Comparison of photoacoustic image reconstruction algorithms using the channelized Hotelling observer.
We demonstrate the use of task-based image-quality metrics to compare various photoacoustic image-reconstruction algorithms, including a method based on the pseudoinverse of the system matrix, simple backprojection, filtered backprojection, and a method based on the Fourier transform. We use a three-dimensional forward model with a linear transducer array to simulate a photoacoustic imaging sys...
متن کاملChannelized Hotelling Observer Performance for Penalized-Likelihood Image Reconstruction
What type of regularization method is optimal for penalized-likelihood image reconstruction when the imaging task is signal detection based on a channelized Hotelling (CHO) observer? To answer such questions, one would like to have a simple analytical expression (even if approximate) for the performance (SNR) of the CHO observer given different reconstruction methods. Bonetto, Qi, and Leahy (IE...
متن کاملOptimization of Medical Imaging Display Systems Using the Channelized Hotelling Observer
Medical-imaging systems are designed to aid medical specialists in a specific task. In order to satisfy the quality preferences of a human observer, the optimization of medicalimaging systems has to include measurements of human performance and has to use these results for final tuning of the physical parameters of the system. To measure human performance it is necessary to conduct the psychoph...
متن کاملImplementation of a channelized Hotelling observer model to assess image quality of x-ray angiography systems.
Evaluation of flat-panel angiography equipment through conventional image quality metrics is limited by the scope of standard spatial-domain image quality metric(s), such as contrast-to-noise ratio and spatial resolution, or by restricted access to appropriate data to calculate Fourier domain measurements, such as modulation transfer function, noise power spectrum, and detective quantum efficie...
