Biopsies play a crucial role in diagnosis of various diseases including cancers. In this study, we developed an augmented reality (AR) system to improve biopsy procedures and increase targeting accuracy. Our AR-guided biopsy system uses a high-speed motion tracking technology and an AR headset to display a holographic representation of the organ, lesions, and other structures of interest superimposed on real physical objects. The first application of our AR system is prostate biopsy. By incorporating preoperative scans, such as computed tomography (CT) or magnetic resonance imaging (MRI), into real-time ultrasound-guided procedures, this innovative AR-guided system enables clinicians to see the lesion as well as the organs in real time. With the enhanced visualization of the prostate, lesion, and surrounding organs, surgeons can perform prostate biopsies with an increased accuracy. Our AR-guided biopsy system yielded an average targeting accuracy of 2.94 ± 1.04 mm and can be applied for real-time guidance of prostate biopsy as well as other biopsy procedures.
活检在包括癌症在内的各种疾病的诊断中起着至关重要的作用。在本研究中，我们开发了一种增强现实（AR）系统，以改进活检程序并提高靶向准确性。我们的AR引导活检系统使用高速运动跟踪技术和AR头戴设备，以显示叠加在真实物理对象上的感兴趣器官、病变及其他结构的全息表示。我们AR系统的首个应用是前列腺活检。通过将术前扫描（如计算机断层扫描（CT）或磁共振成像（MRI））纳入实时超声引导程序，这种创新的AR引导系统使临床医生能够实时看到病变以及器官。随着前列腺、病变及周围器官可视化的增强，外科医生能够更准确地进行前列腺活检。我们的AR引导活检系统平均靶向准确率为2.94±1.04毫米，可应用于前列腺活检以及其他活检程序的实时引导。
