Radiation characteristics of an antenna should be tested through a precise measurement procedure. To provide an actual parameter of an antenna radiation, measurement must be performed in the far-field region and its distance is proportional to the antenna's dimension. Therefore, in a limited space of an anechoic chamber facility, antenna measurement has a constraint to a maximum dimension of the antenna...
Transesophageal Echocardiography (TEE) is used to visualize ultrasound heart images for diagnosis or surgery monitoring. The existing TEE is operator dependent and does not provide sufficient safety features to localize the TEE probe tip inside the human body. In order to improve safety in the usage of TEE, a novel technique for TEE probe tip localization has been developed. This technique is based...
In recent decades, the use of three-dimensional ultrasound (3DUS) imaging of organs has been growing rapidly compared to its two-dimensional ultrasound (2DUS) type. The use of freehand technique in 3DUS system may help to improve the natural flexibility performance. To realize a 3DUS freehand imaging, a position tracking system which measures the US probe position in real time is added. The design,...
There exists growing demand for the improvement of Transesophageal Echocardiography probe control. In order to provide remote control, a Fuzzy Logic based approach is presented. Preliminary results based on MATLAB2014a enclose the simulation of desired motor behavior of 2 Dynamixel MX-28 which actuate ultrasound probe movements. We conclude that the Fuzzy Logic toolbox is highly applicable for simulating...
The quality of ultrasound images highly depends on sonographer skills. This paper describes a platform for the reduction of operator dependency during transabdominal ultrasound examinations. The design includes a linear system to enable automatic transabdominal ultrasonography of the cervix. The system was integrated within APLIO MX SSA-780A TOSHIBA ultrasound machine. Results show operator independent...
