We developed a touchless display system that allows the user to control the medical imaging software via hand gestures in the air. We conducted this study to verify the effectiveness of this novel touchless display system as a tool for assisting with surgical imaging.
The patient's computed tomography (CT) data are generally observed on a display during surgery. The "Dr. aeroTAP" touchless display system was developed to generate virtual mouse events based on the position of one hand. We conducted comparative analyses of using the Dr. aeroTAP vs. using a regular mouse (control group) by measuring the time to select a 3D image from 24 thumbnail images on a screen (study 1) and to then see the CT image on the DICOM viewer (study 2).
We used the Dr. aeroTAP in 31 hepato-biliary operative procedures performed at our hospital. In study 1, which measured the time required to select one of 24 thumbnails, there were significant differences between the mouse and Dr. aeroTAP groups for all five surgeons who participated (P < 0.001). In study 2, there were also significant differences in the time required for CT DICOM images to be displayed (P < 0.001).
The touchless interface proved efficient for allowing the observation of surgical images while maintaining a sterile field during surgery.
我们开发了一种非接触式显示系统，允许用户通过空中手势控制医学成像软件。我们进行这项研究以验证这种新型非接触式显示系统作为辅助手术成像工具的有效性。
在手术过程中，通常在显示屏上观察患者的计算机断层扫描（CT）数据。开发了“aeroTAP医生”非接触式显示系统，以根据一只手的位置生成虚拟鼠标事件。我们通过测量从屏幕上的24个缩略图中选择3D图像的时间（研究1）以及随后在DICOM查看器上查看CT图像的时间（研究2），对使用aeroTAP医生与使用普通鼠标（对照组）进行了比较分析。
我们在我院进行的31例肝胆手术中使用了aeroTAP医生。在研究1中，测量了选择24个缩略图之一所需的时间，参与研究的所有五位外科医生的鼠标组和aeroTAP医生组之间存在显著差异（P < 0.001）。在研究2中，显示CT DICOM图像所需的时间也存在显著差异（P < 0.001）。
非接触式界面被证明在手术过程中保持无菌区域的同时观察手术图像是有效的。
