"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.
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."

Hmm, why do I know this word "perovskite". Wikipedia gives me no clues, just some mineral.
Possible source: Solar panels with this material were hyped a couple years ago.
Ah, that's what it was for me.

IIRC it was some different type of imaging sensor, so looked it up that way
They are used in thin-film solar panel development. Not sure anyone has cracked the big problem with them, which is durability.

Where are the pictures?
