Colour Doppler Ultrasound
Spectral Colour Doppler Ultrasound imaging:
CFM or Colour flow motion allows directional colour flow mapping of the blood particles by which, morphological colour maps in reference to probe orientation, and velocity distribution of the particles within averaged bands using appropriate Colour Doppler interpolation within the scanners and probes can be displayed in real time.
Most Scanners available from Pie data UK ltd can be used for diagnostic imaging of the dynamic blood, , observation of normal and restricted blood flow with is made possible. Additionally options for Advanced tissue Doppler can also be added to advanced ultrasound scanners with appropriate hardware and software configurations
Colour Doppler (Colour flow mapping, CFM):
As additional to conventional basic black and white ultrasound known as B mode ultrasound imaging, Colour Flow Mapping allows easier identifications of blood flow with direction and velocity within the arterial and vascular circularly system . Increasing scanners capabilities with the combination of grey scale soft tissue imaging , CFM scans adds to the overall diagnostic imaging of the Ultrasound examinations for the Patients with suspected cardiology or Vascular disease.
Colour Doppler ultrasound scanners with good colour sensitivities and probe range are available from Meditechnik Ltd
Only few Older Scanner Models these days needs Upgrading scanners to CFM licenses to allow real time ultrasound imaging capabilities of dynamic fluid flows. Most current up-to-date Colour Doppler scanners are installed with applications related ultrasound probes enables users to make use of soft tissue and blood flow of heart, vascular real time ultrasound diagnostic examinations of various conditions and anatomical structures including limbs and deeper anatomical structures, including detailed study of functionality of heart and related cardiovascular system, also allows quantitative measurements and calculations for identifications and assessments of health, restrictions blockages and flow directions within anatomical structures.
Depending on the presets and probes used, Colour mapping allows to identify distribution of fluids dynamics of blood velocities with morphological representations of fluid velocities in colour representing magnitude and directional colour flow mapping related to group of similar velocities present within the area of the interest.
Colour Doppler Applications:
A&E, Guided and Ultrasound access
Echo Cardiology
Vascular and DVT
Renal
Obs & Gyne
Oncology
Pelvic
Abdominal
And many more specialists diagnosis and assessments are made in hospitals by Ultrasonographers and trained doctors. Colour Doppler is useful mode of ultrasound examination, includes almost all areas of human anatomy where blood flow or restrictions and main or peripheral vessel’s vascular examinations are required
Very Basic yet, Important settings to obtain or create good Colour Doppler presets on an ultrasound scanners are..
Choice of probe for correct application.
Probe contact and position at an angle to flow direction.
Clear B -Mode cross sectional anatomical image ( with focus,depth, frequency, dynamic range….Power)
Velocity or PRF setting ( including colour base)
Colour gain
Colour frequency setting
Colour map of the choice
Colour quality ( Colour persistence, filters etc)
for further details always consult ultrasound scanners user and applications manuals.
