混合现实全息影像在心血管教学中的应用价值

The application of mixed reality holographic image in cardiovascular imaging training

目的评价混合现实全息影像在心血管影像诊断培训中的应用价值。方法选取解放军总医院放射科新入科进修的未接触过心血管影像工作的进修医生30名,采用随机数字表法平均分成两组,A组(n=15名),B组(n=15名),分别进行传统教学方法及混合现实全息影像结合传统教学方法进行心血管影像培训。通过考试及教学满意度调查比较两组在教学效果方面的差别。结果传统教学组和混合现实全息影像结合传统教学方法组的考试成绩分别是(67.7±3.0)分和(74.9±4.0)分,差异有统计学意义。教学满意度分别为60.0%和86.7%(P>0.05)。结论混合现实全息影像结合传统教学方法在心血管影像诊断教学中优于传统的教学方法。

Objective To evaluate the application value of mixed reality holographic image in cardiovascular imaging training.Methods A total of 30 doctors without cardiovascular imaging experience,who worked in PLA general hospital for further educa tion of radiology,were enrolled and divided into A(n=15)and B(n=15)groups randomly.The Group A was given traditional teaching method.The Group B was given mixed reality holographic image combined with traditional teaching method in cardiovascu lar training.The teaching effects of the two groups were compared by the test result and teaching satisfactory survey.Results The score of traditional teaching and mixed reality holographic computer combined with traditional teaching were respectively(67.7±3.0)and(74.9±4.0),with statistically significant difference.Teaching satisfaction were respectively 60.0%and 86.7%(P>0.05).Conclusion Our study suggests that mixed reality holographic computer image with traditional teaching is superior to traditional teaching in cardiovascular imaging training.
