| Term | Definition |
|---|---|
| When is Central Ray Angulation use? | It is used to best demonstrate the anatomic details free from superimposition by overlaying structures. |
| Describe the Anatomical Position | - Standing upright - Head and eyes directed straight ahead - Upper limbs at the sides - Upper limbs slightly sway from trunk - Palm facing forward - thumbs pointing away from body - Lower limbs parallel - Feet flat on the ground and facing forward |
| What is the difference between supine and prone? And what is their applications in radiographic positioning? | Supine is lying face up. Prone is lying face down. In radiographic positioning, supine is often used for general imaging of the abdomen and chest, while prone positioning can be beneficial for visualizing specific areas like the spine. |
| What is Caudal and Cephalic anatomical direction and their applications in radiographic positioning? | Caudal refers to the direction towards the tail (or feet in humans), while Cephalic means towards the head. In radiographic positioning, these terms are used to describe the angle of the X-ray beam. |
| What is Proximal and Distal anatomical direction and their applications in radiographic positioning? | Proximal refers to a point closer to the center of the body, while Distal refers to a point further away from the body's center. In radiographic positioning, these terms are used to describe the location of structures based on whether a part is closer to |
| List and describe the two Classifications of the Human Skeleton. | 1- the axial skeleton: It forms the central axis of the body, including the skull, spine, and ribcage. 2- the appendicular skeleton: It consists of the limb's bones (arms and legs) along with the shoulder and pelvic girdles. |
| Recognize and explain the body position. | Trendelenburg. |
| Recognize and explain the body position: Supine, heads up 15 degrees. | Reverse Trendelenburg. |
| Recognize and explain the body position: Patient is lying face up. | Supine. |
| Recognize and explain the body position: Patient is laying down | Recumbent. |
| Identify the Planes of the Body. | - Coronal Plane: Separates into Anterior/Posterior (front/back) - Midsagittal/ Sagittal Plane: Separates into Right and Left portions. Divides the body vertically. - Transverse Plane: Divide the body straight across in Superior and Inferior. Divides the |
| Identify the importance of the Planes of the Body in radiography. | These planes are crucial in radiography as they allow medical professionals to accurately position patients and interpret images by providing a standardized way to visualize internal structures from different angles. |
| Explain the use of Positioning Landmarks for proper alignment during imaging. | Positioning landmarks are identifiable anatomical features on the body that radiographers use during imaging procedures, ensuring the target area is correctly positioned in relation to the X-ray beam, leading to clear and accurate diagnostic images by min |
| Provide examples of Position Landmark: | Skull: The external occipital protuberance, mastoid process, orbital rims Spine: Spinous processes, iliac crests Chest: Midsternal line, nipple line, clavicle Abdomen: Umbilicus, anterior superior iliac spines Extremities: Epicondyles, condyles, malle |
| Describe Routine Positions for Upper Extremities and their importance in diagnostic imaging. | It includes: Anteroposterior (AP) and lateral views of the shoulder, humerus, elbow, forearm, wrist, and hand. key positions include slight abduction of the arm for shoulder AP views, full extension of the elbow for lateral views, and proper hand positio |
| Discuss how kVp Adjustments are made for different imaging needs | kVp control s the penetrating ability of the beam so if the patient has a cast or have a larger body mass, the radiographer must make manual adjustments to increase the amount kVp to make sure the x-ray is able to pass through the cast and the patient's b |
| Explain the purpose of Automatic Exposure Control (AEC) and its role in patient safety. | AEC feature automatically adjusts the radiation exposure delivered to a patient during an imaging procedure, ensuring a consistent image quality while minimizing unnecessary radiation dose. It plays an important role in the patient safety by preventing o |
| Discuss when and why Grids are used in radiography. | Grid is a device use to absorb scatter radiation, they function to improve subject contrast. Primarily used when imaging thicker body parts, like the abdomen or pelvis. |
| Identify the Components of the X-ray System | - X-ray tube and support system: Anode and Cathode - Collimator Assembly: located riught below the tube. - X-ray Table - X-ray generator - Control Console: Electronic cabinet and Operator console. - Upright IR holding device: Wall mounted cassette an |
| Differentiate between types of X-ray Tables and Support Systems. | The table is the platform where the patient lies (stationaty or mobile), while the support system helps position them correctly for imaging (can vary depending on the patient positioning needs, including adjustable sections, padded surfaces, and specializ |
| Explain how to properly center the CR for Hand and Wrist Imaging. | The Central ray must be perpendicular from the hand and wrist. |
| Define terms for Body Movements, such as supination and pronation. | These terms are used to describe the orientation of the hand, arm, or foot. Supination: the rotation of the forearm and hand so that the palm faces up Pronation: the rotation of the forearm and hand so that the palm faces down |
| Define terms for Body Movements, such as eversion and Inversion. | These terms are used to describe the movement of the foot in relation to midline of the body. Eversion: The movement of the sole of the foot away from the midline of the body Inversion: The movement of the sole of the foot toward the midline of the bod |
| Define terms for Body Movements, such as Dorsiflexion and Plantar flexion. | These terms are used to describe the movement of the foot decreasing the angle between two structures: Dorsiflexion: The movement of the top of the foot toward the leg, toes lifted towaerds the shin. Plantar flexion: The movement of lifting the heel an |
| Describe the Importance of Image Orientation (e.g., long axis of the part aligned with the image receptor). | To ensure that the part being imaged is fully captured within the boundaries of the image receptor, this will maximize the quality and informational value of the image. |
