What is O-Arm, is the X-Ray imaging finally getting a Facelift in tech?

Interesting tech developments seems to be happening in X-Ray imaging, came across news about O-Arm today and also noticed the fluoroscopic ultra-imaging developments and check those below, as well as the link to Hologic?...This area or technology can be quite useful to surgeons and hospitals, this is something they better look at for efficient surgical procedures and precision detection.

Here is the O-Arm, will this help surgeon view different angles, depth and positioning of pedicle screws and so on?.

Have you seen the O-arm™ Imaging System before? We haven’t. Until today, that is. We learned about it this morning when a company’s rep left O-arm™ brochures (and no food) in our physicians’ lounge. The device byBreakaway Imaging, LLC, of Littleton, MA, was FDA-cleared last year and is now distributed by Medtronic.
So here’s the scoop about the device that has a robotics-assisted positioning system:

Also note the following C-Arm Mini, interesting:
