BACKGROUND/AIM: Augmented reality (AR) is a new technology that provides new awareness by using a computer to extend the real environment perceived by humans. Optical see-through head-mounted displays (OST-HMD) are worn on the head and can faithfully generate an AR image by wearing the device on the head as a spectacle-type device. We developed an ultrasound-guided needle biopsy technique using OST-HMD for breast tumors.
PATIENTS AND METHODS
Moverio BT-35E (Seiko Epson Corp, Nagano, Japan) was used as the OST-HMD device. This technique involves performing needle biopsy under direct vision via the gap at the bottom of the display while the ultrasound images are projected on the display of the OST-HMD worn on the head.
RESULTS
With this technique, needle biopsy can be executed smoothly with no posture restrictions. A flip shade affixed to the OST-HMD has 2% transmittance, which enables clearer projection of the images.
CONCLUSION
This article outlines the ultrasound-guided needle biopsy using OST-HMD. We established a safe and accurate biopsy technique with technological innovations using AR.
背景/目的：增强现实（AR）是一种新技术，通过计算机使用户对真实环境的感知得到增强。光学穿透式头戴式显示器（OST-HMD）戴在头上，可以通过将设备作为眼镜式设备戴在头上来忠实地生成 AR 图像。我们开发了一种使用 OST-HMD 进行乳腺肿瘤超声引导下针活检的技术。
患者和方法
使用 Moverio BT-35E（精工爱普生株式会社，长野县，日本）作为 OST-HMD 设备。该技术涉及在佩戴在头部的 OST-HMD 的显示器上投影超声图像的同时，通过显示器底部的间隙进行直视下的针活检。
结果
使用该技术，无需限制姿势即可顺利进行针活检。贴在 OST-HMD 上的翻转遮阳板具有 2%的透光率，可更清晰地投影图像。
结论
本文概述了使用 OST-HMD 进行超声引导下的针活检。我们利用 AR 的技术创新，建立了一种安全、准确的活检技术。
