Book 1989latest major breakthroughs in the history of diagnostic ultrasound. Although early attempts at inserting ultrasound transducers in natural cavities of the body can be traced back more than two decades, only in the past few years has technology allowed the development and commercialization of effecti

Further, since the attenuation . of the beam is related to its frequency . as . = ...... = attenuation coefficient at 1 MHz; . ≈ 1), the transcutaneous visualization of deep structures requires the use of low frequencies, which limits image resolution and, consequently, the diagnostic capabilities.

Thus, adequate diagnostic studies are not always obtained. Various techniques have been developed in an attempt to overcome these limitations.

With the ultrasound transducer in direct contact with the intraperioneal organs, sound wave propagation is optimal and high frequencies can be used, yielding better image quality and more information than in transcutaneous sonography.
