With the characteristics of digital memories, regarding the highest number stored, if the
decimal is 63, which of the following would be considered correct for the binary? -
ANSWER - Regarding the highest number stored, if the decimal is 63 the binary would
be: 111111.Find this by dividing 63 by 2 and recording the remainder.
63/2 is 31 with a remainder of 1
31/2 is 15 with a remainder of 1
15/2 is 7 with a remainder of 1
7/2 is 3 with a remainder of 1
3/2 is 1 with a remainder of 1
2/1 is 0 with a remainder of 1
Therefore 63 in binary is 111111
Which of the following terms can also be used interchangeably with transverse wave? -
ANSWER - The terms SHEER WAVE and TRANSVERSE wave can be used
interchangeably. If there is a sound wave in which the particle motion is perpendicular to
the direction of wave travel, it would be considered a transverse wave (sheer wave).
Which of the following could be used to help prevent issues when advancing the guide
wireless bidirectionnally steerable catheter into the heart? Chest-x-rays Fluoroscopy
Cardiac catheterization Using a short sheath - ANSWER - Fluoroscopy
When this guide wireless bidirectionally steerable catheter is being inserted into the
heart, a fluoroscopy can be used to help prevent issues. Another practical tip for
preventing issues could be using a long-access sheath to help avoid injuring the pelvic
veins during navigation.
The Windkessel effect would result in which of the following occurring? 1 Continued flow
in the forward direction
2 Intermittent flow in the forward direction
3 No flow in the forward direction
4 A temporary forward flow followed by a backward flow - ANSWER - Continued flow in
the forward direction
The Windkessel effect would result in the continued flow in the forward direction.
The closure of the aortic valve prevents the backward flow of blood into the heart.
Which of the following would be considered a function of the signal processor?
1 Digitization 2 Time gain compensation 3 Amplitude detection
4 Echoes versus pulsation - ANSWER - Amplitude detection
There are 3 functions of the signal processor:
Bandpass filtering, Amplitude detection, Compression
,In order to increase the number of foci, which of the following would the PRF need to
do?
1. Decrease 2. Remain the same 3. Increase 4. Double - ANSWER - Increase
In order to increase the number of foci, the PRF needs to increase. PRF stands for
pulse repetition frequency.
The vector array would be considered the combination of which of the following?
1. Crystal array operations
2 Phased array operations
3 Linear array operations
4 Both B and C - ANSWER - Both B and C
The vector array would be considered the combination of:
Phased array operations
Linear array operations
This will present a sector display which has a nonzero width at the top
Each pixel has how many bits associated with it?
10
4
6
12 - ANSWER - 4
A pixel is a square picture element.
Each bit has 4 bits associated with it.
A bit is considered a binary digit.
There are 4 checkerboards back to back with the 4 binary-digit memories.
In addition to the patient's diastolic function, the left atrial size would also be a predictor
of risk for all but which of the following?
1. Renal failure
2 Stroke
3 Cardiac events
4 Atrial fibrillation - ANSWER - Renal failure
The size of the patient's left atrial would be considered a predictor of risk for:
Diastolic function
Stroke
Atrial fibrillation
Cardiac events
Of the following, which would typically not be a systemic condition that would be
associated with cardiovascular abnormalities?
1. Pregnancy
2 Diabetes mellitus
3 Thyroid disease
4 Chronic renal insufficiency - ANSWER - Thyroid disease
Some of the conditions that can typically be a systemic condition that is associated with
cardiovascular abnormalities would include:
, Diabetes mellitus
Chronic renal insufficiency
HypertensionPregnancy
Tricuspid Atresia - ANSWER - Absence of tricuspid valve and hypoplastic RV; requires
both ASD and VSD for viability.
ascites - ANSWER - accumulation of fluid in the peritoneal cavity
What effect would inspiration have on the mitral valve velocity? - ANSWER - With
inspiration, the mitral valve velocity would increase. Peak mitral inflow velocity can be
used to predict mitral regurgitation severity.
During Inspiration, what increases and decreases - ANSWER - RA pressure drops, so
more venous return. More blood to lungs, causes less to return to LA, so stroke Volume
is lower.
Which heart chamber is most Anterior? - ANSWER - right ventricle
Vessels that come off Aortic Arch, in order? - ANSWER - The innominate vessel which
is same as brachiocephalic artery.
The left common carotid artery
The left subclavian artery which is the distal
Which 2 valves are semilunar? - ANSWER - aortic and pulmonary
3 basic kinds of problems with heart valves - ANSWER - 1. Atresia
2. Stenosis
3. Regurgitation
aortic aneurysm causes pain where? - ANSWER - Lower back
Also lower with abdominal.
Chest is caused by Thoracic aneurysm
3 types of aortic aneurysms - ANSWER - Thoracic, abdominal, and thoracic-abdominal
LA size is predictor of risk for? - ANSWER - Atrial Fib
3 aspects of Image resolution - ANSWER - 1. Detail
2. Temporal
3. Contrast
PRF formula - ANSWER - PRF (Hz) = n x LPF x FR (hz)
Angiosarcoma usually affect - ANSWER - Seen usually in RA.
Commonly affect:
