Ultrasonography

7.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Summary

Determining virtual source (VS) locations for diverging-wave ultrafast ultrasound imaging is complex. A new constant radial distance (r) method offers comparable image quality to the constant opening angle (β) method, simplifying VS placement.

Area of Science:

  • Medical Imaging
  • Ultrasound Technology
  • Acoustic Wave Propagation

Background:

  • Ultrasound array probes utilize virtual source (VS) locations for diverging wavefronts to achieve ultrafast compounded images with a broad field-of-view.
  • Optimizing VS placement is challenging due to the infinite possibilities within the half-plane.

Purpose of the Study:

  • To propose and evaluate a simplified method for virtual source (VS) placement in diverging-wave ultrafast ultrasound imaging.
  • To compare the performance of a constant radial distance (r) VS placement method against a constant opening angle (β) method.

Main Methods:

  • Simulations using Field II with a 64-element, 2.7 MHz phased-array geometry to analyze point-spread functions (PSFs).
  • Experimental imaging of a tissue-mimicking phantom using a research scanner and corresponding probe.
  • Evaluation metrics included lateral and axial resolution, peak side-to-main lobe amplitude ratio (PSMR), maximum amplitude, and generalized contrast-to-noise ratio (gCNR).

Main Results:

  • Both constant-r and constant-β methods demonstrated consistent PSF lateral resolution increase with range (≈38 µm/mm) and similar mean axial resolution.
  • Mean differences in PSMR and amplitude between the two methods were less than 5% and 4%, respectively.
  • The constant-β method yielded the highest generalized contrast-to-noise ratio (gCNR), with differences between methods within ±1%.

Conclusions:

  • A streamlined constant-r method for VS placement achieves comparable image quality to the constant-β method in diverging-wave ultrafast imaging.
  • The constant-r method simplifies the process of determining practical VS locations for broad field-of-view ultrasound imaging.
