Area of Science:

  • Medical imaging
  • Diagnostic ultrasound

Background:

  • Three-dimensional ultrasonography (3D US) is established in obstetrics but not yet standardized for soft tissue and joint diagnostics.
  • Current limitations include handling difficulties and lack of standardized acquisition or visualization protocols.

Purpose of the Study:

  • To evaluate the feasibility and potential of 3D US in soft tissue and joint diagnostics.
  • To identify challenges and future directions for 3D US in this field.

Main Methods:

  • Utilized 3D arrays and image correlation techniques for volumetric data acquisition.
  • Employed planar and spatial visualization modes (transparency, surface) for data interpretation.

Main Results:

  • 3D sonography demonstrated higher accuracy, validity, and reproducibility in soft tissue and joint investigations compared to conventional methods.
  • Visualization challenges were noted due to low acoustic impedance differences, requiring time-consuming postprocessing for surface mode.

Conclusions:

  • Despite current limitations, 3D US shows significant potential for enhanced soft tissue and joint diagnostics.
  • Future advancements in real-time acquisition, geometric precision, and automated segmentation are expected to improve usability and expand applications.
