Radiocontrast agent

radiocontrastcontrastcontrast agent
Plain radiography can also refer to radiography without a radiocontrast agent or radiography that generates single static images, as contrasted to fluoroscopy, which are technically also projectional.
Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray-based imaging techniques such as computed tomography (contrast CT), projectional radiography, and fluoroscopy.

Medical imaging

imagingdiagnostic imagingdiagnostic radiology
Projectional radiography is a form of radiography and medical imaging that produces two-dimensional images by x-ray radiation.
In the case of projectional radiography, the probe uses X-ray radiation, which is absorbed at different rates by different tissue types such as bone, muscle, and fat.

Photostimulated luminescence

computed radiographyimage platePhotostimulable Phosphor Plate
Detectors can be divided into two major categories: imaging detectors (such as photographic plates and X-ray film (photographic film), now mostly replaced by various digitizing devices like image plates or flat panel detectors) and dose measurement devices (such as ionization chambers, Geiger counters, and dosimeters used to measure the local radiation exposure, dose, and/or dose rate, for example, for verifying that radiation protection equipment and procedures are effective on an ongoing basis).
A plate based on this mechanism is called a photostimulable phosphor (PSP) plate and is one type of X-ray detector used in projectional radiography.

Detectors can be divided into two major categories: imaging detectors (such as photographic plates and X-ray film (photographic film), now mostly replaced by various digitizing devices like image plates or flat panel detectors) and dose measurement devices (such as ionization chambers, Geiger counters, and dosimeters used to measure the local radiation exposure, dose, and/or dose rate, for example, for verifying that radiation protection equipment and procedures are effective on an ongoing basis).
They are used in both projectional radiography and as an alternative to x-ray image intensifiers (IIs) in fluoroscopy equipment.

Radiography

Plain radiography can also refer to radiography without a radiocontrast agent or radiography that generates single static images, as contrasted to fluoroscopy, which are technically also projectional. Projectional radiography is a form of radiography and medical imaging that produces two-dimensional images by x-ray radiation.
The generation of flat two dimensional images by this technique is called projectional radiography.

Chest radiograph

On lumbar and chest radiographs, it is anticipated that ERMF is between 1.05 and 1.40.
A chest radiograph, called a chest X-ray (CXR), or chest film, is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures.

CT scan

Plain radiography generally refers to projectional radiography (without the use of more advanced techniques such as computed tomography that can generate 3D-images).

Abdominal x-ray

kidneys, ureters, and bladderkidneys, ureters, and bladder x-rayKUB
In children, abdominal radiography is indicated in the acute setting in suspected bowel obstruction, gastrointestinal perforation, foreign body in the alimentary tract, suspected abdominal mass and intussusception (latter as part of the differential diagnosis).
An abdominal x-ray is an x-ray of the abdomen.

Projectional radiography is the practice of producing two-dimensional images using x-ray radiation.

Gastrointestinal perforation

In children, abdominal radiography is indicated in the acute setting in suspected bowel obstruction, gastrointestinal perforation, foreign body in the alimentary tract, suspected abdominal mass and intussusception (latter as part of the differential diagnosis).
A CT scan is typically the preferred method of diagnosis; however, free air from a perforation can often be seen on plain X-ray.

Tomography

In many cases, the production of these images is based on the mathematical procedure tomographic reconstruction, such as X-ray computed tomography technically being produced from multiple projectional radiographs.

Focal plane tomography

This is a panoramic imaging technique of the upper and lower jaw using focal plane tomography, where the X-ray generator and X-ray detector are simultaneously moved so as to keep a consistent exposure of only the plane of interest during image acquisition.
Focal plane tomography’s development began in the 1930s by the Italian radiologist Alessandro Vallebona as a means of reducing the problem of superimposition of structures which is inherent to projectional radiography.

Rickets

For example, skeletal signs of rickets are seen predominantly at sites of rapid growth, including the proximal humerus, distal radius, distal femur and both the proximal and the distal tibia.

Visual artifact

Disease mimics are visual artifacts, normal anatomic structures or harmless variants that may simulate diseases or abnormalities.
In projectional radiography, visual artifacts that can constitute disease mimics include jewelry, clothes and skin folds.

Projectional radiographs generally use X-rays created by X-ray generators, which generate X-rays from X-ray tubes.

A Bucky-Potter grid may be placed between the patient and the detector to reduce the quantity of scattered x-rays that reach the detector.
