PHY09 Ultrasound-Computed Tomography (CT)

Ultrasound-Computed Tomography (CT) The experiment clearly shows how an ultrasound CT image is created. The relevance and differences of individual measurement parameters such as attenuation and speed of sound are analyzed and the influence of filters and image processing is investigated. Keywords: reflection, scattering, transmission, absorption, sound attenuation, sound speed, resolution, ultrasound echography (A-image, B-image), tomography, CT image, image processing, filter X-ray CT, MRI and PET are computer-aided imaging procedures that are used in medical diagnostics, industry and research. Processes such as radiation absorption, nuclear magnetic resonance or particle emission are used to generate cross-sectional images using correspondingly measurable physical quantities. Ultrasound computed tomography is another CT procedure. It differs from X-ray CT in that instead of the attenuation of X-rays, the attenuation and the travel times of ultrasound signals in the object being exam
