BME 8730 - Diagnostic Ultrasound Imaging

Underlying principles of array based ultrasound imaging. Physics and modeling techniques used in ultrasound transducers. Brief review of ID circuit transducer models. Use of Finite Element techniques in transducer design. Design considerations for 1.5D and 2D arrays will be reviewed. Diffraction and beamforming will be introduced starting from Huygen’s principle. FIELD propagation model will form an important part of the class. In depth discussion of various beamforming and imaging issues such as sidelobes, apodization, grating lobes, resolution, contrast, etc. The course addresses attenuation, time-gain-compensation and refraction. Finally, speckle statistics and K-Space techniques will be introduced. Laboratories will involve measuring ultrasound image metrics, examining the effect of various beamforming parameters and simulating these on a computer using Matlab. Prerequisite: instructor permission, BIOM 6310 and BIOM 6311. Preparation: Undergraduate Physics, Electronic circuit analysis, Differential Equations, Fourier and Laplace Transforms, Sampling Theorems.
