Modulation Transfer Function (MTF)
DRIQ allows quick and easy MTF calculation from edge images
Normalised Noise Power Spectrum (NNPS)
Quickly assess the distribution of noise power as a function of spatial frequency
Noise Equivalent Quanta (NEQ)
Automatic interpolation of the NNPS and MTF to produce the NEQ.
Detective Quantum Efficiency (DQE)
Simply choose your beam quality to obtain the DQE from the NEQ
JL DICOM Browser
Easily search, identify and filter your DICOM and NEMA images in preparation for assessment
Convert pixel values to air kerma for linear, logarithmic, and power law systems
IEC standard methods incorporated
Options are available to force compatible routines (MTF, NNPS, NEQ, DQE, JL DICOM Browser) to follow the IEC standard methodology
DICOM stack averager
Average a stack of DICOM images whilst retaining the DICOM header from the first image in the stack.
Perform a basic uniformity check using five automatically positioned regions of interest
Assess the uniformity of a digital image and highlight problem areas
Variance and artefact images
Generate variance and artefact images with a single click
Advanced Java users can programatically access the routines in their own software.
