BALAYAGE TRIDIMENSIONNEL [7 records]

Record 1 2015-06-22

English

Subject field(s)
  • Centesis and Samplings
DEF

A procedure that uses a 3-dimensional scanning machine (ultrasound, CT [computed tomography] scan or MRI [magnetic resonance imaging]) to find the precise location of a tumour and remove a sample for examination under a microscope.

French

Domaine(s)
  • Ponctions et prélèvements
DEF

Intervention qui consiste à utiliser un appareil de radiodiagnostic pouvant effectuer un balayage tridimensionnel(appareil d’échographie, de TDM [tomodensitométrie] ou d’IRM [imagerie par résonance magnétique]) afin de localiser une tumeur avec précision et de prélever un échantillon qui sera examiné au microscope.

Record 2 2008-02-22

English

Subject field(s)
  • Applications of Automation
CONT

This paper proposes a novel multi-modal three-dimensional (3D) laser scanning system that combines high-accuracy 3D laser imaging, very high-resolution perspective color projection, and on-site geometric calibration of the intrinsic and extrinsic parameters.

French

Domaine(s)
  • Automatisation et applications
CONT

Cet article propose un nouveau système de balayage laser tridimensionnel(3D) multimodal qui combine l'imagerie laser 3D de haute précision, une projection des couleurs en perspective à très haute résolution et un étalonnage géométrique sur place des paramètres intrinsèques et extrinsèques.

Record 3 1999-03-17

English

Subject field(s)
  • Analytical Chemistry
DEF

The three-dimensional spectrum generated by scanning the emission spectrum at incremental steps of excitation wavelength...

OBS

The spectra are particularly useful for investigating samples containing more than one emitting species. Corrected EES are obtained if (a) the emission is corrected for instrumental response with wavelength, and (b) the exciting radiation flux in photons is held constant for all excitation wavelengths.

PHR

Fluorescence, phosphorescence excitation-emission spectrum.

French

Domaine(s)
  • Chimie analytique
DEF

Spectre tridimensionnel [...] engendré par le balayage du spectre d’émission en augmentant [graduellement] la longueur d’onde de l'excitation [...]

Record 4 1993-03-08

English

Subject field(s)
  • Air Defence
  • Signals (Military)
  • Radar, Radio Guidance and Goniometry
CONT

The Hughes Aircraft Co.'s ALR (Artillery Locating Radar) entry uses a three-dimensional radar that electronically scans the horizon with a pencil-shaped beam moving so fast that it forms a sensitive electronic barrier over any sector of the radar;s coverage.

French

Domaine(s)
  • Défense aérienne
  • Transmissions de campagne (Militaire)
  • Radar, radioguidage et radiogoniométrie
CONT

Hughes a réalisé un radar(tridimensionnel) à balayage électronique si rapide que son émission forme une véritable barrière dans la zone de couverture.

Subject field(s)
  • Computer Peripheral Equipment

French

Domaine(s)
  • Périphériques (Informatique)
CONT

D'autres équipes de chercheurs développent l'affichage holographique en temps réel : ainsi H.-J. Caufield d’Aerodyn Research met au point son "tube cathodique tridimensionnel" : les images en relief sont peintes à l'aide d’un dispositif de balayage à contrôle électronique, analogue à celui d’un tube cathodique.
