echo 1100 test 1

the form of reasoning by which one makes an educated guess based on facts describes

inductive reasoning

what is an educated guess based on clinical history findings

clinical hypothesis

what sonographic term means without echoes

anechoic

what sonographic term means having few echoes

hypoechoic

what sonographic term means having many echoes

hyperechoic

what is a structure that produces echoes

echogenic

having the same echogenicity

isoechoic

what would not be on a sonographer’s report

diagnosis

depth of returning echo is on the x-axis, while reflector strength is on the y-axis

a-mode

software utilized by the ultrasound machine that automatically obtains biometric measurements of the fetus

automated biometry

grayscale sonography with varying degrees of brightness

b-mode

doppler shift information presented as a color or hue superimposed over a grayscale image

color doppler imaging

an anomaly with which one is born

congenital anomalies

a doppler device that utilizes two elements, one that sends an one that listens

continuous wave doppler

the use of real time imaging in three dimensions

four dimensional ultrasound

a technique whereby the high quality images and specific strengths of different imaging modalities can be overlain and exploited

fusion imaging

an instrument based on the piezoelectric transducer that was designed to be used underwater for recording or listening to underwater sound

hydrophone

a diagnostic test in which an analysis of one part of the body is performed in order to obtain information about another part of the body

indirect testing

the element found within the face of the transducer to create ultrasound waves

lead zirconate titanate

mode that captures the movement of structures along a single scan line represented over time, with depth along the y-axis and time along the x-axis

m-mode

who recognized the pebble theory

Boethius

the process whereby a material, such as crystal, within an ultrasound transducer, generates electricity and changes shape when pressure is applied to it

piezoelectric effect

mode of doppler where it is not the shift itself that provides signal, but the strength of the shift

power doppler

doppler technique that uses pulses of sound to obtain doppler signals from a user specified depth

pulsed wave doppler

ultrasound imaging that allows continual imaging of the body as if it were watching a movie

real time scanners

non diagnostic imaging performed to provide the obstetric patient with keepsake photos and videos of the fetus

keepsake imaging

modes in triplex imaging

b-mode, spectral, color doppler
