DEFINITION OF COLOR DOPPLER
IMAGING
CDI) is a non-  
invasive medical  
imaging technique 
 that combines  
traditional Doppler  
ultrasound with  
color mapping to  
visualize blood 
flow  in real-time.
PRINCIPLES
OF COLOR DOPPLER 
 IMAGING
Color Doppler imaging is a medical  
ultrasound technique that visualizes blood  
flow. It uses  the Doppler effect to detect  
movement of red blood cells, assigning color 
 to flow direction and speed. Principles  
include transmitting sound waves into the  
body, receiving reflected waves, and  
comparing frequency shifts. Flow towards 
the  probe is shown as red, away as blue.  
Brightness indicates speed. This non-
invasive  tool aids in diagnosing vascular 
conditions  and assessing organ perfusion.
TYPES OF CDI DISPLAYS
CDI (Centralized Display Interface)  
displays are used in aircraft to present  
essential flight information to pilots.  
There are several types of CDI displays:
Cathode Ray Tube (CRT) 
Display:  Liquid Crystal Display 
(LCD):
Active Matrix Liquid Crysta l
Display  (AMLCD):
Organic Light Emitting Diode (OLED):
Head-Up Display (HUD):.
Head-Mounted Display (HMD): 
 Enhanced Vision System 
(EVS):
APPLICATIONS 
COLOORF DOPPLER IMAGING
Color Doppler Imaging is a  valuable medical imaging technique that  
combines conventional ultrasound with Doppler technology to visualize  
blood flow in real time. Some applications include:
Cardiology: Assessing blood flow in the heart and detecting  
abnormalities like valvular disorders, congenital heart defects, and  
myocardial perfusion.
Vascular Medicine: Diagnosing blood vessel diseases, detecting blood  
clots, and evaluating varicose veins.
Obstetrics: Monitoring fetal blood flow and detecting placental  
abnormalities.
Oncology: Assessing tumor vascularity and guiding biopsies for cancer 
 diagnosis.
Neurology: Visualizing cerebral blood flow to detect strokes and other  
brain vascular conditions.
Color Doppler Imaging aids in diagnosing various conditions and 
enhances  the accuracy of treatment planning and monitoring.
