Bone mineral density radiopaque templates for cone beam computed tomography and multidetector computed tomography [PDF]

open access: yesDigital Diagnostics, 2023
BACKGROUND: Cone beam computed tomography is widely applied for diagnostics and planning various manipulations in the maxillofacial region, for example, dental implantation. Its advantages include high spatial resolution, low radiation exposure, and cost-

Combination of Cross- and Inter-Band Radiometric Calibrations for a Hyperspectral Sensor Using Model-Based Spectral Band Adjustment

open access: yesRemote Sensing, 2020
Recently, the growing number of hyperspectral satellite sensors have increased the demand for a flexible and robust approach to their calibration. This paper proposes an operational method for the simultaneous correction of inter-sensor and inter-band ...

Initial Cross-Calibration of Landsat 8 and Landsat 9 Using the Simultaneous Underfly Event

open access: yesRemote Sensing, 2022
With the launch of Landsat 9 in September 2021, an optimal opportunity for in-flight cross-calibration occurred when Landsat 9 flew underneath Landsat 8 while being moved into its final orbit.

Extended Cross-Calibration Analysis Using Data from the Landsat 8 and 9 Underfly Event

open access: yesRemote Sensing, 2023
The Landsat 8 and 9 Underfly Event occurred in November 2021, during which Landsat 9 flew beneath Landsat 8 in the final stages before settling in its final orbiting path. An analysis was performed on the images taken during this event, which resulted in

INTEGRAL Cross-calibration Status

open access: yes, 2004
The status of the INTEGRAL cross-calibration is presented for a standard X-ray astronomy source, the Crab Nebula, as well as for some weaker sources. The relative flux normalization for the different INTEGRAL instruments is discussed together with spectral shape features.

Radiometer-to-imager in-flight cross calibration and verification

open access: yesOptics Express, 2020
This work develops a method to complete the in-flight cross calibration and verification between a radiometer and an imager hosted on aircraft. The in-flight cross calibration is data transmission through time matching, space matching, and spectral matching of two polarization instruments on the same platform, and this method can not only complete the ...
