Abstract

Purpose: To update normative data on fluoroscopy dose indices in the United States for the first time since the RAD-IR study in the late 1990s.Materials and Methods: The DIR-Fluoro pilot collected data from March 2018 through December 2019, with 50 fluoroscopes from 10 sites submitting data. Primary radiation dose indices including fluoroscopy time (FT), cumulative air kerma (Ka,r), and kerma area product (PKA) were collected for interventional radiology fluoroscopically-guided interventional (FGI) procedures. Clinical facility procedure names were mapped to the ACR Common procedure lexicon. Distribution parameters including the 10th, 25th, 50th, 75th, 95th, and 99th percentiles were computed.Results: Dose indices were collected for 70,377 FGI, with 50,501 ultimately eligible for analysis. Distribution parameters are reported for 100 ACR Common IDs. FT in minutes, Ka,r in mGy, and PKA in Gy-cm2 are reported here as (N; median [interquartile range]) for select ACR Common IDs: IVC filter insertion (1726; FT: 2.9 [1.8-4.3]; Ka,r: 55.8 [27.7-117.6]; PKA: 14.19 [7.17-31.67]); IVC filter removal (464; FT: 5.7 [3.3-12.6]; Ka,r: 178.6 [72.2-430.3]; PKA: 34.73 [13.74-85.81]); nephrostomy placement (2037; FT: 4.1 [2.0-8.6]; Ka,r: 39.2 [13.4-122.7]; PKA: 6.61 [2.24-23.65]); percutaneous biliary drainage (952; FT: 12.4 [4.8-24.5]; Ka,r: 160.5 [43.2-446.8]; PKA: 21.32 [6.79-65.95]); gastrostomy placement (1643; FT: 3.2 [2.0-5.0]; Ka,r: 29.1 [13.2-67.1]; PKA: 7.29 [2.97-18.01]); TIPS placement (327; FT: 34.8 [23.2-53.3]; Ka,r: 813.0 [355.5-1490.8]; PKA: 181.47 [87.71-407.49]).Conclusions: The ACR DIR-Fluoro pilot has provided state of the practice statistics for radiation dose indices from IR FGI procedures. These data can be used to prioritize procedures for radiation optimization, as demonstrated in this work. [ABSTRACT FROM AUTHOR]

19. Neutron Inelastic Scattering Cross Sections From 159Tb(n, nʹϒ)

Author

Seo, Pil-Neyo, Egan, James J., Kegel, Gunter H. R., Desimone, David J., Ko, Young J., Kim, Don-Soo, and Ji, Chuncheng

Abstract

Scattering cross sections for fast neutrons were investigated for low-lying levels of 159Tb by a Ge detector with a NaI(Tl) Compton suppression annulus in conjunction with the pulsed-beam time-of-flight technique. Thirty-eight transitions from 27 levels were observed and differential gamma-ray production cross sections for the 159Tb(n, n, nʹϒ) reaction were measured at 125° for incident neutron energies from 400 to 1000 keV. Level cross sections were also inferred. Neutron scattering cross sections for the states at 241, 348, 363.5, 535 and 580.7 keV are compared to the ENDF/B-VI, JEF-2, and JENDL-3 evaluations.

Abstract

The Quality assurance of ultrasound clinical imaging systems is essential for maintaining their performance to the highest level and for complying with the requirements by various regulatory and accrediting agencies. Although there is no standardization yet, most of the quality assessment procedures available in literature are proposed for B‐mode and Doppler imaging. However, ultrasound imaging systems offer a variety of advanced imaging modes, besides B‐mode and Doppler, which are primarily aimed at improving image quality. This study presents computer‐based methods for evaluating image quality for the advanced imaging modes of ultrasound imaging systems: harmonic imaging, spatial compounding imaging, adaptive speckle reduction, and tissue aberration correction. The functions and parameters proposed for evaluating image quality are: grayscale mapping function, image contrast, contrast‐to‐noise ratio (CNR), and high‐contrast spatial resolution. We present our computer‐based methods for evaluating image quality of these modes with a number of probe and scanner combinations, which were employed to image targets in ultrasound phantoms. The functions and parameters here proposed in image quality performance evaluation are: grayscale mapping function, image contrast, CNR, and high‐contrast spatial resolution. We show that these quantities could be useful in developing standardized methods for evaluating the advanced ultrasound imaging modes, especially when the advanced mode resulted in subtle visual differences.
