Direct volume drilling of internal structures using a 2D pointing device
Keiho Imanishi, Megumi Nakao, Kotaro Minato · 2010
Virtual cutting or direct volume drilling systems have possibility of forming practical planning tools in the medical filed. Recently, some techniques [Mads et al. 2009] have been introduced for cutting or drilling through 3D pointing devices such as PHANToM (SensAble Technologies Inc.) for medical training use. However, the interface is not always suitable for clinical use because of the necessity on getting used to 3D operation. Recent studies [Hung-Li et al. 2008] allow the user to drill or to peer isosurface of the volume via 2D mouse interface. However, this approach has a limitation on editing internal or occluded structures that are difficult to be directly observed from outside. This presentation proposes a new mouse-based drilling approach on the volume-rendering image, and newly introduces a framework to interactive drilling on the arbitrary 3D internal region.
