot matrix represents the amplitude of the ultrasonic echo. In B mode, images of some tissue motions (such ...
