Maybe you didn't read my other http://news.bbc.co.uk/1/hi/sci/tech/4357613.stm" [Broken] wherein it's claimed that they've already accomplished it.vanesch said:Yes, but that's highly hypothetical, no ? We already have to live in 10 dimensions...
Sure... fine. But, wouldn't it have been a lot cheaper to just tell these same engineers that we want this or that for other applications? Why not just put them to work building better medical imagers, rather than having to develop the technology secondhand?The scaling up in itself needs a lot of R&D. You don't see this as spectacular breakthroughs, it are many many small improvements in the reliability of the production process and so on which make up the bulk of this research.
For instance, at PSI I remember having heard a talk about research on back-to-back connections between arrays of photodiodes on silicon and the ASIC that does the data selectioning and compression before sending it on an optical fibre. The industrially available techniques didn't have a high enough density of connection points to do this. So a lot of research was done to improve this, and the density was increased 16 fold.
Now that these back-to-back connections are available, the whole sandwich of photodiodes + electronics is used for high resolution medical X-ray imaging. It took 6-7 years of a 10 person R&D group to devellop this.
There are many such examples.
