Description
Purpose For clinical routine and clinical trials it is important to provide structured, consistent reports of electrophysiological data. Also, there is the need for further processing of raw data. Moreover, the connectivity to different electrophysiological systems is a major requirement. We will present a system that is capable of reading raw data, evaluate and process it, to present it in a graphical report and to make it available for data management systems or statistical software packages.
Methods The application is based on Java Enterprise Edition. Algorithms can easily be added by dropping a new plug-in into the system. Algorithms like FFT, frequency filters, curve fitting, detrending, intensity-/response-function, a-wave slope detection, and SNR estimation are implemented. The application allows a flexible design of reports based on customizable templates. Templates according for ISCEV standards are included. It also allows exporting data into different formats including Excel or CSV. Currently we are providing an interface for the Espion E2 system, interfaces for LKC UTAS and Roland Consult Reti-port are being developed.
Results The use of open source frameworks allows for easy adaptation of new algorithms for post-processing electrophysiological data, the integration of new standards, outstanding reporting features and interfaces to existing devices or applications.
Conclusion The application is successfully used in routine clinical examinations. Further features are also currently being developed, like the integration of additional electrophysiological systems and the implementation of new algorithms, e. g. wavelet analysis and noise estimation. An auxiliary accomplishment may be the establishment of a DICOM standard.
