With tissue harmonic imaging, what is one advantage mentioned?

Tissue harmonic imaging is a notable technique in ultrasound that utilizes the nonlinear propagation of sound waves as they travel through the body tissues. One prominent advantage of this method is the decreased artifact in the near field. In conventional ultrasound imaging, artifacts, such as reverberation and side lobes, can obscure the true nature of the structures in the near field, which is the area closest to the transducer. However, with tissue harmonic imaging, the harmonic frequencies produced during echogenic interactions tend to reduce these artifacts significantly, leading to clearer images and better visualization of tissues near the transducer.

This improved image clarity is critical for diagnostic accuracy and enhanced assessment of anatomical structures in the near field. As a result of this reduction in near field artifacts, clinicians can rely more on the quality of the images produced, leading to more accurate diagnoses.
