Dose Reduction in Dental CT: A Phantom Study With Special Focus on Tin
The determined dose-length products of the nine examinations were 5.0–111.9 mGy · cm with a calculated effective whole body dose of 20.7–505.9 μSv. Cone-beam CT was in the upper midfield with an effective dose of 229.3 μSv. ... Tin filter protocols (protocols 1–3) showed lower cortical attenuation (difference, ≈ 300 HU) than …

The effect of tin prefiltration on extremity cone-beam CT
Introduction: While tin prefiltration is established in various CT applications, its value in extremity cone-beam CT relative to optimized spectra has not been thoroughly assessed thus far. This study aims to investigate the effect of tin filters in extremity cone-beam CT with a twin-robotic X-ray system. Methods: Wrist, elbow and ankle joints of two cadaveric …

Radiation dose ranged from 17.4 mGy in the clinical standard protocol without tin filter to as low as 0.7 mGy with tin prefiltration. Image quality ratings and CNR for tin-filtered scans with 100 kV were lower than for 80 kV studies with copper prefiltration despite higher dose (11.2 and 5.6 vs. 4.5 mGy; p < 0.001).

Band pass filter plan in fluoroscopy for high energy range
Abstract. In fluoroscopy, the absorption edge, the energy range, and the X-ray spectrum peak are the most important factors in filtration to obtain a proper image. Here, an experimental study was conducted to determine the filters that remove low-energy spectrums and attenuate high-energy ranges so that they cannot fundamentally affect …
