An interesting article, and like many things that are read on the internet, only gives the partial story. Sadly, like many of our voters, they don't bother to dig a level or two deeper, instead taking the message at face value and solidifying their belief. And our media system has done a wonderful job at brainwashing most of us.
The root of this 'potential' imaging problem is not the administration, it's not the plans for universal health care, it's not even the manufacturers of the imaging devices!
The problem exists simply with years of compounded greed and corruption, bloating our healthcare system into this gluttonous, inefficient monster.
The USA has the most expensive health care system on planet earth, and ranks DEAD LAST in quality of care against every other developed country - even some south american countries offer better quality of care for a tiny fraction of the price. Yet the media loves to spout stories of how these other countries have horrendous waiting lines and terrible care. I've lived in Europe and Australia, using public healthcare systems that frankly put even the most expensive US medical establishments to shame - I worked for the world's leading software company and had the best healthcare insurance in the country, didn't pay a dime for anything. Don't believe the propaganda:

To further elaborate before I conclude on the imaging question. Consider something as simple a procedure as an appendectomy, it can cost from the cost of a fridge to the cost of a house. Same procedure, but can differ by tens/hundreds of thousands. Average cost is $33,000.00 in the USA - average people without adequate insurance would lose everything for one of the most basic and routine surgeries! Their house - GONE. Their kids chance of attending college - GONE. They could spend their lives digging themselves out of debt, most likely going bankrupt. Or they could hop over to Canada (say you are on vacation) without insurance and have it done for less than $2000.00 by the best of surgeons - madness!

In conclusion, this article on imaging is just another example of why we NEED HEALTHCARE REFORM, we need the government to step in and offer healthcare options that are affordable and available for everyone, and over time will inevitably cause the intrinsic greed of the healthcare/insurance establishment to HAVE TO CUT THE FAT and be COMPETITIVE. Imaging is not the problem, it's the greed and corruption in the middle that drives the cost up to astronomical levels.
Another recent example specifically on imaging, shows that you can have an MRI in France for $280, but in the US you will pay upwards of $1080 (I've seen charges on my insurance bill far higher, again supporting the great variance in pricing across the USA).

The original poster of this article is simply worried about his job,and I understand where he is coming from. Given the crazy costs for almost every single medical procedure in this country, public (Obama-Care) healthcare options may initially be unable to offer higher cost things such as imaging scans. But, the scans shouldn't cost so much, and that's really the root problem. Until insurance companies and the medical establishment are slowly forced to be competitive and stop their insane greed, it's true that some people may not have access to imaging.
But let's be truly real here. If you already have good health insurance, you don't have to worry - imaging is covered. If you don't have health insurance, you may not be able to get necessary imaging, but this is not because of Obama-care or health reform. Please understand that it's the very same companies/establishments that paid governor Romney millions of dollars to try and win this election that are stopping you from gaining access to these scans. They want to continue charging 10 to 100 times more for procedures than every other developed country where people have easy, available and affordable access to the necessary care to keep them healthy, in some cases alive. These companies/establishments don't want to change, they like their multi-billion dollar profits and who can blame them? It's been a great ride - let's not worry about that 47% of Americans as governor Romney put it. Let them suffer, who cares.
But this can't continue, if only for the sake of creating a system where ANY sick person can receive help, and not literally lose the shirt off his/her back in the process.
Healthcare reform is an absolute necessity in this country and the only people against it are those who currently profit from it's current state - those in the insurance/medical/pharmaceutical establishments, and those who don't want to pay any more taxes to help support the very people who made them wealthy in the first place.
I'll leave you with a thought from the wonderful philanthropist Bill Gates. He realized that his amazing wealth as the world's wealthiest, flowed from the people of the world, without them buying his products, he would have nothing. So it's only right that some of that money should flow back to help the world that provided it. IN fact, he is flowing back over $40 billion dollars of his own money, almost his entire fortune.

So, is the real problem Obama-Care?

I've got an idea! Have the government stop borrowing money from a privately and foreign owned bank, called the "Federal" Reserve, which is causing the inflation on any meaningful service or commodity.
Then bring the jobs back that bring tax revenue, and insured patients.
This is systemic, deeper than just healthcare.

Also I would think that a big problem is that insurance companies can pay half the price if you have insurance. Example. CXR: A given person's insurance company has a negotiated payment of $90. Another person who doesn't have an insurance company that negotiated that price has to pay $210 for the same service. This is totally bogus. The cost should remain static from person to person. Same with bank loans. Interest should remain static. If the bank feels the risk is too large, simply don't give the loan. The loanee will be much better off without paying a 600$/month bill on something someone who makes decent money would pay 400$/month. Charging interest rates that you know they can't afford will not make them more apt to pay up and does NOT reduce the risk taken in giving the loan. Just makes the honest poor people pay the way for the dishonest ones. When it all boils down the bottom line is, stealing should be illegal.

And, starting in 2013, Medical device manufacturers will have to pay a 2.3% tax on sales of equipment. That cost will get passed directly on to the end user. Brilliant!

Also, currently, Section 179 of the Internal Revenue Code allows taxpayers to deduct up to $139,000 of depreciation on qualifying new and used assets placed into service during the 2011 tax year. Starting in 2013, the current legislation has reduced the deduction to $25,000. Seems to me our government doesn't want the sales of equipment in the Health Care Market. Equipment sales will no doubt really drop off starting in 2012 and more layoffs will happen in the Health Care Equipment industry.

I work for a healthcare system, and almost everything I've experienced has been because of Liability. If tort reform were invoked, I would expect to see healthcare costs drop.

All you have to do is sit in front of a tv, and every other commercial is for a law firm trying to attract customers who MAY have had, or MAY know, someone who was affected by this or that.

I haven't heard of any part of Obamacare that deals with this. Probably because it's all about turning healthcare over to the government - which is inefficient and unable to balance a budget in it's own right.
