Comparison of 2D and 3D multichannel audio rendering methods for hearing research applications using technical and perceptual measures

Acta Acustica
Virtual reality with multichannel audio playback is increasingly used in hearing aid research. The purpose of this study is to compare horizontal (2D) and periphonic (3D) rendering methods in terms of localization, minimum audible angle, and perceptual ...

Noise reduction using a Bayesian penalized-likelihood reconstruction algorithm on a time-of-flight PET-CT scanner

EJNMMI Physics, 2019
Purpose Q.Clear is a block sequential regularized expectation maximization (BSREM) penalized-likelihood reconstruction algorithm for PET. It tries to improve image quality by controlling noise amplification during image reconstruction. In this study, the

Intraoperative cerebral perfusion monitoring with ultrafast power doppler imaging

Scientific Reports
Brain perfusion monitoring during cerebrovascular surgery is highly desirable; however, this technology is not yet available to surgeons. Our center has developed and implemented a dedicated ultrafast power Doppler imaging (UPDI) sequence along with a ...

Medical signal processing using the software monitor

, 2016
The study of medical signal processing to monitor the patient with the help of software monitor was discussed. The main advantage of the study is that it offers, in one intelligent monitor, the fusion of multiple sources of information. The application of the Software Monitor were related to high dependency care which give satisfactory care to those ...

Assessing small-lesion detectability and acquisition time optimisation in silicon-detector-Based PET: a phantom study

EJNMMI Physics
Background The adoption of silicon photomultiplier (SiPM) detectors over conventional photomultiplier tubes (PMTs) in Positron Emission Tomography (PET) has enhanced overall system performance.
