  • Page 11: Introduction

    Introduction Description of the SonicResearch™ application SonicResearch™ is a preset for Aixplorer®, under the General application. The Research preset can be used for research protocols only and must not be used to perform clinical diagnosis. The Research preset may be used with the SL18-5, SL15-4, SC6-1, XC6-1, SLV16-5, SL10-2 and SE12-3 probes.

    In practice, if you want to forbid remote access to any of the research data labelled with patient name shall require a de-activation of the ftp feature and perform raw data export through USB. Another solution is to perform research acquisition without logging patient name on the system. Aixplorer® Research Guide...
