MEDPHYS 775

Mathematical and physical foundations of the application of acoustics in diagnostic ultrasound. Derivation of wave equations for mechanical waves in fluids and solids from a continuum mechanics perspective. Diffraction theory and methods for acoustic field calculation (analytic, angular spectrum, simulations). Review of interactions of acoustic waves with biological tissue and methods to measure their acoustic properties. In-depth discussion of methods for structural image formation including ray-line scanning, plane wave compounding, synthetic aperture, coded excitation, and spatial coherent imaging. Introduction to novel functional imaging approach, including ultrafast Doppler, molecular ultrasound, functional ultrasound, and super-resolution imaging. Application of the acquired knowledge to perform a systematic literature review of the state-of-the-art of the field for the solution of a relevant clinical problem.

BME/ECE/MEDPHYS 778

Concepts and machine learning techniques for ultrasound beamforming for image formation and reconstruction to image analysis and interpretation will be presented. Key machine learning and deep learning concepts applied to beamforming, compressed sampling, speckle reduction, segmentation, photoacoustics, and elasticity imaging will be evaluated utilizing current peer-reviewed publications.

PHYASST 651

Primary focus is laboratory medicine assessments, heart sounds interpretation, and imaging modalities.

MEDPHYS 666

Introduces concepts and methodology for measuring acoustic properties of materials and for operating and performing physics tests of state of the art clinical ultrasound scanners. Set up and operate a laboratory apparatus employing single element ultrasound transducers. This is followed by hands on experiments that challenge students to explain physical and engineering characteristics of clinical scanners, details of operator controls, features of Doppler and color flow modes, and resolution limitations. Practical scanning exercises provide familiarity with selected applications of clinical ultrasound equipment, both for diagnosis and for guiding interventions. Routine quality assurance tests done by medical physicists are also performed.
