“…Additionally, in the very near future ultrasensitive imaging technology will produce extremely low radiation x-rays, which will reduce clinical radiation exposures to approximately 400 times lower than the already very low level that current technology allows. 110 When that technology is clinically available the exposure levels will be so low that the concern over radiation risks will have even less practical relevance.…”

The concern over x-ray exposure risks can overshadow the potential benefit of radiography, especially in cases where manual therapy is employed. Spinal malalignment cannot be accurately visualized without imaging. Manual therapy and the load tolerances of injured spinal tissues raise different criteria for the use of x-rays for spinal disorders than in medical practice. Current regulatory bodies rely on radiography risk assessments based on Linear-No-Threshold (LNT) risk models. There is a need to consider radiography guidelines for chiropractic which are different from those for medical practice. Radiography practice guidelines are summaries dominated by frequentist interpretations in the analysis of data from studies. In contrast, clinicians often employ a pseudo-Bayesian form of reasoning during the clinical decision-making process. The overrepresentation of frequentist perspectives in evidence-based practice guidelines alter decision-making away from practical assessment of a patient’s needs, toward an overly cautious standard applied to patients without regard to their risk/benefit likelihoods relating to radiography. Guidelines for radiography in chiropractic to fully assess the condition of the spine and spinal alignment prior to manual therapy, especially with high velocity, low amplitude spinal manipulation (HVLA-SM), should necessarily differ from those used in medical practice.

“…[14] Moreover, some of the traditional scintillators, such as agglomerated powders and bulk crystals, need to be sintered at high temperatures, and their luminescence is difficult to adjust in the visible region due to afterglow effects. [15,16] In recent years, the metal halide perovskites have emerged as promising materials for wavelength-selective PDs due to their excellent optoelectronic properties, including strong light absorption, low defect states density, decent carrier mobility, continuously tunable bandgap, and so on. [5,[17][18][19][20] Lin et al first reported the filterless narrowband PDs by employing solutionprocessable mixed lead halide perovskites.…”

Spectral sensing plays a crucial part in imaging technologies, optical communication, and other fields. However, complicated optical elements, such as prisms, interferometric filters, and diffraction grating, are required for commercial multispectral detectors, which hampers their advance toward miniaturization and integration. In recent years, metal halide perovskites have been emerging for optical-component-free wavelength-selective photodetectors (PDs) because of their continuously tunable bandgap, fascinating optoelectronic properties, and simple preparation processes. In this review, recent advances in wavelength-selective perovskite PDs, including narrowband PDs, dual-band PDs, multispectral-recognizable PDs, and X-ray PDs, are highlighted, with an emphasis on device structure designs, working mechanisms, and optoelectronic performances. Meanwhile, the applications of wavelength-selective PDs in image sensing for single-/dual-color imaging, full-color imaging, and X-ray imaging are introduced. Finally, the remaining challenges and perspectives in this emerging field are presented.
