Virtual environments have brought the use of realistic training closer to many different fields of education. In medical education, several visualization methods for studying inside the human body have been introduced as a way to verify the structure of internal organs. However, these methods are insufficient for realistic training simulators because they do not provide photorealistic scenes or offer an intuitive perception to the user. In addition, they are used in limited environments within a classroom setting.
We have developed a virtual dissection exploration system that provides realistic three-dimensional images and a virtual endoscopic experience. This system enables the user to manipulate a virtual camera through a human organ, using gesture-sensing technology. We can make a virtual dissection image of the human body using a virtual dissection simulator and then navigate inside an organ using a virtual endoscope. To improve the navigation performance during virtual endoscopy, our system warns the user about any potential collisions that may occur against the organ's wall by taking the virtual control sphere at the virtual camera position into consideration.
Experimental results show that our system efficiently provides high-quality anatomical visualization. We can simulate anatomic training using virtual dissection and endoscopic images.
Our training simulator would be helpful in training medical students because it provides an immersive environment.
虚拟环境使逼真的培训更接近许多不同领域的教育。在医学教育中，已经引入了几种用于研究人体内部的可视化方法，作为验证内部器官结构的一种方式。然而，这些方法对于逼真的训练模拟器来说是不够的，因为它们不能提供逼真的场景，也不能给用户提供直观的感知。此外，它们仅在教室环境中有限的环境中使用。
我们开发了一种虚拟解剖探索系统，提供逼真的三维图像和虚拟内窥镜体验。该系统使用户能够通过手势感应技术操作穿过人体器官的虚拟相机。我们可以使用虚拟解剖模拟器制作人体的虚拟解剖图像，然后使用虚拟内窥镜在器官内部导航。为了提高虚拟内窥镜检查过程中的导航性能，我们的系统通过考虑虚拟摄像机位置处的虚拟控制球体，警告用户可能与器官壁发生的任何潜在碰撞。
实验结果表明，我们的系统能够有效地提供高质量的解剖可视化。我们可以使用虚拟解剖和内窥镜图像进行解剖学训练模拟。
我们的培训模拟器将有助于医学生的培训，因为它提供了身临其境的环境。
