Factors Influencing Axial Resolution The spatial pulse length is determined by the number of cycles within the pulse and its wavelength. 1. Number of Cycles within the Pulse: Applying a damping block behind the piezoelectric material prevents it from resonating for a long time, similar to placing a wet rag on a cymbal. Increasing dampening reduces …

Intensity is a crucial concept in ultrasound physics, particularly for understanding image quality and patient safety. Here's what you need to know about intensity: Definition and Units: Intensity describes the energy density within a sound beam. Its units are watts per square centimeter (W/cm²). Calculation: Intensity is calculated as beam power d…

Specular reflection is a fundamental phenomenon in ultrasound imaging that you need to understand: Definition: Specular reflection occurs when ultrasound energy strikes a very smooth surface and bounces back to the transducer, similar to how light reflects off a mirror. This bouncing back of sound energy is critical for creating the image displayed…

The duty factor is a significant parameter in ultrasound imaging, particularly concerning the characteristics of the emitted pulse and patient safety. Here's what you need to know about duty factor: Definition: The duty factor represents the proportion or percentage of time that an ultrasound pulse is actively propagating. It can be expressed as a …
