Analyzing the cause of the artifact in the ultrasound endoscopes image, the paper presents a digital image process method to remove the artifact.

The design and implementation of coded excitation in ultrasonic endoscope system

The imagining system of ultrasonic endoscope is based on the electronic endoscope and the ultrasonic probe is getting into the body and the target organ through inspect passag.

Ultrasonic Endoscope Imaging System is an important component of the endoscopic ultrasonography system (EUS) which detect the characteristics of the fault histology features of digestive organs through the ultrasonic probe, use ultrasonic echo reception circuit to implement the function of amplify, gain compensation, filtering and A/D converter, output digital signal of the ultrasonic echo.

Result By using 800 general clinical endoscopic images, the precisions and recalls under various conditions, such as single feature, multi-feature fusion and relevance feedback.

This paper presents two feature fusion algorithms of medical image retrieval about endoscopic image based on FCM as follow:first,using color correlogram combining with color texture;second,using color correlogram combining with color histogram.

The method use the Kernel principal component analysis(KPCA) to extract the high order relation nonlinear feature of image pixels, and selects optimal Support Vector Machines(SVM) to perform the endoscopic image recognition.

USB2.0 Interface Design for High-Speed Image Acquisition System of Medical Ultrasonic Endoscope;

0 Specification, a novel method for implementing high-speed image acquisition in medical ultrasonic endoscope by DMA is proposed.
