DESIGN AND IMPLEMENTATION OF A COMPUTERIZED ULTRASOUND IMAGING INFORMATION SYSTEM

ABSTRACT
Computerized ultrasound imaging information system is used in the processing of ultrasound information and report. Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy, young adults and thus, 20 kHz serves as a useful lower limit in describing ultrasound. The production of ultrasound is used in many different fields, typically to penetrate a medium and measure the reflection signature or supply focused energy. The reflection signature can reveal details about the inner structure of the medium. The most well known application of this technique is its use in sonography to produce pictures of fetuses in the human womb. There are a vast number of other applications as well. The upper frequency limit in humans (approximately 20 kHz) is caused by the middle ear, which acts as a low-pass filter. Ultrasonic hearing can occur if ultrasound is fed directly into the skull bone and reaches the cochlea without passing through the middle ear. Carefully-designed scientific studies have been performed supporting what the authors call the hypersonic effect - that even without consciously hearing it, high-frequency sound can have a measurable effect on the mind This program is implemented using visual basic program and MS Access.
