Abstract&Several collections of content representing the human anatomical structure have been introduced. However, most of these contain analog content, such as illustrations, which have difficulty in realistically displaying human organs because they use artificial color and simplified drawings. Digital forms of a human anatomy atlas can provide realistic images from arbitrary viewpoints with real colors. We propose a multiple-volume rendering method for a stereoscopic immersive dissection simulator. It provides a stereoscopic display incorporating a motion recognition sensor, such as the Microsoft Kinect. Users can operate this system without touching or manipulating conventional input devices. To verify the effectiveness of our system, we developed a medical application called virtual dissection. Experimental results show that our system efficiently provides highquality immersive medical data visualization. Keywords Virtual dissection · Gesture recognition · Volume rendering · Visible korean

Introduction
Visualization methods for human anatomy are widely used in medical imaging [1, 2]. Accurate diagnosis is possible when we use a reconstructed 3D image rather than a 2D image acquired from computed tomography (CT) or magnetic resonance imaging (MRI), because a 3D image provides more accurate spatial information. Recently, several immersive systems have been proposed to help a user experience simulation of the real world. Some of them have sensors for measuring the distance between the user and the camera to recognize user operation. The Wii K. Kwon · D.-S. Kang · B.-S.

(Nintendo), Playstation Move (SONY), Kinect (Microsoft) and Leap Motion (Leap Motion) are typical examples. These motion recognition devices can increase immersion of user interaction, and they have become compact in size. However, they are dependent on a predefined operating environment, because these sensors cannot accurately identify and interpret all user gestures. As computer technology advances, a variety of medical devices are being invented and huge volumes of medical data are produced from those devices. The Visible Human, the Chinese Visible Human and the Visible Korean are wellknown examples, which enable us to observe the internal structure of the human body with non-invasive methods [3-7]. Since a series of these images is regarded as 3D texture sampled at very high resolution, the size is in the hundreds of gigabytes, even when we scan only a very small region of the human body. These images help to improve the accuracy of a virtual diagnosis. In this paper, we provide an immersive dissection experience system using multiple-volume visualiza
