Functions for CMR feature tracking strain analysis

Introduction

This R package implements different methods for analyzing CMR feature-tracking derived data from the strain module of the software Segment (v2.0, Medviso®, Lund, Sweden)

DISCLAIMER: This package has no official association with Medviso®

Currently implemented methods

• Septal-to-Lateral wall Delay (SLD)
  • perc: strainpeak criteria as percent of maximum strain (SLD_perc)
  • point: strainpeak criteria with threshold and increase in percentage point strain (SLD_point)
• Earliest-to-Latest Segment Delay (ELSD)
  • perc: strainpeak criteria as percent of maximum strain (ELSD_perc)
  • point: strainpeak criteria with threshold and increase in percentage point strain (ELSD_point)
• Circumferential Uniformity Ratio Estimate (CURE)
• Circumferential Uniformity Ratio Estimate by Singular Value Decomposition (CURE_SVD)
