Photoacoustic tomography with a single detector in a reverberant cavity.
In conventional biomedical photoacoustic tomography (PAT), ultrasonic pulses generated through the absorption of nanosecond pulses of near-infrared light are recorded over an array of detectors and used to recover an image of the initial acoustic pressure distribution within soft tissue. This image is related to the tissue optical coefficients and therefore carries information about the tissue ...
متن کاملPositron tomography and nuclear magnetic resonance imaging.
Noninvasive imaging methods for medical diagnosis and biological investigations, have evolved from qualitative radiological techniques to quantitative methods of measuring biochemical and physiological processes in human body. In particular, new developments in emission tomography, nuclear magnetic resonance imaging, and in vivo spectroscopy offer new horizons for medical research and clinical ...
متن کاملBimodal magnetic resonance imaging-computed tomography nanoprobes: A Review
Bimodal imaging combines two imaging modalities in order to benefit from their advantages and compensate the limitations of each modality. This technique could accurately detect diseases for diagnostic purposes. Nanoparticles simultaneously offer diagnostic data via various imaging modalities owing to their unique properties. Moreover, bimodal nanoprobes could be incorporated into theranostic s...
متن کاملNuclear magnetic resonance vs. computed tomography.
The diffusion of computed tomographic (CT) scanners into the health care system, after an initially torrid start, eased up considerably once the diagnostic capabilities of the revolutionary devices were recognized. In the estab lishment of the scanners in the medical community , comments such as " definitive and conc lusive diagnosis ," " value clearly demonstrated ," and " prevention of deaths...
متن کاملAssessment of X-Ray Crosstalk in a Computed Tomography Scanner with Small Detector Elements Using Monte Carlo Method
Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...
