1Soft tissue propagation speed of ultrasound is assumed by echocardiography systems to be:

A.1450 m/s

B.1500 m/s

C.1540 m/s

D.1620 m/s

Explanation: Diagnostic ultrasound systems assume a fixed soft-tissue propagation speed of 1540 m/s. This value drives the depth (range) calculation: depth = (speed × time) / 2. When tissue speed differs from this assumption (e.g., fat ~1450 m/s), range artifacts can occur.

2Which formula correctly relates the speed of sound (c), frequency (f), and wavelength (λ)?

A.c = f / λ

B.c = f × λ

C.λ = c × f

D.f = c × λ

Explanation: The fundamental wave equation is c = f × λ. In tissue, c is essentially fixed (~1540 m/s), so increasing the transducer frequency proportionally decreases the wavelength. Shorter wavelengths produce better axial resolution but less depth penetration.

3Axial resolution is determined primarily by:

A.Beam width

B.Spatial pulse length

C.Pulse repetition frequency

D.Frame rate

Explanation: Axial (depth) resolution equals approximately one-half the spatial pulse length (SPL). Higher transducer frequencies and shorter pulses (fewer cycles per pulse) yield smaller SPL and better axial resolution.

4Lateral resolution is best at which location along the ultrasound beam?

A.Near field (Fresnel zone)

B.Focal zone

C.Far field (Fraunhofer zone)

D.Skin surface

Explanation: Lateral resolution depends on beam width, which is narrowest at the focal zone where the beam is most converged. Operators should place the focus at the level of the structure of interest to maximize lateral resolution.

5The Nyquist limit equals:

A.The pulse repetition frequency (PRF)

B.Half the PRF

C.Twice the PRF

D.The transducer frequency

Explanation: In pulsed-wave Doppler, the Nyquist limit equals one-half the PRF. Velocities exceeding this limit alias and wrap to the opposite end of the spectrum. CW Doppler is not bound by the Nyquist limit and can measure very high velocities.

6A pulsed-wave Doppler tracing shows aliasing across the baseline. The single best initial maneuver is to:

A.Decrease the transducer frequency

B.Shift the baseline (zero shift)

C.Increase the gain

D.Switch to color Doppler

Explanation: Baseline shifting gives the entire usable scale to the direction of interest, effectively doubling the depictable velocity in that direction without changing PRF. If aliasing persists, increasing PRF (decreasing depth, switching to high-PRF, or moving to CW Doppler) is next.

7Continuous-wave Doppler is preferred over pulsed-wave Doppler when:

A.Sampling at a specific depth is needed

B.Range resolution is essential

C.Measuring high velocities (e.g., AS jets)

D.Imaging slow venous flow

Explanation: Continuous-wave Doppler can measure very high velocities without aliasing because there is no PRF-based Nyquist limit. The trade-off is range ambiguity — CW samples all depths along the cursor.

8Tissue Doppler imaging (TDI) measures:

A.High-velocity, low-amplitude blood flow

B.Low-velocity, high-amplitude myocardial motion

C.Acoustic impedance differences

D.Backscatter intensity

Explanation: TDI applies low-pass filters and reduced gain to capture low-velocity (typically <20 cm/s), high-amplitude signals from the myocardial wall rather than blood. TDI provides the e' velocity used in the diastolic algorithm and S' for RV/LV systolic function.

9Speckle-tracking strain imaging is most often reported as:

A.Absolute peak velocity

B.Global longitudinal strain (GLS), a negative percentage

C.Color M-mode propagation slope

D.Tissue acoustic impedance

Explanation: Speckle-tracking GLS measures the percent shortening of the LV in the long axis. Normal values are typically more negative than -18% to -20%. GLS is more sensitive than EF for early subclinical dysfunction (e.g., chemotherapy-related cardiotoxicity, amyloid).

10Tissue harmonic imaging improves image quality primarily by:

A.Increasing the fundamental transmit frequency

B.Receiving signals at twice the transmit frequency to reduce near-field artifact

C.Eliminating reverberation through compounding

D.Using compound Doppler shifts

Explanation: Tissue harmonic imaging transmits at a fundamental frequency (e.g., 2 MHz) and receives at the second harmonic (e.g., 4 MHz). Harmonics develop deeper in tissue, so near-field clutter, side lobes, and reverberation are reduced, improving endocardial border definition.

About the CCI RCS Adult Echo Exam

The CCI Registered Cardiac Sonographer (RCS) credential validates adult echocardiography competency and is a recognized vendor alternative to the ARDMS RDCS. The exam covers ultrasound physics, cardiac anatomy and views, chamber quantitation, diastolic function, valvular heart disease, cardiomyopathies, ischemic disease, pericardial disease, and adult congenital findings.

CCI RCS Adult Echo Study Tips from Top Performers

1Memorize the simplified Bernoulli equation (ΔP = 4V²) and continuity equation (AVA = LVOT area × LVOT VTI / AV VTI)

2Practice the ASE/EACVI 2016 diastolic algorithm: E/A, e' septal/lateral, E/e', LAVi, TR velocity

3Drill the 17-segment AHA model and which coronary artery supplies which segment

4Know severity thresholds: severe AS (Vmax ≥4 m/s, mean ≥40 mmHg, AVA <1.0 cm²); severe MR (EROA ≥0.40 cm², RVol ≥60 mL)

5Understand tamponade signs (RA collapse in late diastole, RV collapse in early diastole, IVC plethora, mitral inflow >25% respiratory variation)

6Distinguish constriction (respirophasic septal shift, expiratory hepatic vein reversal) from restriction (E/e' very high, biatrial enlargement)

Frequently Asked Questions

How is the CCI RCS different from the ARDMS RDCS?

Both credentials validate adult echocardiography competency. CCI RCS and ARDMS RDCS-AE cover the same scope of adult echo practice but are issued by different vendors. Many employers accept either; some clinicians hold both.

How many questions are on the CCI RCS exam?

The CCI RCS exam contains 170 multiple-choice questions including unscored pretest items. The exam window is 3 hours.

What score do I need to pass the RCS?

CCI specialty exams use a scaled passing score of 670 on a 300-900 scale. Raw scores are converted to a scaled score to account for slight variations in form difficulty across testing windows.

What are the CCI RCS prerequisites?

CCI offers multiple eligibility prerequisites: graduates of an accredited cardiovascular technology program, currently registered cardiac sonographers (RDCS) with documented experience, or candidates with a structured combination of education and clinical hours in adult echocardiography.

How much does the CCI RCS exam cost?

The CCI RCS exam fee is $365 as of 2026. There may be additional retake or rescheduling fees. CCI also offers a renewal cycle of 3 years requiring continuing education credits.

Where do I take the CCI RCS exam?

CCI exams are delivered through Pearson VUE testing centers. Online proctored options have historically been more limited than at ARDMS; check the CCI candidate handbook for current scheduling rules.
