Sono Savvy - Physics

by Sono Savvy

Sono Savvy – Physics makes ultrasound physics easier to understand, remember, and actually use.Each episode breaks down one Topic at a time, combining core sonography physics concepts with practical explanations, memorable analogies, important formulas and relationships, and real-world scanning applications. The goal is to help diagnostic medical sonography students prepare for class exams and the ARDMS SPI while also understanding how the physics shows up at the machine and affects image quality, Doppler, artifacts, resolution, penetration, and scanning technique.No endless rambling and no memorizing facts without context—just clear, focused explanations designed to help the concepts click.Created for sonography students who want to understand the “why,” not just memorize the answer.

Episodes

  1. 023 Doppler: Turning Motion Into Information

    Break down the Doppler effect, Doppler shift and equation, angle relationships, and the principles behind continuous-wave, pulsed-wave, color, and power Doppler.

  2. 022 Hemodynamics: How Blood Moves

    Learn the physics of blood flow, including laminar and turbulent flow, resistance, pressure, energy, stenosis, Bernoulli’s principle, and the factors that determine how blood moves through vessels.

  3. 021 Contrast Agents: Tiny Bubbles, Big Signals

    Explore how ultrasound contrast agents work, how microbubbles interact with sound, and how contrast-specific imaging techniques use those responses to enhance visualization.

  4. 020 Harmonics: Cleaning Up the Image

    Learn how harmonic frequencies are created, how tissue harmonic imaging works, and how techniques like pulse inversion and power modulation can improve image quality and reduce unwanted artifacts.

  5. 019 Dynamic Range: Controlling Image Contrast

    Understand how dynamic range and compression control the number of gray shades in an ultrasound image, how changing them affects contrast, and when a sonographer would increase or decrease dynamic range clinically.

  6. 018 Resolution: Seeing More Detail

    Break down spatial and contrast resolution, including axial, lateral, and elevational resolution, what controls each one, and how different settings and physics relationships affect the system’s ability to separate structures and subtle differences in tissue.

  7. 017 Image Processing: What the Machine Does With the Data

    Learn how ultrasound systems process and enhance image data, including pre- and post-processing, zoom, interpolation, compounding, frequency-based tools, edge enhancement, elastography, and 3D processing—and what those changes actually do to the image.

  8. 016 Behind the Screen: How the Ultrasound Machine Builds an Image

    Follow the signal through the ultrasound system—from the pulser and beam former to the receiver—and learn how output power, gain, and signal processing shape the image you see on the screen.

  9. 015 Frame Rate Matters: Making Ultrasound Move

    Learn what controls temporal resolution and frame rate, including imaging depth, pulses per image, and the tradeoffs that affect how smoothly motion is displayed in real time.

  10. 014 Slice Thickness & Elevational Resolution

    Understand the third dimension of the ultrasound beam, how slice thickness affects image quality, and how array design, elevational focusing, and related beam behavior influence what appears on the image.

  11. 013 Transducers, Arrays & How the Beam Is Built

    Learn how different transducer designs create, focus, steer, and sequence the ultrasound beam, and how those design choices affect image shape, footprint, and clinical use.

  12. 012 A-Mode, B-Mode, & M-Mode

    Learn the three fundamental ultrasound display modes, how each represents returning echoes, and how amplitude, brightness, and motion are displayed differently.

  13. 011 Resolution: How Ultrasound Separates Detail

    Break down axial and lateral resolution, what determines each one, and why pulse length, beam width, and focusing affect the system’s ability to distinguish structures that are close together.

  14. 010 Sound Beams: Shape, Focus & Divergence

    Learn how ultrasound beams are shaped, where they narrow and widen, what determines focal depth, and how beam diameter changes through the near and far field.

  15. 009 Inside the Transducer

    Explore how ultrasound transducers create and receive sound, including their basic construction, the piezoelectric effect, and the key components that make pulse-echo imaging possible.

  16. 008 The Range Equation: How Ultrasound Knows Where Things Are

    Learn how time-of-flight is used to determine reflector depth and why accurate distance calculations depend on assumptions about how fast sound travels through tissue.

  17. 007 What Happens at a Tissue Boundary

    Explore what happens when sound reaches an interface, including acoustic impedance, reflection, transmission, and refraction—and how those interactions affect echoes, artifacts, and scanning technique.

  18. 006 Attenuation: Why Sound Fades

    Learn how ultrasound loses energy as it travels through tissue, how decibels and attenuation coefficient describe that loss, and why frequency and distance matter for penetration and image quality.

  19. 005 Intensity: Where, When & How Much

    This episode covers how ultrasound intensity is measured and reported, including spatial and temporal intensity concepts, how they’re combined, and the key rules for comparing different intensity measurements.

  20. 004 Pulsed Ultrasound: Timing Is Everything

    This episode covers pulse duration, spatial pulse length, pulse repetition period and frequency, and duty factor—what each one means, how they relate, and how pulsed ultrasound timing works.

  21. 003 Describing Sound: The 7 Key Parameters

    This episode breaks down the seven parameters used to describe sound waves: period, frequency, amplitude, power, intensity, wavelength, and propagation speed, including how they relate to one another and what determines each one.

  22. 002 How Sound Waves Work

    This episode explains the basics of sound including how sound waves move, the difference between transverse and longitudinal waves, acoustic variables, and how waves interact through constructive and destructive interference.

  23. 001 Physics Foundations: Relationships, Units & Conversions

    Build the foundation for ultrasound physics graphs, direct and inverse relationships, reciprocals, units, metric prefixes, powers of ten, and unit conversions—the basic tools you’ll use throughout the rest of physics.
