A gesture-controlled projection display for CT-guided interventions

Purpose The interaction with interventional imaging systems within a sterile environment is a challenging task for physicians. Direct physician-machine interaction during an intervention is rather limited because of sterility and workspace restrictions. Methods We present a gesture-controlled projection display that enables a direct and natural physicianmachine interaction during computed tomography (CT)-based interventions. Therefore, a graphical user interface is projected on a radiation shield located in front of the physician. Hand gestures in front of this display are captured and classified using a Leap Motion Controller (LMC). We propose a gesture set to control basic functions of intervention software such as gestures for 2D image exploration, 3D object manipulation and selection. Our methods were evaluated in a clinically oriented user study with 12 participants. Results The results of the performed user study confirm that the display and the underlying interaction concept ar...
