Ultrasound
A medical imaging technique that uses high-frequency sound waves to create images of organs and structures inside the body.
Transducer
An energy converter that emits and receives sound waves during ultrasound imaging.
A Mode (Amplitude Mode)
An early ultrasound imaging mode that displays the amplitude of reflected sound waves, indicating distance.
2D Ultrasound
Two-dimensional imaging that provides cross-sectional images of tissues and organs.
Frequency in Ultrasound
The number of sound wave cycles per second; higher frequency allows better resolution but less penetration.
Vascular Ultrasound
Ultrasound imaging focused on blood vessels and blood flow.
Matric Fetal Medicine
A specialized field of ultrasound focused on monitoring the health of the fetus.
Bucky
A device that holds the image receptor and aids in the taking of radiographs.
Positioning Terms
Terms used to describe the orientation of a patient in relation to the imaging device.
Dorsal Recumbent Position
A position where a patient lies on their back, facing upwards.
Fowler Position
A position where the patient lies on their back with the head elevated.
Supine Position
A position where a patient lies flat on their back.
Oblique Position
A position where the body is angled between supine and lateral.
AP Projection
Anteroposterior projection where the X-ray beam enters from the front and exits through the back.
PA Projection
Posteroanterior projection where the X-ray beam enters from the back and exits through the front.
Lateral Projection
Projection where the X-ray beam enters from one side of the body and exits out the other.
Transverse Plane
A horizontal plane that divides the body into superior and inferior parts.
Sagittal Plane
A vertical plane that divides the body into left and right parts.
Coronal Plane
A vertical plane that divides the body into anterior and posterior parts.
