MACHINE LEARNING IN ULTRASOUND IMAGING

BME/MEDPHYS 578

Covers the physics associated with magnetic resonance imaging and diagnostic ultrasound emphasizing techniques employed in medical diagnostic imaging. Major MRI topics include: physics of MR, pulse sequences, hardware, imaging techniques, artifacts, and spectroscopic localization. Ultrasound based topics covered include: propagation of ultrasonic waves in biological tissues, principles of ultrasonic measuring and imaging instrumentation, design and use of currently available tools for performance evaluation of diagnostic instrumentation, and biological effects of ultrasound. Gain an understanding of the technical and scientific details of modern non-ionizing medical magnetic resonance and ultrasound devices and their use in diagnosing disease.

SURGSCI 750

Introduction to hands-on ultrasound imaging and expand on selected portions of ultrasound physics, literature and problem-based case studies.

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/MEDPHYS 575

Propagation of ultrasonic waves in biological tissues; principles of ultrasonic measuring and imaging instrumentation; design and use of currently available tools for performance evaluation of diagnostic instrumentation; biological effects of ultrasound.

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.
