In medical ultrasound physics, pulse duration refers to the actual time a single ultrasound pulse is active, from the beginning to the end of its transmission. Measured in microseconds, it’s determined by the number of cycles within the pulse multiplied by the period of each cycle. A shorter pulse duration enhances axial resolution, allowing for better distinction between structures positioned along the ultrasound beam’s path.
Optimizing pulse duration is crucial for high-quality diagnostic ultrasound imaging, impacting the clarity and detail of anatomical visualizations. Shorter pulses lead to improved image fidelity, which is essential for precise medical assessments and accurate pathology detection. Understanding this physical parameter is key for sonographers and radiologists seeking to master ultrasound physics and enhance diagnostic capabilities.
