2. Carotid ultrasonography - Wikipedia

   en.wikipedia.org/wiki/Carotid_ultrasonography

   During carotid duplex evaluation, the 2D B-mode structural image is superimposed with the doppler flow data, which provides a more realistic anatomical assessment. [2] B-mode ultrasound is able to assess the structure of the carotid arteries and can identify areas of stenosis. B-mode is used identify stenotic lesions and to assess the ...

3. Doppler ultrasonography - Wikipedia

   en.wikipedia.org/wiki/Doppler_ultrasonography

   Duplex scan of the common carotid artery. Colour Doppler shows the direction of the blood flow in red or blue (either towards or away from the transducer). Meanwhile, spectral Doppler not only shows the direction of blood flow, it also shows the phases (pulsatility) and acceleration of the blood flow.

4. Medical ultrasound - Wikipedia

   en.wikipedia.org/wiki/Medical_ultrasound

   Duplex scan of the common carotid artery. Doppler ultrasonography employs the Doppler effect to assess whether structures (usually blood) [57] [60] are moving towards or away from the probe, and their relative velocity. By calculating the frequency shift of a particular sample volume, flow in an artery or a jet of blood flow over a heart valve ...

5. Carotid artery stenosis - Wikipedia

   en.wikipedia.org/wiki/Carotid_artery_stenosis

   70 percent stenosis of the right internal carotid artery as seen by ultrasound. Arrow marks the lumen of the artery. CT image of a 70 percent stenosis of the right internal carotid artery. Carotid artery stenosis is usually diagnosed by color flow duplex ultrasound scan of the carotid arteries in the neck.

6. Ultrasonography of chronic venous insufficiency of the legs

   en.wikipedia.org/wiki/Ultrasonography_of_chronic...

   Doppler measurements which trace the echoes of the generated soundwaves received by the probe, enable the direction and velocity of the blood flow to be depicted. The overlay of color onto the Doppler information lets these images be seen more clearly. [8] The choice of a probe will depend on the depth needed to be studied.

7. Transcranial Doppler - Wikipedia

   en.wikipedia.org/wiki/Transcranial_Doppler

   The tests are often used in conjunction with other tests such as MRI, MRA, carotid duplex ultrasound and CT scans. The tests are also used for research in cognitive neuroscience (see Functional transcranial Doppler, below).

8. Medical optical imaging - Wikipedia

   en.wikipedia.org/wiki/Medical_optical_imaging

   Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance.Examples include optical microscopy, spectroscopy, endoscopy, scanning laser ophthalmoscopy, laser Doppler imaging, optical coherence tomography, and transdermal optical imaging.

9. Doppler echocardiography - Wikipedia

   en.wikipedia.org/wiki/Doppler_echocardiography

   Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect .
