Efficient anomaly detection from medical signals and images
International Journal of Speech Technology, 2019Anomaly detection is a very vital area in medical signal and image processing due to its importance in automatic diagnosis. This paper presents three efficient anomaly detection approaches for applications related to Electroencephalogram (EEG) signal processing and retinal image processing.

Effect of noise correlation on detectability of disk signals in medical imaging
Journal of the Optical Society of America A, 1985Pixel signal-to-noise ratio is one accepted measure of image quality for predicting observer performance in medical imaging. We have found, however, that images with equal pixel signal-to-noise ratio (SNRp) but different correlation properties give quite different observer-performance measures for a simple detection experiment. The SNR at the output of

Biometrical Journal, 2000
Summary: We study the performance of a screening procedure R of Chen, Melvin, and Wicks (1999) when it is adopted prior to the signal detection procedure Rkkr proposed independently by Kelly (1986) and Khatri and Rao (1987). Through simulation results, we show that the probability of detection for \(R_{kkr}\) is significantly improved when procedure R ...

Programable Bandwidth Bio-medical Amplifier for Multiple Bio-potential Signals Detection Systems
2021 IEEE International Midwest Symposium on Circuits and Systems (MWSCAS), 2021This work presents a tunable bandwidth bio-medical amplifier controlled by controlling the gain bandwidth of highly linear rail-to-rail operational amplifier. The proposed bio-medical amplifier capable to accommodate frequencies starts from 50 Hz up to 10 kHz to detect multiple bio-potential signals: EEG, ECG, EMG, PCG and Aps, using fixed and small ...

A Novel Millimeter Wave Radar Sensor for Medical Signal Detection
2018 IEEE International Microwave Biomedical Conference (IMBioC), 2018Short-range non-contact sensors are able to detect the precise movements of subjects and to estimate the distance from the sensor to the subject. These radar sensors are employed in new fields, far from their primary usage, which was restricted to security and military applications.

Multiresolution for the detection of xiphoidal sounds in noisy medical audio signals
Proceedings EC-VIP-MC 2003. 4th EURASIP Conference focused on Video/Image Processing and Multimedia Communications (IEEE Cat. No.03EX667), 2004In this paper a method we have developed in order to detect particular events (xiphoidal sounds) in swallowing audio signals is presented. The difficulty of the problem comes from the noisy nature of our medical audio signals, due to biological and environmental reasons.

A Drill Signal Detection Technology for Handheld Medical Drilling Device
2014 International Symposium on Computer, Consumer and Control, 2014This research aims to create a medical drilling device where surgeons can receive the signal and data on the computer screen. We analyze the current signal extract from hall effect-based linear current sensor using a Raspberry Pi engineer board to detect the breakthrough signal.

Perception and Detection of Signals in Medical Images
1992We are interested in how well the human visual system performs signal detection, discrimination, identification and recognition tasks given noise-limited medical images. This paper will discuss the use of statistical decision theory concepts to understand both fundamental and human limits of decision accuracy.

Fundamentals And Applications Of Signal Detection Theory In Medical Imaging
SPIE Proceedings, 1986We present here a concise survey of the major themes running through the contemporary literature on the assessment of diagnostic imaging systems. These include the concept of the ROC curve, the ideal observer, the ideal observer signal-to-noise ratio constructed from the laboratory measurements, and complications arising from the application of the ...

Micro-Displacement Detection using Echo-Signal Cepstrum Analysis for Medical Diagnosis
2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2018The estimation of micro changes in morphological dimensions of thin biological structures (e.g. arterial wall, pulmonary pleura, sclera, etc) is a significant area of medical diagnosis where ultrasound has been applied more often each day; achieving higher resolutions on mechanical parameters which allow to provide information about biological tissue ...
