ARDMS SPI Exam Questions & Answers 2024 Complete

Spatial Pulse Length is directly proportional to - ️️the Number of Cycles in the Pulse and the Wavelength (Directly Proportional means that increased SPL will increase both the number of cycles in the pulse and the wavelength if increased). Spatial pulse length is inversely proportional to - ️️Frequency (MHz) (Inversely Proportional means that increased SPL will lower frequency. This is because axial resolution is better with lower frequency) In soft tissue, if the frequency of ...
