Long-term cross calibration of HJ-1A CCD1 and Terra MODIS reflective solar bands [PDF]
Scientific Reports, 2021 Since its launch on September 6, 2008, HJ-1A has been in the orbit for 13 years. The CCD1 sensor on the HJ-1A has four reflected solar bands. Since the calibration frequency is limited to the annual site calibration, cross-calibration is an effective ...

A European myocardial 123I-mIBG cross-calibration phantom study. [PDF]
J Nucl Cardiol, 2018 Planar myocardial 123I-meta-iodobenzylguanidine (123I-mIBG) scintigraphy is a highly reproducible technique. However, differences in collimator use are one of the most important factors that cause variation among institutions and studies in heart-to-mediastinum (H/M) ratio.
