| Question | Answer |
|---|---|
| What is the principle of diagnostic yield? | Diagnostic yield is the amount of useful diagnostic information obtained from an image. The goal is to produce an image that provides enough information for an accurate diagnosis. |
| What is the principle of diagnostic efficiency? | Diagnostic efficiency means producing the necessary diagnostic information while using the appropriate amount of radiation, time, and resources. |
| What does manipulating radiographic equipment involve? | It involves adjusting the equipment, tube, table, image receptor, and other controls to properly position the patient and obtain the required image. |
| What are the basic components of an x-ray system? | The main components include the x-ray tube, control console, generator, tube support, image receptor, and patient table/upright receptor stand. |
| What are the major controls on the radiographic control console? | The major controls include kVp, mA, exposure time, and the exposure switch. These controls determine how the x-ray exposure is produced. |
| Why are exposure controls important to a radiologic technologist? | Exposure controls allow the technologist to adjust the x-ray exposure to produce a diagnostic image while avoiding unnecessary radiation to the patient. |
| What is the purpose of collimation? | Collimation limits the size and shape of the x-ray beam. It helps reduce unnecessary radiation exposure and reduces scatter radiation, which can improve image quality. |
| What are different types of x-ray tables? | X-ray tables can differ by their design and movement. Some tables are fixed, tilting, or floating, allowing different positioning options depending on the examination. |
| What are the different types of x-ray tube support systems? | Tube support systems hold and allow movement of the x-ray tube. Common types include floor-to-ceiling supports, ceiling-mounted systems, and floor-mounted systems. |
| What is the purpose of an upright image receptor? | An upright image receptor allows the technologist to take radiographs with the patient standing or sitting. It is commonly used for exams such as chest and upright abdominal images. |
| What are the different types of image receptors? | Image receptors include computed radiography (CR) and digital radiography (DR) systems. CR uses an imaging plate that must be processed, while DR captures the image electronically. |
| What are positioning aids used for? | Positioning aids help keep the patient or body part in the correct position during an examination. Examples include sponges, sandbags, straps, and other supports. |
| What are specialty radiology suites? | Specialty suites are rooms designed for specific types of imaging or procedures. Examples include fluoroscopy, mammography, CT, MRI, and interventional radiology suites. |
| What are the three main planes of the body? | Sagittal: divides the body into right and left portions. Coronal: divides the body into anterior and posterior portions. Transverse: divides the body into superior and inferior portions. |
| why patient interaction is important to patients, as well as their family and friends. | Patient interaction is important because it helps patients and their loved ones feel comfortable, respected, informed, and less anxious during healthcare. |
