【摘要】：目的探索新的立体医学影像教学方案,实现3D立体视觉教学,降低学习影像解剖难度,提高学习效率。方法 CT、MRI、SPECT及PET等检查用GE公司AW工作站获得三维重建影像,X线检查应用立体摄影摆位床获得3D影像,将获得的影像用于编写《医学影像三维立体解剖图谱》,配送自主研发的立体观片镜,以便在普通的书籍上实现3D立体视觉影像。实验分a、b两组(每组100名学生),两组同学均对头部、颈部、胸部、腹部和盆部等5个部位的相同解剖影像进行自学,a组先用立体镜观看3D立体影像自学15min,再观看2D影像自学15min,b组同学先观看2D影像自学15min,再用立体镜观看3D影像自学15min,最后采用调查问卷的形式对比两种方法的教学效果。结果认为3D影像在主观影像清晰度上优于2D影像的同学a组占98%,b组占97%;认为3D影像在辨识解剖结构难度小于2D影像的同学a组占98%,b组占96%;认为更喜欢观看3D影像的同学a组占98%,b组占96%。各组统计学结果 P0.01。结论通过立体影像学习,同学们在影像清晰度、降低学习难度和喜欢观看的影像方面均认为3D立体影像比2D影像更有优势,该结果不受观看2D和3D影像顺序的主观影响。立体影像为探索医学影像教学方法提供了新思路,有助于医学影像教学的发展。
[Abstract]:Objective to explore a new teaching scheme of stereoscopic medical image, to realize 3D stereoscopic vision teaching, to reduce the difficulty of studying image anatomy and to improve learning efficiency. Methods CT,MRI,SPECT and PET were used to obtain 3D reconstructed images by AW workstation of GE Company, and 3D images were obtained by stereoscopic imaging in X-ray examination. The obtained images were used to compile three-dimensional anatomical atlas of medical images. Distribution of self-developed stereoscopic mirror in order to achieve 3 D stereo vision image on ordinary books. The experiment was divided into two groups (100 students in each group). The same anatomical images of head, neck, chest, abdomen and pelvis were self-taught in both groups. The students in group B watched 2D images for 15 mins, then stereoscopic images for 15 mins. Finally, questionnaire was used to compare the teaching effects of the two methods. The results showed that 3D images were superior to 2D images in the definition of 3D images in group A, group A accounted for 97%, group A considered that 3D images had less difficulty in identifying anatomical structure than 2D images, group a accounted for 96% of students with difficulty in identifying anatomical structure. Students who thought they preferred to watch 3D images accounted for 98% in group a and 96% in group B. The statistical results of each group were P 0.01. Conclusion through stereoscopic image learning, students think that 3D stereoscopic image is superior to 2D image in terms of image definition, learning difficulty and viewing image, and this result is not affected by the order of viewing 2D and 3D images. Stereoscopic image provides a new way to explore the teaching method of medical image and is helpful to the development of medical image teaching.
