ABSTRACT
Objective To demonstrate the feasibility and necessity of constructivist pedagogy for teaching biomedical electronics so as to create a new instructional mode. Methods The new mode for teaching biomedical electronics was discussed from two aspects of teaching thought and practice with considerations on constructivist pedagogy connotation as well as the actualities of teaching resources and object. Results Instructional thoughts which boosted students' thinking ability,learning habits and confidence were developed.The instructional practice,which included integrated teaching units, problem-based discussion,task-driven experiment content,was also been achieved.Conclusion The reform of instructional mode gains high practical effect, and provides pedagogical implications to other specialized courses of biomedical engineering.
ABSTRACT
Objective To propose a stream-media technology based on the new transmission technology. Methods Firstly,we explored the advantages and disadvantages of exiting PACS image in LAN (Local Area Network) and WAN (Wide Area Network) and then expounded distance diagnosis related to HIS and PACS,VPN technology,wireless network applications,more points consultation applied technology. At last,we made an analysis of the characteristics of the stream-media transmission technology. Results The characteristics of low bandwidth occupied,high security,and high scalability of stream-media transmission technology fit the needs of PACS development. Conclusion Application of streammedia technology transferred in PACS image provides a new economical and practical technical solution to break through limitation of network bandwidth in medical imaging integrated information,and to thoroughly make use of medical resource.
