Sentence examples for transducer orientation from inspiring English sources

The most accurate measurements will be obtained when the ultrasound transducer is oriented so that endpoints of a fascicle lie on the ultrasound image plane and the image plane is oriented perpendicular to the aponeurosis, but little is known about how to find this optimal transducer orientation in the frequently-studied medial gastrocnemius muscle.

In the current study, we determined the optimal transducer orientation at 9 sites in the medial gastrocnemius muscle of 8 human subjects by calculating the angle of misalignment between three-dimensional muscle fascicles, reconstructed from diffusion tensor images, and the plane of a virtual ultrasound image.

In addition, our analysis investigates the advantage of increasing the cone angle by clustering which groups transducers by relaxing transducer orientation, and result shows that continuous clustering of seven transducers has the largest marginal contribution of 24%and41%1% to improve the qualified coverage in the non-regular NPP with hexagon placement and regular PP, respectively.

Movement in either a craniocaudal or mediolateral direction has different implications depending on transducer orientation.

Confusion of right and left heart chambers and major aortic arch vascular branches may occur due to improper transducer orientation, especially in the setting of congenital heart disease [110, 156].  .

Although Blaivas et al. have shown that novice ultrasound users were able to obtain vascular access faster using the short-axis approach in a vascular phantom model [2], Sierzenski et al. and Stone et al. have shown in vascular phantom models that novice ultrasound users had improved accuracy of identifying the needle tip with a long-axis ultrasound transducer orientation [13, 16].

Results indicate that situations may exist where liver and cardiac motion magnitudes lead to poor image quality, but optimized transducer orientations may help suppress motion artifacts if some a priori information concerning target motion characteristics is known.

The angle between transducer and orientation of the vessel was corrected.

Figure 3 illustrates respondents' preferences regarding selection of transducers, probe orientation and scanning modes.

Physicians will benefit from firm knowledge regarding the best choice of transducers, probe orientation and scanning modes in order to be able to achieve the highest possible diagnostic accuracy and reliable documentation of examination results without excessive use of time and resources.

Figure 3 Selection of transducers, probe orientations and scanning modes ( n = 78).
