A general for dealing with and moving snap shots and clinical statistics among computer
systems is:
A. Voxel
B. DICOM
C. HIPAA
D. VPN

snap shots using a DICOM format is:
A. VHS
B. DVD
C. USB
D. MOD
E. PACS - ANS-E. PACS
<PACS stands for Picture Archive and Communication System>
A type of sonographic imaging that transmits pulses of opposite section in rapid succession so
they may be cancelled out upon reception is named:
A. Pulse inversion harmonics
B. Compound imaging
C. Speckle reduction imaging
D. Tomographic imaging
E. Panoramic imaging - ANS-A. Pulse inversion harmonics
<Pulse inversion harmonics is an effective method to filter out the fundamental frequency
(transmitted frequency) and leave only the harmonic frequencies for display. It uses two pulses
of opposite polarity transmitted into the tissue in rapid succession. The received echoes from
the pulses are added together and will cancel out the transmitted frequency, leaving the
harmonics that were generated within the tissue>
A normal price for the obligation thing in diagnostic sonographic imaging is:
A. 80-a hundred%
B. 50-seventy five%
C. 25-forty five%
D. Five-20%
E. Zero.1-1% - ANS-E. 0.1-1%
<The duty factor is the time that the sound beam is actually on. With pulsed-wave imaging, the
fraction of time the sound is on is quite low because the transducer is listening most of the time>
A-mode display is maximum generally used for what sort of ultrasound imaging?
A. Small elements
B. Abdominal
C. Cardiac
D. Vascular
E. Ophthalmologic - ANS-E. Ophthalmologic
,All of the subsequent are limitations of M-mode scanning EXCEPT:
A. Information is received alongside only one line of sight
B. Motion lateral to the transducer is not displayed
C. Motion axial to the transducer isn't always displayed
D. The two-dimensional form of a shape isn't always shown
E. All of the above are boundaries of M-mode - ANS-C. Motion axial to the transducer isn't
always displayed
<With M-mode, motion axial to the transducer is not displayed through time, so this answer
choice is correct, because it does NOT represent a limitation of M-mode scanning>
An M-mode show is most commonly used for what type of ultrasound imaging?
A. Small elements
B. Abdominal
C. Cardiac
D. Vascular
E. Ophthalmologic - ANS-C. Cariac
Complete adverse interference of echo reflections will affect the show within the following way:
A. By developing bright white pixels
B. By developing black pixels
C. By creating dark grey pixels
D. By developing light gray pixels
E. None of the above - ANS-B. By creating black pixels
Digital-to-analog conversion of the ultrasound sign need to arise at what part of the imaging
technique?
A. Between the transducer and the receiver
B. Between the beam former and the transducer
C. Between the receiver and the experiment converter
D. Between the experiment converter and the display
E. Digital-to-analog conversion does now not occur within the ultrasound gadget - ANS-D.
Between the scan converter and the display
During a sonographic exam, you adjusted the following controls. Which one became maximum
probable to have affected the body fee?
A. Amplification
B. Transmit energy
, C. Scan depth
D. Time benefit reimbursement
E. Compression - ANS-C. Scan depth
<As the scanning depth (field of view) is increased, the system must decrease the PRF to avoid
range ambiguity. In other words, it must increase the time between words, it must increase the
time between pulses to account for the additional time it takes the ultrasound pulse to travel to
and from a reflector at the bottom of the field of view. As the PRF decreases, frame rate
decreases. It takes longer to fire the required number of pulses to create the image because the
time interval between pulses is greater>
Electronic noise is reduced in the ultrasound system with the aid of this approach:
A. Demodulation
B. Compensation
C. Rectification
D. Amplification
E. Rejection - ANS-E. Rejection
Electronic guidance is most commonly implemented to which of the following real-time
transducers?
