The Design Of Ultrasonic Bladder Volume Scanner Based On FPGA

This study describes the portable three-dimensional ultrasound scan bladder volumemeasurement system design principle and engineering realization. This product, the maindesign the user information preservation, real-time display, and by the end of the printingprocess. In the preservation of capacity, improved the used bladder capacity detector based onultrasound storage quantity too little faults. By increasing the capacity of the flash, and theprocedure of the integration of different level. This product can make the user timely andaccurate information storage and calls, for patients and medical personnel to provide aconvenient. In the algorithm this link, mainly aimed at the men, women to do differentalgorithms, make this product in different classes to get maximum applications. Meanwhile,we analyzed the existing can realize the ultrasound bladder capacity of measurementalgorithm shortcomings, introduced the improved algorithm. The machine use a simpleultrasonic echo of processing circuit, actual test show that, this algorithm and the designmethods of efficient and feasible. In order to realize the stereoscopic imaging,we designed aspecial probe, proposed with two motor in bladder ultrasound detector do180degreesscanning. Every fifteen degrees have a scan, to gain the urinary bladder12different sectionsof ultrasound information, through the method to calculate the volume to the ball.For the algorithm mentioned above and obtaining the stereo image, we use specialbladder mode the ball to do a equipment. Find the capacity and mode of the ball almost thesame capacity, to control error in the less than ten percent, to comply with the nationalstandard of bladder capacity detector based on ultrasound requirements.
