Purpose: To assess the comparability of linear measurements of dental implant sites recorded from multidetector computed tomography (MDCT) images obtained using standard dose filtered backprojection (FBP) technique with those from various ultralow doses combined with FBP, adaptive statistical iterative reconstruction (ASIR) and model based iterative reconstruction ( MBIR) techniques. The results of the study may contribute to MDCT dose optimization for dental implant site imaging.

This study demonstrates the formation of extremely smooth and uniform
formamidinium lead bromide (CH(NH 2 ) 2 PbBr 3 = FAPbBr 3 ) fi lms using
an optimum mixture of dimethyl sulfoxide and N , N -dimethylformamide
solvents. Surface morphology and phase purity of the FAPbBr 3 fi lms are
thoroughly examined by fi eld emission scanning electron microscopy and
powder X-ray diffraction, respectively. To unravel the photophysical properties
of these fi lms, systematic investigation based on time-integrated and timedependent
