"While cheaper than CZT detectors, NaI detectors are bulky and produce blurrier images — like taking a photo through a foggy window."
I'm constantly amazed at what these articles do not show. Like if we have an example of a foggy window image and one from CZT and now one from this new sensor, why not show an example of each? A picture is worth a 1,000 words after all, so not including them really does the reader a disservice when reading these articles.
You may not hear, how expensive become now x-ray science, because safety regulations.
At Edison time, technologies was very unregulated, and because of this was cheap and easy achievable, but lot of people harmed, many just die.
Now you cannot just install other detector into existing (commercial) machine, because license for this machine is very strict, and don't accept any changes (or you will lost guarantee).
In developing countries, regulations usually not working so strict, but in developing countries x-ray machines are not so abundant, so they are just busy at working and have no spare time to make pictures for blog.
And if we choose scientific approach (not using commercial machine), to make x-ray machine from scratch, this is just another financial beast, magnitudes bigger.
So, when I see x-ray pictures in some "private" blog, I always wonder, if this is true private, and not another bubble, aimed to engage people and later sell them some other super-duper tech.
From this, it sounds like it hasn't been integrated into an imaging device yet:
"Record energy resolutions are achieved as 2.5% at 141 keV and 1.0% at 662 keV. Single photon imaging with single point and line 99mTc γ-ray sources showcases the high sensitivity of 0.13%~0.21% cps/Bq. Phantom imaging distinctly delineates individual column sources spaced 7 mm apart, indicative of an impressive spatial resolution of 3.2 mm. These findings lay the groundwork for integrating perovskite detectors into nuclear medicine γ-ray imaging systems, offering a balance of cost-effectiveness and superior performance."
