Explain the different sonographic imaging formats mentioned in Chapter 1, particularly focusing on the linear, sector, and combination formats. Discuss their applications and how they differ in terms of image production.

A 6 dB decrease corresponds to what reduction in intensity?

The dominant cause of attenuation in soft tissue is:

What determines the brightness of a dot in the pulse-echo image?

Which describes the number of pulses per second?

Scattering allows:

What unit is used for frequency in sonography?

When sound hits a boundary between two media perpendicularly, what determines reflection vs. transmission?

What determines propagation speed in tissue?

The Doppler effect measures:
