Ultrasound

A medical imaging technique that uses high-frequency sound waves to create images of organs and structures inside the body.

2
New cards

Transducer

An energy converter that emits and receives sound waves during ultrasound imaging.

3
New cards

A Mode (Amplitude Mode)

An early ultrasound imaging mode that displays the amplitude of reflected sound waves, indicating distance.

4
New cards

2D Ultrasound

Two-dimensional imaging that provides cross-sectional images of tissues and organs.

5
New cards

Frequency in Ultrasound

The number of sound wave cycles per second; higher frequency allows better resolution but less penetration.

6
New cards

Vascular Ultrasound

Ultrasound imaging focused on blood vessels and blood flow.

7
New cards

Matric Fetal Medicine

A specialized field of ultrasound focused on monitoring the health of the fetus.

8
New cards

Bucky

A device that holds the image receptor and aids in the taking of radiographs.

11
New cards

Fowler Position

A position where the patient lies on their back with the head elevated.

12
New cards

Supine Position

A position where a patient lies flat on their back.

13

Oblique Position

A position where the body is angled between supine and lateral.

14
New cards

AP Projection

Anteroposterior projection where the X-ray beam enters from the front and exits through the back.

15
New cards

PA Projection

Posteroanterior projection where the X-ray beam enters from the back and exits through the front.

16
New cards

Lateral Projection

Projection where the X-ray beam enters from one side of the body and exits out the other.

17
New cards

Transverse Plane

A horizontal plane that divides the body into superior and inferior parts.
