• 1 Cycle = 1 peak + 1 trough

• Frequency = # of cycles / sec

• Spatial pulse length (SPL) = # cycles x wavelength

• Penetration = minimum depth at which electronic noise is visible with optimized controls

  • Inversely related to axial resolution

• Axial resolution is affected by SPL

• Lateral resolution is affected by beam width and focal zone

• Manipulation

  • Increase frequency -> decrease wavelength -> decrease SPL = improve axial resolution

  • Increase frequency -> decrease wavelength -> increase attenuation = decrease penetration

  • Decrease beam width = increase lateral resolution
