Three-dimensional (3D) ultrasound overcomes limitations of conventional 2D imaging by enabling better visualization of 3D anatomy. This advanced ultrasound technology improves diagnostic accuracy and facilitates precise volume measurements.

Area of Science:

  • Medical Imaging
  • Diagnostic Ultrasound
  • Biomedical Engineering

Background:

  • Conventional ultrasound provides 2D images of 3D anatomy, requiring mental integration by diagnosticians.
  • This 2D approach presents challenges in localization and reproducibility for follow-up studies.
  • Advances in 3D ultrasound have emerged to address these inherent limitations.

Purpose of the Study:

  • To review the advancements in 3D ultrasound imaging systems and techniques.
  • To explain how 3D ultrasound overcomes the limitations of 2D imaging for anatomical assessment.
  • To detail methods for 3D image reconstruction, viewing, and volumetric measurement.

Main Methods:

  • Description of 3D ultrasound system developments, including mechanical, free-hand, and 2D array scanning.
