The incidence of breast cancer is increasing worldwide, reinforcing the importance of breast screening. Conventional hand-held ultrasound (HHUS) for breast screening is efficient and relatively easy to perform; however, it lacks systematic recording and localization. This study investigated an electromagnetic tracking-based whole-breast ultrasound (WBUS) system to facilitate the use of HHUS for breast screening. One-hundred nine breast masses were collected, and the detection of suspicious breast lesions was compared between the WBUS system, HHUS and a commercial automated breast ultrasound (ABUS) system. The positioning error between WBUS and ABUS (1.39 ± 0.68 cm) was significantly smaller than that between HHUS and ABUS (1.62 ± 0.91 cm, p = 0.014) and HHUS and WBUS (1.63 ± 0.9 cm, p = 0.024). WBUS is a practical clinical tool for breast screening that can be used instead of the often unavailable and costly ABUS.
全球乳腺癌发病率呈上升趋势，这凸显了乳腺筛查的重要性。传统的手持式超声（HHUS）用于乳腺筛查效率高且操作相对简便；然而，它缺乏系统的记录和定位功能。本研究探讨了一种基于电磁跟踪的全乳超声（WBUS）系统，以促进HHUS在乳腺筛查中的应用。收集了109个乳腺肿块，并比较了WBUS系统、HHUS和商用自动乳腺超声（ABUS）系统对可疑乳腺病变的检测情况。WBUS与ABUS之间的定位误差（1.39±0.68厘米）显著小于HHUS与ABUS之间的定位误差（1.62±0.91厘米，p = 0.014）以及HHUS与WBUS之间的定位误差（1.63±0.9厘米，p = 0.024）。WBUS是一种实用的乳腺筛查临床工具，可用于替代通常难以获得且成本高昂的ABUS。
