Color Doppler imaging of cervicocephalic fibromuscular dysplasia

open access: yesCardiovascular Ultrasound, 2004
Background Fibromuscular dysplasia (FMD) is a possible cause of stroke, especially in middle-aged women. However, only few reports are available on ultrasonographic detection and monitoring.

Update on Color Flow Imaging in Obstetrics

open access: yesLife, 2022
Color flow imaging (CFI), being non-invasive, is commonly used in obstetrics to study the fetal and placental circulations. The conventional CFI modes include color Doppler flow imaging (CDFI) and power Doppler imaging (PDI).

Single camera 3D planar velocity measurements using imaging fibre bundles and two frequency Planar Doppler Velocimetry (2nu-PDV) [PDF]

open access: yes, 2005
3D planar flow-field measurements are made using multiple imaging fibre bundles to port different views of the measurement plane, defined by a laser light sheet, to a CCD camera.

Acousto-optic frequency switching for single-camera planar Doppler velocimetry [PDF]

open access: yes, 2001
A single-camera Planar Doppler velocimetry system has been demonstrated, in which illumination beams at two closely-spaced optical frequencies are derived from a single Argon-ion laser.

Single camera three component planar velocity measurements, using two frequency Planar Doppler Velocimetry (2v-PDV) (2005) [PDF]

open access: yes, 2005
The work presented here describes a method that allows three component velocity measurements to be made, quickly and non-intrusively, across a plane in a flow defined by a laser light sheet. The method, two frequency planar Doppler Velocimetry (2v-PDV)

Single camera three component planar velocity measurements using two-frequency planar Doppler velocimetry (2ν-PDV) (2012) [PDF]

open access: yes, 2006
Two-frequency planar Doppler velocimetry (2ν-PDV) is used in conjunction with imaging fibre bundles to make time-averaged three component velocity measurements using a single CCD camera and iodine cell. In this scheme the flow is sequentially illuminated
