In soft tissue a 7.5 mhz transducer with a two cycle pulse
will generate a spatial pulse length of: .4 mm
SPL is equal to the number of cycles in a pulse X the wavelength.

In which of the following media does sound propagate the
The null hypothesis, H , is an essential part of any research design, and is
always tested, even indirectly.
The simplistic definition of the null is as the opposite of the alternative hypothesis, H1, although the
principle is a little more complex than
2.4. Eye-movement analysis
Average horizontal eye velocity was computed as the slope of horizontal eye position over time
and was determined separately for the pursuit and fixation intervals of each trial. Prior to
calculating pursuit eye velocity, saccad
An electrooculograph (EOG) is a device that measures the voltage between two electrodes
placed on the face of a subject so it can detect eye movement.
This page describes a simple version of an EOG which can be used to detect whether the

Using the data recorded in Table 1, make a graph of the relationship between the force production and
the electrical activity by plotting the Force on the X-axis and the EMG Integral on the Y-axis. This
arrangement may seem counterintuitive, but in this p
If most subjects use their dominant forearm more than their non dominant forearm what does this
indicate about the degree of activation of motor units and these factors muscle fiber diameter?
If the subject uses their dominant forearm more, that forearm c
Ultrasound (US) is an imaging technology that uses high-frequency sound waves to
characterize tissue. It is a useful and flexible modality in medical imaging, and often provides
additional or unique characterization of tissues, compared with other modalit
