The digital interactive textbook for ultrasound physics. 15 modules and 65 lessons you work through rather than read, so you're tapping, guessing and watching things move instead of re-reading paragraphs and hoping it sticks.

Includes the SPI Exam Simulator free: a full length 110 question mock exam, on the clock, with a scaled score and an explanation for every answer choice.

6 months of access, and anything improved along the way lands in your account automatically.
