Multisim仿真软件在医学影像电子学教学中的应用
|
摘要
目的探讨Multisim仿真软件在医学影像类专业电路实验教学及教学演示中的作用。方法参加研究的对象为大学二年级下学期的医学影像工程专业41名学生,该组学生通过前期学习已具备电路系统、模电/数电和X线机单元电路的理论基础,实验要求学生运用Multisim仿真软件构建X线机单向全波整流电路,并和传统的X线机模拟电路实验箱实验教学进行对比,通过使用满意度调查问卷表分析使用软件仿真方法的教学效果。结果90.2%的学生认为利用Multisim仿真软件构建X线机单元电路教学系统教学效果好于传统的模拟电路实验箱教学方法(X~2=49.98,P<0.01)。教学方法细节评价调查结果表明,82.9%的学生完全同意Multisim仿真软件开发的电路教学系统有利于对不同型号X线球管电气特性的掌握。另外,有87.8%的学生不同意模拟电路实验箱有利于对不同型号X线球管电气特性的掌握。结论 Multisim仿真软件用于医学影像电子学实验教学,有助于培养医学影像专业学生的动手实践和创新能力,提高教学和学习效率。
Objective To explore the role of Multisim simulation software in lab courses of circuits and electronics in medical imaging equipment.Methods Investigation is conducted on a group of 41 sophomore students on the element circuits of X-ray machines.The students were asked to use the Multisim simulation software to develop and test a one-way full-wave rectification circuit,and compare the experimental procedure by using traditional circuit experimental box.The investigation is evaluated via the final satisfaction questionnaire filled by the students.Results 90.2% of the students favored the Multisim simulation software for learning the labs of X-ray machine element circuits over the traditional circuit experimental box teaching method(X~2=49.98,P<0.01).The detail evaluation results show that 82.9% of the students fully agree that the circuit teaching system constructed by Multisim simulation software is useful for learning Xray tubes with different electric characteristics.In addition,87.8% of the students disagree thatthe circuit experiment box can facilitate the learning of different X-ray tubes.Conclusion Multisim simulation software used in the lab teaching of circuits and electronics in medical imaging equipment is helpful to improve the students' ability of hands-on experiences and innovation,as well as strengthen teaching and learning efficiency.
