Effect of Selected Parameters on Imaging Quality in Doppler Tomography

Applied Sciences
Doppler tomography (DT) is a relatively new method that allows the imaging of cross-sections of an object. The method uses a two-transducer ultrasound probe that moves around or along the object in a specific way. Image reconstruction is performed on the
