Nettet14. nov. 2012 · Contrary to normal linear regression, where you assume that all the error is the Y variable, in orthogonal regression, you assume there is an error on both variables. This picture from the Wikipedia link above shows the difference: the error is assumed to be orthogonal to the regression line (and not vertical).

Nettet1. sep. 2011 · The uniformity correction table is a uniformity correction method for a particular radionuclide that is acquired for a considerable number of counts (60–120 million) ( 1 – 3 ). This method uses the acquisition computer to evaluate the high-count flood and mean counts per pixel. Nettetlinearity correction: either correct the individual frames directly in the DAS by mea-suring and downloading the appropriate LUTs, or polynomial coeﬃcients, to the DAS; or use a non-linear inversion on the reset-corrected frames as outlined here.

NettetNon-linearity correction improves the accuracy of the spectral shape. Consider electrical dark correction (EDC). Dark current levels tend to vary slightly over time due to temperature variations, and the EDC option will keep the … Linearity correction is based on the Trinamic stepper driver feature that allows defining a custom current-waveform. The default Trinamic waveform is a sine function, but the real waveform can be a little bit different and depends on the stepper motor type. Also, motors of the same type can have different waveforms.
