Diagnostic ultrasound: the geophysical way
Kelvin3D is a revolutionary new concept in ultrasound imaging, intended primarily for the medical imaging and diagnostic market. It is protected by patents either granted (US patent) or pending.
It is revolutionary in its approach to three-dimensional ultrasound imaging, because it uses an approach which is diametrically opposed to current ultrasound techniques.
However, it is in fact a very well-tried and tested methodology; - that is, it uses the technique developed over many decades by the oil exploration industry. This is 3-D seismic reflection imaging, scanning into the Earth using low-frequency sound, to search for oil and gas. In effect, the proof of concept for Kelvin3D is there already in the oil exploration industry.
I have developed the US patent, granted in 2004, in collaboration with oral surgeon Mr Duncan Campbell; together we formed a company, Kelvin Biophysics Limited (KBL), to develop the device. KBL was incorporated in 2005 and dissolved in 2010. It was replaced firstly by Kelvinbio Limited and subsequently by Kelvin3D Limited. This last company was dissolved in 2016 but revived in October 2019. As KBL we obtained funding to build and test a prototype Kelvin3D array, and are currently (late 2019) in negotiations with a major medical ultrasound company.
Kelvin3D is not only intrinsically designed for 3-D scanning, but also for four-dimensional imaging. The fourth dimension is time, in addition to the three spatial dimensions of 3-D. What this means simply is a 3-D image which is animated, or turned into a movie. 4-D, which Kelvin3D is capable of, means that we can see an animated 3-D image in real time, without any delay. This will be invaluable in medical intervention, as well as in diagnosis.
