A developer is a chemical solution that changes the film latent image to a visible image composed of black metallic silver.

(DICOM) DICOM is the industry standard for transferral of radiologic images and other medical information between computers. Patterned after the Open System Interconnection of the International Standards Organization, DICOM enables digital communication between diagnostic and therapeutic equipment and systems from various manufacturers.
The DICOM 3.0 standard evolved from versions 1.0 (1985) and 2.0 (1988) of a standard developed by the American College of Radiology (ACR) and National Electrical Manufacturers Association (NEMA). To support the implementation and demonstration of DICOM 3.0, the RSNA Electronic Communications Committee began to work with the ACR-NEMA MedPacs ad hoc section in 1992.
Also Picture Archiving and Communication Systems (PACS), which are connected with the Radiology Information System (RIS), use commonly the DICOM standard for the transfer and storage of medical images.

A film processor is a peripheral x-ray equipment used in conjunction with a camera to create hard-copy images. Film processors should be maintained at their optimum operating conditions by regular quality control procedures. Optimal film processing has important implications for the diagnostic quality of the image stored on film.

Different filter types are used in medical imaging to improve image quality.
Filter materials such as aluminum, iron or copper, located in the primary x-ray beam between tube and collimator, filter out lower energetic x-rays (for example bow-tie filter). Filters partially absorb or attenuate the x-ray beam to prevent radiation overexposure. The sum of filtration consists of inherent and added filters. This filtration affects the beam energy and ability to penetrate materials.
Mathematical filter procedures are used for the convolution of the attenuation profiles and reconstruction of computed tomography (CT) images.

The latitude is the range between the minimum and maximum x-ray exposure to an image receptor that yields a diagnostic image of structures.
