"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.

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.
