Phantom
Protocols for medical sonography examinations have been adapted by the: - Answers -
American College of Radiology and American Institute of Ultrasound Medicine
Quality assurance programs provide assessment of: - Answers -Image quality
The hydrophone measures: - Answers -Pulse repetition period
Tissue-mimicking phantoms are unable to evaluate: - Answers -Direction of flow
The width of the sound beam determines the: - Answers -Lateral resolution
Development of a quality assurance program ensures: - Answers -Image consistency
The dead zone is located: - Answers -Near the transducer face
The ability of a diagnostic technique to identify the presence of genuine disease is
termed: - Answers -Sensitivity
The ability to identify correctly the absence of disease is termed: - Answers -Specificity
Accuracy of a diagnostic test is most precisely defined as the: - Answers -Quality of
being near to the true value
Tissue-mimicking phantoms cannot evaluate: - Answers -Blood flow
Which of the following testing devices can simulate pulsatile or retrograde flow ? -
Answers -Moving string phantom
You are using a tissue equivalent phantom. At a particular depth, reflections are no
longer observed. What are you evaluating? - Answers -Sensitivity
Using a tissue equivalent phantom, two pins at depth of 2 cm and 10 cm are imaged.
On the systems display, you measure the distance between the two reflections created
by these pins. What are evaluating? - Answers -Range calibration
Using a tissue equivalent phantom, a sonographer adjusts the gain so that reflections
on the display change from fully bright to barely visible. What is the sonographer
evaluating? - Answers -Sensitivity
Which of the following phantoms can be used to evaluate performance Doppler
systems? - Answers -String phantom
