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.

Harmonics are created because:

Describe the phenomenon of attenuation in ultrasound imaging and its implications. How does attenuation affect image quality, and what methods are used to compensate for it?

Sound is classified as a __________ wave.

Discuss the operating principles of sonography, focusing on the pulse-echo technique and its significance in medical imaging. Explain how the echoes are used to create an image and the importance of echo strength and return time.
