Abstract
The imaging of blood flow in blood vessels is the classic use of the Doppler effect in medicine. This method involves a transceiver ultrasonic probe which generates the acoustic signal in the form of a continuous wave which is reflected by moving biological components and returns with changed frequency. This effect can also be used to obtain the image of stationary tissue section, by moving the probe around the object. Such an imaging method is called Doppler Tomography (DT), or Continuous Wave Ultrasonic Tomography (CWUT). Currently, there is no comprehensive study of this method in the literature. This paper shows a simulation model which allows the reconstruction of the image consisting of infinitely small objects which evenly disperse the ultrasound wave. In order to assess the possibility of using DT in medicine, the obtained images were analyzed based on the parameters input to the reconstruction algorithm. Additionally, the exemplary waveform of a useful signal recorded of the real object of a small diameter is included.
