In this work we reported a design and principle of a three-axis digital output gyroscope-based intelligent ultrasonic diagnostic navigation system. The proposed system provided a real-time intelligent navigation for ultrasound scanning and clinical puncture by transmitting and recording the positional relationship of ultrasound probe and corresponding body structure in real time through network. This system could provide technical support for remote ultrasonic medical consultation.

In this work we reported the design and build of a nine-axis digital output gyroscope-based percutaneous puncture ultrasonic navigation system. The proposed system includes three types of sensing elements: three-axis gyroscopes, three-axis accelerometers and three-axis magneto-resistivemagnetometers. Gyroscopes are used to measure the absolute angular rate of the carrier. Theaccelerometers are used to determine the initial attitude of system and to correct for gyroscope drift in the tilt angles (pitch, roll) determination. The magnetometers are used to determine the initial alignment in heading and to correct for gyroscope drift in the heading. The nine-axis digital output gyroscope combined with ultrasound probe can accurately collect triaxial angle changes of the ultrasound probe, Then guide the orientation of the puncture needle in the ultrasonic navigationpercutaneous puncture. The system can increase puncture accuracy.

Hemorrhagic Lesion

Hemorrhage into areas of periventricular leukomalacia may occur and range in size from microscopic to massive. Hitherto, the definitive diagnosis has been made only at autopsy. A case is described in which the diagnosis of hemorrhagic periventricular leukomalacia was made antemortem by real-time ultrasound scanning and confirmed at autopsy. Periventricular/intraventricular hemorrhage, a more common hemorrhagic lesion, may extend into periventricular white matter in a location ventral and medial to hemorrhagic periventricular leukomalacia. Real-time ultrasound scanning is a safe and reliable means of defining the topography of these two hemorrhagic lesions and, thereby, of suggesting the correct diagnosis.

Problems in the process of manned agricultural aerial spraying, such as heavy workload in route planning, overlaps or omissions in spraying seriously reduce the efficiency of spraying and utilization rate of pesticides. This paper presents the design and development of a navigation system for manned agricultural aerial spraying based on an industrial tablet PC. This system provides three key functions: route planning, spraying navigation and real-time evaluation of spraying quality. The test and application results show that this system has high efficiency in route planning, and the average coverage rate of spraying could reach as high as 96%. Its application effect is remarkable, and as a result, this system can meet the demand of manned agricultural aerial spraying in route planning and navigation.
