developing an algorithm based on an inertia sensor, consisting of a 3 axis-accelerometer, a 3-axis gyroscope_x000D_
and a 3-axis magnetometer, which is embedded inside the ultrasound probe to estimate the trajectory of_x000D_
ultrasound scan, b) integrating the trajectory information with 2D ultrasound scanned images to reconstruct 3D_x000D_
images and c) establishing the accuracy of the 3D reconstructed images. The developed algorithm will provide_x000D_
scientific underpinning for Clarius' promotion of their ultrasound system for 3D images reconstruction. The_x000D_
current ultrasound system from Clarius is a handheld device which uses Wi-Fi Direct and Bluetooth to connect_x000D_
to an iOS or Android smart device to display 2D images. The data from the accelerometer, gyroscope and_x000D_
magnetometer are sent to the smart device at 60 Hz with 14-bit resolution. Clarius has not yet implemented the_x000D_
inertia sensor data to provide position and orientation information. Integration of the gyroscope measurements_x000D_
plus the magnetometer data should accurately estimate the orientation. The calculated orientation will be_x000D_
combined with the accelerometer data which subtracts the earth's gravity information and perform a double_x000D_
integration to estimate the position. However, since the inertial measurements are usually noisy and biased, the_x000D_
integration steps from angular velocity to rotation and from acceleration to position will introduce integration_x000D_
drift. To minimize the integration drift, a periodic reset or capturing data in a short period of time may resolve_x000D_
the drifting problem., program purpose french : The objectives of this project are to develop and validate tools to use ultrasound for medical imaging by a)_x000D_
