Improved free and open source blood vessel diameter tracking software

VasoTracker pressure myography (diameter tracking) software

VasoTracker pressure myography software v1.1.0

Our diameter tracking software  allows you to monitor pressure myography experiments. It’s entirely free.

Updated features

We added a whole load of new settings to let you customize the diameter tracking performance (without learning Python). With VasoTracker you can measure blood vessel diameter across the whole field of view or within a region of interest. We made a few other tweaks and also fixed some bugs, this included fixing a memory bug that caused VasoTracker to rash intermittently on long recordings. Default speed is 4 Hz.

Need to relax in the lab?

VasoTracker is famous for reducing myograph-related stress. But, we thought we could help a little more. That’s why you can now relax with some Space Invaders.

VasoTracker 1.1.0

Requires Microsoft Windows 10 Pro 64-bit & 8GB of RAM.  μManager and camera drivers may have other requirements.

MAKE SURE YOU INSTALL THE PREREQUISITES (SEE HERE)

VasoTracker Offline Analyzer diameter tracking update

Artery diameter tracking software

VasoTracker Offline Analyzer v1.1.0

We have released a few versions of our offline blood vessel diameter tracking software, but this one is definitely the best. It features the algorithm we used in this paper.

Diameter tracking features

We have added a whole load of new settings so that you can customize the diameter tracking algorithm (without learning Python). VasoTrackerOA measures diameter across the whole field of view, within a region of interest, or across a single scan line (drawn in any direction). We even removed a few buttons that didn’t work properly. Download it and give it a try on your myography or ultrasound data!

Stress management features

Some users reported that our diameter tracking software was very helpful in reducing workloads and stress levels. We realize that those who haven’t yet downloaded VasoTrackerOA may have large amounts of data to be analyzed. Such large backlogs of data are associated with increased stress and reduced productivity. Recognizing this, and taking inspiration from scientific reports such as this one, we incorporated a new feature to boost productivity and help ones mental health  flourish. Space Invaders.

So if you are a bit stressed out, or just have some blood vessel imaging data that you would like to analyze, get our latest version.

VasoTracker Offline Analyzer 1.0.1: offline diameter tracking software

We’ve just released our software for offline analysis of blood vessel images. The offline analyzer can create diameter recordings from a variety of imaging data. It works with pressure myography video files, fluorsence imaging recordings (en face arteries), and even ultrasound imaging.

We are quite proud of this package, as it speeds up our analysis significantly and allowed us to easily analyze old data. If you want to measure blood vessel diameter in video recordings, download our open source (free!) software a try. Get it here.

VasoTracker Offline Analyzer 1.0.1 (27/04/2019)

Requires Microsoft Windows 10 Pro 64-bit & 8GB of RAM.

Features:

      • Measure blood vessel diameter from a variety of imaging data (myography, fluorescence imaging, ultrasound).
      • .tiff and .avi file compatibility
      • Many adjustable settings!

Pressure myography on an open source, 3D-printed microscope using Raspbery PI

 

The Pachter lab has shared their designs for the Poseidon project created at the California Institute of Technology. Poseidon is a 3D-printed  syringe pump and microscope system designed for microfluidic experiments, and it is described in a preprint published on bioRxiv. The complete system is controlled by a tiny Raspberry Pi computer and comes with a 7" touchscreen interface!We've been adapting the Poseidon microscope design for use with our pressure myographs. We've even rewritten our diameter tracking software to run with on the Raspberry Pi.

Pressure myographs require some way to image the blood vessel mounted in the chamber. We’ve been recommending cheap upright AmScope microscopes that you can get on Amazon, or Nikon’s cheapest inverted offerings. But we thought it would be nice if VasoTracker had its own open source microscope. So we’ve been adapting the Poseidon microscope design for use with our pressure myographs. We’ve even rewritten our diameter tracking software to run on the Raspberry Pi.

All in, the microscope costs less than £150 to make! Check back here soon for an update!

COMING SOON! Analyze blood vessel images with our open source analyzer

If you have some blood vessel imaging data, you might be in need of some analysis software. With our Offline Analyzer, you can extract diameter measurements from a wide range of blood vessel images is easy. There are options to analyze pressure myography, fluorescence, and even ultrasound data!

Have other imaging data that you want to analyze? We want our software to be as useful as possible, so get in touch and let us know!

 

 

 

 

VasoTracker is alive
