영문 초록

The examination needle used in ultrasound biopsy is a medical device used to determine whether there is an abnormality in the tissue. Typically, stainless steel is the standard material used for such needles; however, this study wanted to identify a material that could better enhance sound compared to traditional stainless steel. In this study, six types of needle materials available with the biopsy gun were inserted into pork and ultrasound images according to the curved probe and linear probe were evaluated using ultrasound equipment. The findings revealed significant improvements in ultrasound acoustic enhancement with alternative materials compared to stainless steel (p<0.05). The results regarding the depth of each ultrasound image using the curved probe showed that tungsten and brass had high sound enhancement( p<0.05), while with the linear probe, sound enhancement was high in brass, pla, aluminum, and copper( p<0.05). Due to these results, the previously used stainless needle showed lower ultrasound acoustic enhancement than the five types of materials being compared. Consequently, the outcomes of this study provide valuable insights for the development of new needle technologies aimed at minimizing patient risks and improving diagnostic accuracy.
