All rights reserved.—Apart from its usefulness in interventional procedure, ultrasound-guided needle insertion has also crucial problem in terms of needle visibility. The inconsistency of needle visibility is needed to be quantified to evaluate the significance of possible technical factors, e.g., imaging strategies, needle type, and needle-transducer relative position. Needle visibility quantification is important as an initial step before further investigation about fundamental physics behind it and further development of needle visibility enhancement. 20G, 150 mm spinal needle inserted in degassed water phantom is imaged with B-mode Flex Focus 800 BK-Medical using 12 MHz linear transducer and 6 MHz curved transducer. The insertion angles are varied between 15°-70°. The quantified visibility representing each needle position are combined into a comprehensive visibility map covering the whole insertion area. It is also evaluated based on insertion length. The results suggest that both linear and curved transducer, for all insertion angles, the distributions of needle visibility have similar pattern and they are not affected by the insertion length. Practically, this applied method of visibility quantification can be used as specific reference and to predict the distribution of needle visibility limited by the specification of needle and ultrasound system, i.e., range of transducer’s frequency and needle’s size.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Needle visibility,Ultrasound,Visibility quantification,—interventional procedure[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work was supported by Indonesia Endowment Fund for Education (LPDP) and the Ministry of Research, Technology and Higher Education of Republic of Indonesia (competency-based research funding).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.46300/91011.2020.14.3[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
