Projectional radiography is also known as plain film radiography that means the practice of producing the x-ray images in a 2-dimensional way. Generally, some of your body parts that are being x-rayed are taken in 2 projections at right angles to one another. The projection is taken in two ways for 2 main reasons. Firstly, some of the fractures are seen only in one direction and the accurate direction may not be known to the radiographer unless the image is taken in different angles. The second reason is for assessing the alignment of the fractures as well as spatial position of the foreign body present inside your body.

Projectional radiography is generally used for the detection of arthritis, dislocations, fractures, scoliosis, benign, malignant tumors and some of the bone conditions like osteomyelitis and scleroderma. It is also used to detect the anomalies of the soft tissues of the body such as bowel perforations, chest pathology, foreign body and acute bowel obstruction.

The different equipments that are used for the Projectional radiography include user interface, ceiling or the floor mounted x-ray tube, digital detector, height adjustable table, image receptor- like film or screen cassettes, DR detectors or CR plate, chest stand and a image reader or the processor.

Projectional radiography creates quality images when the object is exposed to the x-rays or other high forms of energy like the electromagnetic radiation and then the resulting remnant shadow is captured as a latent image. This shadow can be transferred to light with the use of a fluorescent screen that will be later on captured on a photographic film. Some of the organs of your body like the lungs, bones particularly lend themselves to the projection radiography. Projectional radiography is an inexpensive technique giving you high yield of diagnosis.

Limitations of Projectional radiography: there are few limitations associated with the Projectional radiography. The 2-D images lay over the non-adjacent tissues, hence diminishing the inter-relationship of the breast tissues. The 3D arrangement of the breast tissues cannot be cannot be completely presented by the 2D images, thus resulting in the loss of information of the morphologic images.
