AnSo is designed by anesthesiologists for anaesthesiologists.
AnSo is for more than just regional anaesthesia. It includes other perioperative uses of ultrasound such as:
Nerves, Vascular Access, Airways, Transthoracic Echo and Lumbar Spine.

AnSo contains:
- over 300 images and over 1500 colour overlays,
- Sonoanatomy clearly displayed,
- Probe Positions,
- Landmarks Sketches,
- Loops.

Carry this resource in your pocket to help identify anatomical structures with ultrasound. AnSo allows the user to identify sonoanatomy by placing single or multiple colour overlays on and off the ultrasound images. Landmarks commonly used for pattern recognition of major structures are simplified using chalkboard sketches. Short loops demonstrate some dynamic anatomical features and surface anatomy images localise probe positioning.
AnSo does not require an internet connection to run. Once downloaded all data is stored on your device so it will work anywhere. It can be useful both in and out of theatre, when performing procedures, and when learning or teaching ultrasound.
The app has been designed to be easily updated with new images as perioperative ultrasound use expands, and new understanding of the sonoanatomy develops.

Download AnSo today and always have easy access to sonoanatomy answers.

One of the best ultrasound apps available. Does what it says efficiently, and better than any other app available. Highly recommended as a compliment to other regional apps.

Great ap for clinical and exam revision

Clear, concise and comprehensive reference which is rapidly accessible

Great teaching tool

This app will be great to teach US anatomy at the bedside. Will also be a welcome aid memoir for the embarrassing moments where you just can't remember the name of things. A must for all teachers and trainees.
