English term or phrase: elevation width
Kontekstas: "During Live 3D and Full Volume acquisition, you can change the elevation width and lateral size using the touch screen controls."

Kaip suprantu "elevation" yra "pjūvio storis" (http://images.slideplayer.com/14/4181928/slides/slide_33.jpg... Gal yra daugiau susidūrusių su radiologija, kas galėtų pakomentuoti tiek terminą "elevation", tiek "elevation width"?

Reference: Ultrasound image resolution

Reference information:
Ultrasound image resolution depends on beam width in the scan and elevation (section thickness) planes. The effect of the beam width in the elevation plane is usually not measured because calculation of the elevation dimension is tedious.

Spatial resolution

To understand how an image on the screen of an ultrasound system is produced, it is necessary to examine the features of a transducer and the ultrasound beams that it creates and receives. A transducer consists of many piezoelectric elements that convert electrical energy into sound energy and vice versa.Ultrasound, in the form of a pulsed beam, propagates from the surface of the transducer into soft tissue. Sound waves are absorbed in part by tissue but are also reflected back to the transducer where they are detected. Ultrasound scanners are able to process many pulsed beams instantly and thus create real-time images for diagnostic use. The ability of an ultrasound system to distinguish between two points at a particular depth in tissue, that is to say, axial resolution and lateral resolution, is determined predominantly by the transducer.

Axial resolution

Axial (also called longitudinal) resolution is the minimum distance that can be differentiated between two reflectors located parallel to the direction of ultrasound beam. Mathematically, it is equal to half the spatial pulse length. Axial resolution is high when the spatial pulse length is short.

Lateral resolution

Lateral resolution, with respect to an image containing pulses of ultrasound scanned across a plane of tissue, is the minimum distance that can be distinguished between two reflectors located perpendicular to the direction of the ultrasound beam. Lateral resolution is high when the width of the beam of ultrasound is narrow.

The width of the beam and hence lateral resolution varies with distance from the transducer, that is to say:

At the transducer, beam width is approximately equal to the width of the transducer.
Then, the beam converges to its narrowest width which is half the width of the transducer, at a perpendicular distance from the transducer called the near-zone length (Fig. 2a). The region of space subtended by the beam is called the near zone (Fresnel's zone).
At a distance greater than the near-zone length, that is to say in the far zone (Fraunhofer's zone), the beam diverges such that it becomes the width of the transducer, when the distance from the transducer to the reflector is twice the near-zone length. Here, lateral resolution decreases.

The dimension of the ultrasound beam and the transducer array are the origin of the beam width artifact or volume averaging artifact. When the ultrasound beam is wider than the diameter of the lesion being scanned, normal tissues which lie immediately adjacent to the lesion arc included within the beam width, and their echotexture is averaged in with that of the lesion.
Thus, what appears to be the echogenicity of the lesion is really that of the lesion plus the averaged normal tissues. Because of volume averaging, cystic lesions may falsely appear to be solid, and some subtle solid lesions may become impossible to distinguish from surrounding normal tissue and, therefore, not identified at all.
