About

Sonolex

Features
Read full description

Sonolex is the structured echo case logbook built for cardiology training programs. Echo cardiology requires logging hundreds of cases during training. Sonolex replaces handwritten logs and spreadsheets with a fast, clinically organized workflow. LOG CASES IN SECONDS Enter echo findings using natural shorthand — the same notation you already use. Type "ef 55 mild mr tr mild rvsp 40 ivc flat" and Sonolex instantly parses it into a structured report: LVEF, valve findings, PASP, and IVC collapsibility — organized by system. BUILT-IN CLINICAL CHECKS Sonolex applies ASE-guideline logic to grade diastolic dysfunction and generate heuristic impressions. Labels are always marked as heuristic — never overstated as AI. SUPERVISOR REVIEW WORKFLOW Send any case for digital co-sign. Your supervisor reviews findings on the web or iOS and signs off — building an auditable record for your training portfolio. NBE-READY EXPORT Export your complete case log as a CSV compatible with NBE requirements. One tap, no reformatting. PRIVATE AND OFFLINE-FIRST Cases are stored on your device. Nothing leaves your phone without your explicit action. Requires iOS 17 or later.
