What will result in the best axial resolution long pulse length short pulse length low pulse repetition frequency or high pulsed repetition frequency?
== == In diagnostic ultrasound axial resolution is influenced by a number of factors including transmission pulse length and frequency of the probe. For best axial resolution short pulses are used - long pulses can potentially improve the signal to noise ratio but their use often results in "range side lobes", effectively a reduction in axial resolution. Pulse repetition frequency (PRF) is a separate issue to axial resolution however high frequency probes are able to have a higher PRF (resulting in higher frame rates) than low frequency probes due to the higher rate of absorption of the higher frequency signals.
Which action can improve axial resolution of a displayed image?
Increasing the numerical aperture of the imaging system can improve the axial resolution of a displayed image. A higher numerical aperture allows the system to distinguish finer details in the axial direction. Additionally, using a shorter wavelength light source can also help improve axial resolution.
Which resolution is diminished when using fundamental harmonic imaging rather than pulse inversion harmonic imaging?
AXIAL
What is axial direction in wood?
Axial direction in wood means its longitudinal direction (the height of the tree when it was growing). Engineers look at this as the direction that cylinder spins on its axis, if log were a roller, the axial direct ion would be along its length.
What is axial direction?
It is the direction in line with (parallel to) the axis of the part. If you have a cylindrical shaft, for example, the axial direction runs along the length thru the center of the circular ends.
Which one of the following words is related to the axial skeleton Patella Cranium Metacarpal Brachial?
The word related to the axial skeleton is "Cranium." The cranium is part of the skull, which is a key component of the axial skeleton that supports and protects the brain. In contrast, the patella, metacarpal, and brachial refer to parts of the appendicular skeleton.
What is rotation length of earth?
The earth executes one complete axial rotation in 23hours 56minutes 4seconds. (rounded)

What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
When the helical compression spring is subjected to axial compressive force the type of induced in the spring wire is?
When a helical compression spring is subjected to axial compressive force, the type of stress induced in the spring wire is primarily compressive stress. This stress is caused by the load that the spring is supporting, leading to a reduction in the length of the spring along its axial direction.
Is the vertebra axial or appendicular?
It is axial.
What is axial thrust?
Axial Thrust is a force that is generated in an axial direction which is by definition along the shaft
