Final Study Stack
| Question | Answer |
|---|---|
| Diagnostic Yield | the amount of useful diagnostic information obtained from an image after the exposure |
| Diagnostic Efficiency | measures the accuracy of the diagnostic information |
| Components of the X-Ray System | X-ray tube, generator, control operating console |
| What is an upright image receptor used for? | For patients who are standing or erect position - used mostly for chest and abdominal x-rays |
| Different types of Receptors | Film-screen (analog), Computed Radiography ( CR), Digital Radiography (DR) |
| Name some Anatomical Terms | Caudal-towards the feet, Cephalic-toward the head, proximal-closer to the point/trunk, distal-further from the point/trunk |
| Planes of the Body | Sagittal- right/left portions, Midsagittal- equal right/left halves, Coronal/Frontal- anterior/posterior, Tranverse-superior/inferior |
| Describe bodily structures in relation to one another | Ex. the radius is more proximal to the body than the ulna, the ankle is more caudal than the wrist |
| Terms for body movements | Dorsiflexion-toes upward, Plantar flexion-toes downward, Rotation- turning around axis |
| Explain the purpose of the collimation assembly and its importance in radiation protection. | To prevent over exposure, reduce radiation scatter, improves contrast |
| Recognize the different positioning aides | Wedges, sandbags, and tape |
| Differentiate between the types of x-ray tube support systems | Ceiling-mounted tube support: moves along the ceiling tracks, C-arm: used in surgery & fluoroscopy, U-arm system: tube&receptor move together |
| Types of X-ray Tables | Fixed table: stationary, routine exams, Floating table: moves multiple directions, Elevating table: adjust to height |
| Identify qualities needed to be a caring radiologic and imaging sciences professional. | Compassion, emotional intelligence, critical thinking skills |
| Recognize specialty radiology suites | A few suites: Computed Tomography (CT)- takes real-life cross-sectional images of the body, Magnetic Resonance Imaging (MRI) - is a non-ionizing suite, uses a large magnet and radio waves to created images inside of the body |
