Do transducer angulation, focal zona and object depth influence the accuracy of ultrasound measurements? An in vitro study

Adequate understanding of acoustic properties and ultrasound system operation is essential to obtain high-resolution images of structures of interest, thereby increasing diagnostic accuracy and avoiding inadvertent injury to critical structures during image-guided procedures. The aim of this study was to evaluate the influence of probe angulation, focal zone position, and object depth on measurement accuracy in US imaging.
