Estimation of true flow velocity using ultrasound
Ultrasound colour Doppler is used for estimation of flow velocity in blood vessels. The quantified flow velocity is dependent on the orientation of the ultrasound propagation path relative to the orientation of the investigated blood vessel. There are different methods that can be used for estimation of true flow velocities. One approach is to do Doppler measurements of the blood vessel from different angles. The flow velocity obtained from at least two different angles can be used to provide a more correct estimate of the true flow velocity.
Aim:
- Compare a novel suggested simple method to other methods for estimation of true flow velocity (litterature study)
- Implement the suggested method in Matlab
- Perform laboratory measurements of flow
- Analyse the performance of the method
Qualifications:
- Matlab programming, digital signal processing. Knowledge of acoustics and ultrasound is also advantageous.
