SarcOptiM (High Frequency Online Sarcomere Length Measurement)

Introduction

SarcOptiM computes the spatial frequency of the striated pattern of a myocyte. It has been successfully tested on rat ventricular and atrial cardiomyocytes. Although not tested, it is expected to work on skeletal muscle fibers.
The analysis can be performed online on video capture inside ImageJ (e.g.: using the webcam plugin or HF_IDS_Cam plugin) or offline on a previously recorded video.
In the online mode, the HF_IDS_Cam plugin with an IDS UI-1220LE camera allows high frequency online recording of sarcomere shortening (up to 1000 Hz) limited only by the frame rate of the camera.
A complete description can be found in the above publication.
