✍️ Sample ECHOCARDIOGRAM Questions & Answers
1. Which phantom is commonly used to evaluate spatial resolution in echocardiography systems?
The AIUM 100-mm test object is a standard phantom used to assess spatial resolution, dead zone, and range accuracy in ultrasound systems.
2. What is a 'change control process' in healthcare software management?
Change control ensures that software modifications are reviewed, approved, and documented to maintain system integrity and compliance.
3. The modified Bernoulli equation used in Doppler echocardiography is expressed as:
The simplified modified Bernoulli equation is ΔP = 4V², where V is peak velocity in m/s and ΔP is the pressure gradient in mmHg.
4. A sonographer notices that spectral Doppler waveforms have a 'noisy' baseline even when the sample volume is placed in a non-moving region. This artifact is most consistent with:
Noisy spectral baseline in a non-moving region suggests electronic noise or an inappropriately low wall filter that allows low-frequency clutter into the display.
5. A hospital's echo software project is delayed because requirements kept changing mid-development. Which SDLC model is best suited to accommodate frequent requirement changes?
Agile/Scrum embraces changing requirements through short iterative sprints and regular stakeholder collaboration.
6. In phased array transducer design, steering the ultrasound beam in different directions is achieved by:
Phased arrays steer the beam electronically by introducing precise time delays across individual transducer elements to create constructive interference at the desired angle.
