  1. Detective quantum efficiency | Radiology Reference Article ...

    Nov 7, 2024 · Detective quantum efficiency (DQE) is one of the fundamental physical variables related to image quality in radiography and refers to the efficiency of a detector in converting …

  2. DQE measures transfer of signal to noise ratio from the input to the output of a detector. The methodology for measuring DQE in a digital detector has been standardized in IEC 62220-1. …

  3. Detective quantum efficiency - Wikipedia

    The detective quantum efficiency (often abbreviated as DQE) is a measure of the combined effects of the signal (related to image contrast) and noise performance of an imaging system, …

  4. Assessment of Detective Quantum Efficiency: Intercomparison

    Defined as the ratio of the squared image signal-to-noise ratio to the number of incident x-ray photons, the DQE describes how efficiently a system translates incident x-ray photons into …

  5. Image Quality Metrics - Oncology Medical Physics

    Detector Quantum Efficiency (DQE) is a measure of the imaging system’s efficiency in converting data carriers into an image. DQE is influenced by every component of the imaging system and …

  6. Detective quantum efficiency of photon-counting CdTe and Si …

    Results: For detection in a 300-mm-thick object at 120 kVp, the 0.5- and 0.225-mm pixel CdTe systems have 28% to 41% and 5% to 29% higher detective quantum efficiency (DQE), …

  7. Study of DQE dependence with beam quality on GE Essential …

    Detector performance is quantified by means of modulation transfer function (MTF), normalized noise power spectrum (NNPS) and detective quantum efficiency (DQE). We found that …

  8. Quantitative characterization of electron detectors for transmission ...

    Detector performance can be evaluated quantitatively using the detective quantum efficiency (DQE), which measures how much noise a detector adds to a recorded image.

  9. Detective quantum efficiency of electron area detectors in electron ...

    Recent progress in detector design has created the need for a careful side-by-side comparison of the modulation transfer function (MTF) and resolution-dependent detective quantum efficiency …

  10. MTF and DQE enhancement using an apodized‐aperture x‐ray

    Jun 21, 2017 · Acquisition of high-quality x-ray images using low patient exposures requires detectors with high detective quantum efficiency (DQE). We describe a novel apodized …
