Stack #3061750
| Question | Answer |
|---|---|
| Source of x-rays | X-ray tube |
| X-ray tube is surrounded by a lead-lined | Tube housing |
| X-rays that are created exit the tube housing through an opening called the | Tube port |
| Radiation that leaves the tube is called | Primary radiation |
| The squared area of the X-ray beam that strikes a patient and x-ray table is | Radiation field |
| An imaginary line in the center of the X-ray beam and perpendicular to the long axis of the X-ray | Central Ray |
| Journey x-ray exposure x-rays from the tube are directed through the patient | Image receptor |
| Anatomic structures that have greater tissue density such as bone | Will absorb more radiation than less dense tissue such as muscle |
| Radiation that exits on the opposite side of the patient is called | Remnant radiation or exit radiation |
| The image receptor or IR that contains the unseen image is called a | Latent image |
| Absorption of the X-ray beam is called | Attenuation |
| What is the primary source of scattered radiation | The patient |
| X-ray photons leaving the X-ray tube before they interact with matter | Primary radiation |
| X-ray photons that interact with matter and scatters in | Scattered radiation |
| X-ray photons that reach the | Remnant radiation makes the image |
| X-rays and visible light properties | Travel in straight lines affect photographic emulsions cause harmful biological effects |
| X-rays | 1 Cannot be detected by human senses 2 can penetrate matter 3 can cause certain materials to to fluoresce |
| Boxlight device attached under tube housing allows operator to vary size of radiation field | Collimator |
| Primary radiation | X-ray photons leaving the X-ray tube before they interact with matter |
| Scatter radiation | X-ray photons that interact with matter and scatter in many directions |
| Remnant radiation | X-ray photons that reach the image receptor remnant makes the image |
| X-rays consist of | Electromagnetic energy |
| X-rays have a shorter | Wavelength and are more penetrating |
| Electromagnetic energy properties | Light x-rays radio waves microwaves |
| Which kvp will will result in the most penetration 60 kvp or 80 kvp | 80 kvp |
| Most frequent adverse incident in x-ray room | Patient falling |
| AEC | Auto exposure control or phototiming |
| Primary radiation | X-ray photon leaving tube before interaction with matter |
| Scattered radiation | X-ray photons interacting with matter scatters in many directions |
| Remnant radiation | X-ray photons reach image receptor |
| Image receptor defined | Device changes x-ray beam into visible image |
| Sponges are | Radiolucent Does not absorb x-rays |
| Pattern radiation creates image on film | Remnant |
