Some useful free video editing software

http://www.freemake.com/free_video_converter/ 
This is a very useful free software/ freeware to convert videos from avi, mpg, mpg4 etc. to various formats as well as for converting audio files. A must have. I've used it and there were no bugs detected.


Want to join video clips together in a couple of clicks? Free video joiner is the freeware that does this in a couple of clicks. Easy to use and a very simple interface:

Zweistein is also a simple and free software that is a great video editor.
You can use its crop function to remove those identity details from video clips (remove the names of patients and other such ID details) from the borders of video clips.

Sonography of the fetal ductal arch



   A sagittal section of the fetal ductal arch (see the ultrasound video above) shows the typical hockey stick shape of the ductal arch as it emerges from the fetal right ventricle. Observe closely, that in sagittal section the fetal right ventricle is the chamber that is adjacent to and just behind the anterior chest wall (the sternum) of the fetus.
  The fetal aortic arch, on the contrary is an umbrella shaped structure and is seen to arise more posteriorly (see ultrasound image below).
