Read Abstract

Pulse oximetry technique is a non invasive method useful to monitor the quantity of oxygen in hemoglobin, used in medical diagnosis and clinical decision-making. It is based on the ratio between the red and infrared light absorbance corresponding to the oxygenated (HbO₂) and non-oxygenated (Hb) state of the hemoglobin. We develop the mathematical model to obtain the oxygen saturation value observing that it depends on four known parameters: two transillumination values assessed at the common pulse oximetry wavelengths (λ₁ = 660 nm y λ₂ = 940 nm), and the extinction coefficients for the oxy- and deoxy-hemoglobin at these given wavelengths. Analyzing the extinction curves for oxy- and deoxy-hemoglobin we note that at λ equal to 660 nm the HbO₂ component almost does not contribute to the attenuation of incidance when we transilluminate tissue (7.479x10^-5 cm^-1M^-1). In this case is the Hb component that gives the significant attenuation value (7.863x10^-4 cm^-1M^-1). In 940 nm the extinction coefficient of the Hb is 2.589x10^-5 cm^-1M^-1 and we can ignore it when we count attenuation. At this λ we assume that the pulsate component is only affected by the HbO₂ (2.099x10^-4 cm^-1M^-1). This analysis of hemoglobin extinction coefficients in the absorption curves highlights the signal to noise ratio between these two oxygen dependent elements. We are interested in accentuate the better contrast interval (λ pair), where this signal-to-noise ratio is higher, looking for more transillumination information and more precise SO₂ value. We propose to use a transillumination waveform simulator to study the different effects (respiration, artifact body movement, absorption, low perfusion, etc) presented in complex physiological signals and to know the optical path-integrated behavior when we transilluminate tissue. This is practical for acquisition and processing transillumination signals. The present work is the first part of a λ selection method to guaratee the optimum S/N for measurements in blood using pulse oximetry and spectroscopic techniques at near infrared.

Course Instructor

SC798: Practical Radiometry

This course will provide attendees with a basic working knowledge of radiometric concepts. Radiometry deals with generation, propagation, modification, and detection of radiation. It is based on the generation of radiation in matter, propagation through a partially transmissive 3-dimensional space, and detection in matter. Many practical and useful examples are included throughout. While the geometrical concepts employed in radiometry often imply detailed calculations, useful and reasonable approximations will be emphasized. The following topics will be included: • Concepts of geometrical optics (ray, beam, optical system, object and image similarity) • Generation of radiation: sources • Detection of radiation • Spatial extent of sources: point and extended sources • Geometry of sources and detectors • Directional properties of sources and detectors • Angle, projected angle, solid angle, and projected solid angle • Spectral and radiative characteristics of sources (power) • Spectral characteristics of sources and detectors • Derived radiometric quantities and units: radiance, exitance (emittance), incidence (irradiance), intensity • Blackbody radiators and emissivity • Planck´s law, Wien´s law, Stefan-Boltzmann´s law, and Kirchoff´s law • Stray light, and configuration factors • Two invariants of optical systems: throughput (etendue) and radiance • Loss of information between plane 1 and plane 2 • Radiance at the sensor • Detected radiance

SC174: Multispectral Image Processing

Multispectral imagery contains a wealth of information beyond panchromatic imagery. This course describes and evaluates computer processing techniques used to extract information from multispectral imagery. The emphasis is on earth remote sensing, but the techniques discussed apply to any multispectral imagery.
