• DRIQ •

Digital Radiographic Image Quality

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, indentify and filter your DICOM and NEMA images in preparation for assessment. No need to sort images first or worry about nested folders or duplicate filenames.

Linearise

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

Other features

DICOM stack averager

Average a stack of DICOM images whilst retaining the DICOM header from the first image in the stack

Quadrant analysis

Perform a basic uniformity check using five automatically positioned regions of interest

Uniformity

Assess the uniformity of a digital image and highlight problem areas

Variance and artifact images

Generate variance and artifact images with a single click
Advanced Java users can programmatically access the routines in their own software
