"GE’s Vscan is a handheld, pocket-sized visualization tool that allows for non-invasive ultrasounds."
I can only imagine the military-grade ultrasound cannon required for an invasive ultrasound exam.
No cannons ( they didn't say invasion ultrasound...) but :
Transesophageal echocardiograpy (heart) : http://pie.med.utoronto.ca/TEE/TEE_content/TEE_standardViews_intro.html
Endobronchial ultrasound (lung and mediastinum) : http://www.medscape.com/viewarticle/455720_7
Endoscopic ultrasound (pancreas liver etc) : http://www.asge.org/patients/patients.aspx?id=380
Intravascular ultrasound (coronoary arteries etc) : https://en.wikipedia.org/wiki/Intravascular_ultrasound
Transrectal ultrasound(guess) : http://emedicine.medscape.com/article/457757-overview
As mentioned by others trans vaginal is pretty common.
Most of these are usefull technologies but not the priority for resource constrained environments. The device featured in the TFA is intriguing. The question is how flexible a crystal they'll put in it, eg how specialized a device will it be will it see only very shallow structures only deep? Can they make a device at this cost with a useful resolution? The answer is probably yes but it will be interesting to see.
