Radiography Quiz


Radiography QuizVersion en ligne Test your radiography knowledge par Sharif Mamarasulov 1 What is the primary purpose of radiography in medicine? a To replace MRI for soft tissue imaging b To create images of internal body structures using X-rays c To treat all illnesses with radiation d To measure patient weight using photons 2 Which unit is commonly used to measure the exposure ofX-ray beams? a Liters (L) b Exposure measured in air KERMA (Gy) c Celsius (°C) d Decibels (dB) 3 Which material is most effective at absorbing X-rays? a Glass b Plastic c Lead d Aluminum 4 What is the purpose of a radiographic grid? a To measure patient height b To reduce scattered radiation and improve image contrast c To focus the image to the detector d To cool the X-ray tube 5 Which safety principle is crucial in radiography? a ALARA (As Low As Reasonably Achievable) b FAST (Frequency As Safe Transport) c BRIGHT (Balanced Radiation Is Great Here) d NOISE (Never Overexpose In Scans Exact) 6 Which type of detector is commonly used in digital radiography? a Gas-filled chamber b Flat-panel detector c Photomultiplier tube d Photographic film 7 What effect does increasing kVp have on X-ray quality? a Increases beam penetrability and reduces image contrast b Reduces beam energy c Sharpens soft tissue detail without tradeoffs d Decreases patient dose without affecting image 8 Which positioning error can cause magnification of a structure? a Patient movement during exposure b Incorrect grid alignment c Excessive exposure time d Object too far from the image receptor 9 Which term describes a radiograph where the patient is rotated or not aligned correctly? a A PA view b A lateral view c An oblique view d A flexion view 10 What is the function of radiographic contrast agents? a To cool the imaging receptor during exposure b To enhance visibility of specific structures or vessels c To speed up image acquisition d To protect patient from radiation Feedback 1 Radiography uses X-rays to visualize internal structures; it does not treat, weigh, or fully replace MRI for soft tissues. 2 KERMA (Gy) is the exposure in air; other units listed are not used to measure X-ray beam exposure. 3 Lead has high atomic number and density, providing excellent X-ray attenuation compared to aluminum, plastic, or glass. 4 Grids reduce scatter, enhancing image contrast; they do not cool tubes, focus images, or measure height. 5 ALARA is the standard safety principle to minimize exposure; other options are not real guidelines. 6 Flat-panel detectors are standard in digital radiography; traditional film and gas chambers are not typical in modern digital systems. 7 Higher kVp increases penetrability and often lowers contrast; dose may increase or decrease depending on technique. 8 If the object is far from the receptor, geometric magnification increases; other errors affect sharpness or dose. 9 An oblique view results from rotation; PA and lateral are standard orientations, flexion is a position term. 10 Contrast agents improve delineation of anatomy or vessels; they do not speed, protect from radiation, or cool receptors.
