Vascular Sonography I and physics introduction

divides the body into right and left portions, aka longitudunal

What is the image orientation of the sagittal scan plane?

Divides the body into superior and inferior portions

What is the image orientation of the transverse scan plane?

Divides the body into anterior and posterior portions.

Describes an organ or tissue that is capable of producing echoes used to describe tissue texture, describes brightness

Portion of the image that is echo free, also used as echolucent or sonolucent

This is a portion of image echoes brighter than surrounding tissue brighter than normal for specific tissue or organs

Why do hyperechoic images occur?

portion of image echoes not as bright as surrounding tissue or less bright than usual for a specific organ tissue

Why do you get hypoechoic images?

structure of equal echo density

image of echoes of equal density

several echo characteristics (kidneys)

What three definitions are used to describe internal echo patterns?

What are the 3 requirements of a to call something cystic?

What are the 3 requirements to call something solid?

contains both anechoic and echogenic areas echogenicity will vary with the make up of the mass

This is the change in frequency of an echo relative to motion between the sound source and the reciever

This is the actual changed Frequency

Where is the ideal doppler shift obtained?

Tons of lines that go together to make up a doppler waveform. Each line makes up a doppler reading
