Computed tomography and pulmonary measurements.
Computed tomography (CT) was first developed to measure accurately radiographic density, rather than as a method of imaging. Although subsequent development concentrated on the imaging potential of the method, some recent studies have used the ability of the method to quantify radiographic density, to provide precise measurements of lung regions and infer differences in regional properties. CT ...
متن کاملExperimental measurements of the compressibility, temperature, and light absorption in dense shock-compressed gaseous deuterium
At present, advances in laser fusion and progress in the understanding of the structure and evolution of astrophysical objects have quickened interest in the study of thermodynamic and electrophysical properties of hydrogen the simplest and most abundant element in nature in the megabar pressure range. To achieve shock-compression megabar pressures, various methods of shock-wave excitation are ...
متن کاملBlue-light-induced infrared absorption in KNbO3
Owing to its high nonlinearity and low passive losses, KNbO3 has great potential as a medium for efficient frequency doubling and parametric oscillation." 2 For example, KNbO3 has been used successfully for the production of cw blue light by frequency doubling of a dye laser,3 doubling of a semiconductor diode laser,4 and nonlinear mixing of diode and Nd:YAG lasers.5 In recent work we observed ...
متن کاملInfrared absorption of gaseous CH2BrOO detected with a step-scan Fourier-transform absorption spectrometer.
CH2BrOO radicals were produced upon irradiation, with an excimer laser at 248 nm, of a flowing mixture of CH2Br2 and O2. A step-scan Fourier-transform spectrometer coupled with a multipass absorption cell was employed to record temporally resolved infrared (IR) absorption spectra of reaction intermediates. Transient absorption with origins at 1276.1, 1088.3, 961.0, and 884.9 cm(-1) are assigned...
متن کاملOptical Absorption Tomography for Carbon Dioxide Concentration Imaging
We consider the inverse problem of concentration imaging in chemical species tomography with limited data sets. The measurement setup involves simultaneous acquisition of near infrared wavelength-modulated spectroscopic measurements from a small number of pencil beams equally distributed among six projection angles surrounding the plume. We develop an approach for image reconstruction that invo...
