Rick,
Medical grade monitors are specially tuned to render the greyscale values of an image better, have higher contrast ratios, better refresh rates, and better backlighting for even illumination. It all adds up to a better looking xray image. However, the price tag is significantly higher than standard consumer grade displays. The pixel resolution of a display, just like the pixel resolution of a sensor, is not the sole determinant of image quality.

What does medical grade monitor mean? Is that different that the 1080 by 920 or whatever?

Well explained Ekram
Also. Add that a medical grade monitor shows a higher quality resolution than the standard monitor in our office.

Ray,
There have been numerous independent studies done with all factors fixed, other than the xray head. Every one of those demonstrated a clear correlation between the type of head, the age of that head, and the range of adjustments possible, with the image quality generated by the SAME sensor used with the various xray heads.
It is obvious that new or better sensors will generate better quality images than the previous generation of sensors. What is your new sensor? Dexis went from Classic to Platinum, Schick went from the Elite to the 33 and those upgrades have made a significant difference in the native image quality generated by those sensors. It is also a fact that software rendering algorithms now play a bigger role in image quality than it previously did. I have seen images taken from the SAME sensor in different software and found clearly discernible differences.
The conclusions are: xray heads affect image quality, sensor design affect image quality, and software rendering affects image quality. All equally weighted.

Not necessarily, Ekram.
I hate a bad sensor (posted about it). and I took my GOOD sensor back and forth from office to office. I have four year old mounted Gendex xray sources, I have a Nomad, two Belmonts, and two old SS White units (one that went bad we are fixing). ALL radiographs taken with ALL of the systems were VERY similar..differences were undetectable.
I WILL say this.. The NEW sensor we have is a HUGE improvement over the old one.
Radiation is radiation. KVP, MW, time..are the differences.

It is a fact that the type of xray head, the health of the components (power supply, tube, etc.) all factor into image quality. So, if anyone is concerned about improving diagnostic quality of the images, then all xray sources are not equal.

After using the Nomad for a couple of years, it opens up some new thinking, but it is hard to know if it make fiscal sense. But if you want a different image, one that would be impossible or difficult with a fixed head, well, you just do it, quick and easy. No biggie. The problem is that all of these things just open up new ways of thinking, and can challenge the business models we have so carefully crafted!

Yea a used one is around $2k. It's like a used car. If the head works (which is easier to find companies that rebuild them!), it's either spend $700 on a control board, $2k for a use refurbished one, or $5k on a new one. All things considered, I think my decision to buy just the control is a sound one..for now!
We'll see after the month warranty runs out!

Ray,
Another option is to buy a used unit that came in on a repo or lease. Several companies sell them and they have been tested with limited warranties.

An interesting thing came up yesterday when we were trying to find a new control box / timer board for my old SS White Marksman I.
It took several calls to many distributors all over the U.S. to finally find one.
During my search, I had to secure a dental supply company guy repair man who I trust. One guy I asked a pretty interesting question about.
My question was this..
Would my practice be worth the extra several thousand dollars I'd be putting into a brand new xray source versus getting all the ones there, all in working order?
He nicely said to me, 'Ray, your practice would be worth $X..and a new xray in one room would very likely NOT make it worth $X + the cost of a new xray.
Makes sense. SO two of the machines in my Kittanning office are over 30 years old, and so they may break again, but his statement and answer made alot of sense. SO instead of spending $5k on a hand held Nomad or equivalent, I spend $700 on a new control board. An xray source is an xray source. PERIOD. A new one would have the parameters set a bit lower with the digital sensors available, but it's ROI.
