Design and implementation for portable ultrasound-aided breast cancer screening system / 生物医学工程学杂志

Early screening is an important means to reduce breast cancer mortality. In order to solve the problem of low breast cancer screening rates caused by limited medical resources in remote and impoverished areas, this paper designs a breast cancer screening system aided with portable ultrasound Clarius. The system automatically segments the tumor area of the B-ultrasound image on the mobile terminal and uses the ultrasound radio frequency data on the cloud server to automatically classify the benign and malignant tumors. Experimental results in this study show that the accuracy of breast tumor segmentation reaches 98%, and the accuracy of benign and malignant classification reaches 82%, and the system is accurate and reliable. The system is easy to set up and operate, which is convenient for patients in remote and poor areas to carry out early breast cancer screening. It is beneficial to objectively diagnose disease, and it is the first time for the domestic breast cancer auxiliary screening system on the mobile terminal.

Design of Computer-aided System for Adverse Events of Medical Instruments / 医疗卫生装备

Objective To connect with provincial or even national report center for adverse events of medical instruments and set up a computer-aided system for supervision.Methods By designing software,setting up database and online connecting with report center,the computer-aided system for adverse events of medical instruments was utilized to automatic report,early-warning monitoring and report.Key technologies were analyzed.Results Based on computer network,adverse events of medical instruments were automatically reported,collected and managed.Information and consultation could be provided rapidly without error.Conclusion The system not only facilitates management department in medical instruments managing,producing and application,but set a theoretic basis for development and academic teaching of new medical instruments.
