  • 本研究旨在以電腦3D多媒體功能與網際網路的特性,建構一個醫學的輔助教學系統;系統模擬從病患進入醫院,先要接受醫師問診,如果推斷所患的是某些與遺傳相關的疾病,可能必須先詢問家族病史等相關資訊;接著醫師們可以根據病例診斷流程樹狀圖(Medical Decision Making Tree)一步步診斷出病人的目前病況為何。

    然而病患可能因為病況緊急而住進醫院,接下來便可以進行虛擬病患(Virtual Patient)的模擬機制,另一方面,在住院接受治療的過程中,病患可能因為某種病況需要送進手術房進行開刀手術,因此本研究也提出了Cut Server 以及挖洞功能,提供醫師們模擬手術房處理病患的動作。

    最後嘗試將所發展之系統應用在醫學以外的領域,例如工廠職業訓練中,訓練使用者模擬工廠的突發事件。

    This thesis report a multimedia interactive learning system which combines both characteristics of 3D multimedia and the internet for a simulation learning system.
    First we establish a simulated hospital and the user can play as a doctor’s role in it to diagnose a virtual patient. In the system, the user may ask the patient some questions about their medical history, present illness, and so on, and perform some examinations. They can make a diagnosis and give treatments based on a medical decision making tree. The users can use some tools to draw the patient’s pedigree.
    The system also simulate the situation of a virtual patient in the emergency room. The system also provides a tool for the user to cut through a human body model to learn some anatomical knowledge when it is needed.
    We demonstrate how to apply our system in some fields other than medical science. For example, the employees can learn how to handle the incidents in a factory in our simulation system.
