  • Uncinate process

    A projection extending downward and backward from each lateral mass of the ethmoid bone that merges with the inferior nasal conchae.  

  • Ultrasound examination

    A diagnostic procedure in the field of medicine involves directing high-frequency sound waves towards a specific internal region of the body. As these sound waves bounce off internal structures, a computer analyzes the data to construct an image, providing visual information about the examined structures.  

  • Ultrasonographer

    The individual responsible for carrying out the radiologic procedure of ultrasound, which enables the visualization of deep structures within the body, is known as the ultrasound technologist.  

  • Ultrasound water path scanning

    Within the realm of scanning techniques, there exists a distinctive method that harnesses a pathway of water between the transducer and the object under examination. This particular approach enables the effective transmission of ultrasound waves and facilitates the scanning process with precision and accuracy.  

  • Useful voltage

    The segment of the sinusoidal waveform positioned above the horizontal axis represents one-half of the complete cycle. Conversely, the segment located below the horizontal line is referred to as the inverse voltage.  

  • Useful beam

    In radiology, the portion of the primary radiation that traverses the aperture, cone, or any other collimator is referred to as the transmitted beam.  

  • Ultracranio T

    Introducing the Picker skull radiographic/tomographic system, which incorporates a unique configuration where the x-ray tube traverses along the periphery of a sphere. Notably, the primary beam remains consistently directed towards the center throughout the movement.  

  • Ultrasound solid pattern

    Any recorded structure that exhibits the visual impression of encompassing echoes.  

  • Ultrasound single pass scanning

    A fundamental scanning technique that pertains to the manner in which the transducer is maneuvered over the patient’s body to generate a scan. The transducer is glided smoothly across the patient in a continuous motion, ensuring there are no abrupt movements or arcs created by the transducer.  

  • Ultrasound resolution

    The ability to discern two objects as separate and distinct entities is known as resolution. In the context of ultrasound scanning, two significant terms related to resolution are lateral resolution and axial resolution. These terms are crucial in determining the clarity and precision with which the ultrasound system can differentiate between objects in the lateral…
