Curriculum
Every domain covered, start to finish.

A few example topics from each domain — not the full lesson list.

Foundations of Ultrasound Physics
e.g. what is sound, acoustic parameters, key relationships
Describing Sound Waves
e.g. frequency, wavelength, propagation speed, amplitude
Pulsed Sound
e.g. pulse duration, PRP & PRF, duty factor
How Sound Interacts With Media
e.g. reflection, attenuation, acoustic impedance
Transducers
e.g. how transducers work, matching layer, frequency
Sound Beams
e.g. beam anatomy, focal depth, divergence
Display Modes
e.g. A-mode, B-mode, M-mode
Two-Dimensional Imaging
e.g. array types, image formation
Resolutions
e.g. axial, lateral, slice thickness, temporal
Pulsed Echo Instrumentation & Image Processing
e.g. receiver function, image formation, processing tools
Harmonics & Contrast Agents
e.g. harmonic imaging, contrast enhancement
Hemodynamics
e.g. flow patterns, stenosis, venous flow
Doppler Physics & Optimization
e.g. Doppler effect, aliasing, color & power Doppler
Artifacts
e.g. shadowing, reverberation, mirror image, side lobes
Bioeffects, QA & Professional Responsibility
e.g. safety, quality assurance, sonographer responsibility

Still deciding?
Let your timeline choose for you.
Core

A budget-friendly way to start. No SPI date yet — you just want physics to finally make sense.

Premium

You learn best by testing yourself, and want to know you actually understand it before test day.

Pro

Your SPI is coming up — the full runway, plus how to break questions down, recognize patterns, and review fast when it counts.
