SPED 54 Presentation SPED 54 Presentation Presentation Transcript

  • A Primer of Diagnostic Ultrasonic Imaging
  • A Primer of Diagnostic Ultrasonic Imaging Brought to you by Nicole and her dad
  • A Primer of Diagnostic Ultrasonic Imaging Brought to you by Nicole and her dad with special acknowledgment to our expert sonographer Denise Nunes
  • A Primer of Diagnostic Ultrasonic ImagingOutline of Topics Covered  What is ultrasonic imaging, what can be imaged and why?  Modalities • A-mode, B-mode, 2D imaging • 3D rendering • M-mode • Doppler modes * Color Flow (CF) * Spectral Doppler
  • A Primer of Diagnostic Ultrasonic Imaging What is ultrasonic imaging? .
  • A Primer of Diagnostic Ultrasonic Imaging What is ultrasonic imaging? Ultrasonic imaging is the transmission of very high frequent inaudible sound waves into the body by an ultrasonic transducer, then receiving echo information for tissue structures with the same transducer. The echo information is then electronically processed to form a viewable image of the tissue structures. This is very similar to to the sonar process used in the Navy for finding underwater objects.
  • A Primer of Diagnostic Ultrasonic Imaging What can be imaged? Soft tissue and fluids.
  • A Primer of Diagnostic Ultrasonic Imaging What can be imaged? Soft tissue and fluids . What can’t be imaged? Bone and air, e.g. lungs
  • A Primer of Diagnostic Ultrasonic Imaging Why?
  • A Primer of Diagnostic Ultrasonic Imaging Why? Diagnostic ultrasonic imaging is used by doctors to view internal body structures for the diagnosis of diseases, abnormality of structures, and even blood flow.
