Sonography Principles and Instrumentation
Content Outline
(Spring 2009)
Updates to the following sections of the SPI Content Outline have been made: Sections I., V., & VI.
The topics being covered on the ARDMS examinations will not change with the release of the SPI in Spring 2009. ARDMS’ volunteer subject-matter experts reviewed the current content of the specialty and physics examinations to determine which topics could be moved to the SPI examination and which needed to be covered at the specialty level. A small amount of specialty-specific physics content will be shifted from the UPI, CPI, and VPI physics examinations to the appropriate specialty examination, e.g., FE, PE, AE, or VT. These changes are minor and will not affect the examinations’ overall structure.
