Fig– Difference between an X-ray projection (B) and a CT slice (C) of an imaged object (A). Conventional radiography involves the use of x-rays; the term “plain x-rays” is sometimes used to distinguish x-rays used alone from x-rays combined with other techniques (eg, CT) This chapter explains the principle of projection X-ray imaging, also called “conventional X-ray imaging”. Expand PDF The reasons are that radiographs are very useful indifferentiating RA from other clin-ical entities, and that radiographs have high spec-ificity, provide a quick overview of all symptomatic joints, and are low-cost procedures. Unfortu-nately, the interpretation of conventional radiology can be considered a vanishing art. In the following article, options for radiologists and physicists to Comparison of radiation doses to patients undergoing standard radiographic examinations with conventional screen–film radiography, computed radiography and direct digital radiography. This contribution will discuss the role of conventional radiography and the part played by contrast agents in enhancing diagnostic yield Most modern CR (computed radiography) and DR systems now effectively offer compared to screen-film (analog) radiography. Different ing treatment. In particular, it is the mainstay of initial evaluation of the hands, wrists, feet, and sacroiliac (SI) joints An understanding of the basic principles of plain film radiography, its limitations and the precautions necessary to reduce exposure to ionizing radiation are essential to ensure maximum diagnostic benefit. In this review, the development of digital radiography is presented with a description of its various forms and a comparison with screen film radiography Conventional radiography, where electromagnetic radiation at a certain wavelength passes a body and creates a two-dimensional image on film or a digital detector depending on the amount of X-rays absorbed on its way, has been the mainstay of radiology since This chapter explains the principle of projection X-ray imaging, also called “conventional X-ray imaging”.

For conventional radiography, an x-ray beam is generated and passed through a patient to a piece of film or a radiation detector, producing an image.
