Figure 2From: Can echocardiographic particle image velocimetry correctly detect motion patterns as they occur in blood inside heart chambers? A validation study using moving phantoms Acquisition and analysis of phantom data. (A) In the string phantom, the direction of the string motion was set during acquisition in steps of 15° relative to the ultrasound beam. (B) In the rotating phantom, different insonation angles could be obtained during post-processing by placing the sample volume of the post-processing program at different pre-defined points around the circumference of the phantom.
