초록
Water gel pad is excellent in convenience, but it is disposable, so it has the disadvantagethat repeated use is prohibited, and it is economical for students to use disposable water gel padswhen practicing Carotid ultrasonography at university. In this study, a commercially availableagar jelly based on a commercially available disposable gel pad, which is commercially availableat a high price, is produced to search the radio wave medium to produce a pad to remove theechoed image when practicing carotid ultrasound at university. The validity was evaluatedby comparing with carrageenan in the form of one gel pad. When comparing agar jelly andcarrageenan gel pad based on a commercially available ready-made disposable gel pad, agarjelly satisfies all of the quality control compliance criteria, and skin without virtualization dueto reverberation artifacts and comet tail artifacts frequently observed in carotid ultrasound. Itwas found that the structure of the shallow surface close to and was well observed, providing thebest quality images. As a result of these results, commercially available inexpensive agar jelly andcarrageenan gel pads proposed instead of commercial water gel pads are widely used as a veryefficient ultrasonic delivery medium if additional research is expected to establish an accuratebasis as an ultrasonic delivery medium that complements a virtual image.
