The Guide to SPI

"Mastering Ultrasound Physics"

The Guide to SPI was written to assist sonographers in acquiring proficient knowledge to pass the SPI or physics portion of their credentials exam.

There are over 200 pages and hand-drawn images by a sonographer. A PowerPoint presentation is also available with or without the Review Book to help with visual learners grasp key content and formulas. There is also an extensive test with answers at the end of the book for practice exams.
