Three dimensional imaging for breast augmentation - A useful tool or just another marketing ploy? Part III
Monday, November 2nd, 2009Part III – A comparison of the available systems – one plastic surgeons personal opinion
There are currently two systems available for computerized imaging and simulation of breast augmentation surgery. Portrait 3D manufactured by AxisThree, a company funded by Siemens and started in 2002. AxisThree claims to use technology developed by Siemens in the Portrait 3D product. Other than the Portrait 3D system, I am unaware of any other products that the company produces. The other system, Vectra 3D, is manufactured by Canfield Scientific, a company specializing in medical imaging with a long history of many successful products including imaging software, which has been in existence about twenty or so years. Canfield is known for its work in standardizing medical photography, so that images can be taken with consistent lighting, positioning and exposure parameters. Their systems are well known to the dermatology pharmaceutical industry, which contracts with them to produce imaging systems for various drug studies. Both systems were released very recently in the past year.
Let’s start with the physical capture device itself. They are pictured below:

The camera system of the Vectra 3D consists of six 12 megapixel cameras arranged into three pods. The pods use mirrors to permit the imaging of subjects from the side without having to have physical extensions to mount the cameras off to the side. The Portrait 3D system has three cameras of 3 megapixels each. The cameras are mounted on extensions out to the side.
The lighting system of the Vectra 3D consists of high powered flash. This permits imaging without the use of additional lighting. The very bright flash emits much more light than the ambient room light, therefore the room light will not affect the exposure and the room lights can be left on during the imaging process. The Portrait 3D uses LED (light emitting diode) technology. On the Portrait 3D, the LED lighting system requires the user to shut off the room lights to prevent interference of the exposure by the room light.
