  • Patent number: 10219788
    Abstract: Doppler ultrasound systems are valuable diagnostic tool for investigation of vascular blood flow pattern and velocity. Error in blood velocity measurements made by doppler instruments will cause probable misdiagnosis in clinical practice. There are different phantom designs for evaluation of the performance and QC of doppler ultrasonography systems. Among different phantom designs the string phantom because of their ability to precise calculation of target velocity were widely used by different investigators. Generally this type of phantom consists of a moving string with known velocity as a target inside a water tank to mimic blood flow inside the vessels of the body. We designed a new string phantom with three dependently adjustable parameters including target velocity, target angle and target depth.
