Let me process what happened.
This matrix type will create smaller pixels and improve sharpness
Larger matrix
This type of equipment relies on excellent positioning skills and extensive knowledge of surface and internal anatomy because the part being radiographed must be accurately positioned over the ionization sensors.
Automatic Exposure Control (AEC)
As you increase OID, this happens to contrast
Contrast increases
This type of grid contains lead strips that are parallel to one another and the x -ray tube may be angled along the length of the grid without cutoff.
Linear Grid
This is the amount in inches that the secondary barrier should be in an x ray room.
1/32 in
This is the universal protocol for transmitting data in PACS and contains the patient's name, DOB, and type of study.
DICOM.
This type of equipment is also known as the variable transformer, its the source for selecting kVp, and provides for the variation of voltage flowing in the x-ray circuit and applied to the x-ray tube.
Autotransformer
This will create few gray tones, mainly a black and white image. This may also be referred to as short-scale contrast.
High Contrast
This refers to the darkening of images by sources other than the radiation of the transmitted beam
Fog
This is the minimum requirement of lead used for an apron when being exposed to radiation.
0.25mm of lead equivalent
This is an image processing filter that enhances the contrast around distinct structures on an image in an attempt to improve its apparent sharpness.
Edge enhancement
The target of the x ray tube is made of this material
Tungsten
In radiology this refers to the ability of the imaging modality to distinguish between small structures that are very close together.
Spatial resolution
This has been used in digital radiography to provide feedback to the technologist regarding the proper radiographic techniques for a specific exam that achieves an optimal image
Exposure Index.
This is a device that is attached to the opening of the x-ray tube housing to regulate the size and shape of an x-ray beam.
Variable aperture/collimator/beam restrictor
This is the process of combining multiple radiographic images with overlapping fields of view to produce a segmented panorama
Stitching
In this type of radiography the image receptor is an imaging plate made of photostimulable phosphors that is placed in a reader unit which removes the IP so that is may be scanned by a laser
Computed Radiography (CR).
This is the difference in absorption based on the shape or makeup of the tissue being imaged
Differential absorption/subject contrast
Degrade image quality and have been produced by hardware failure, operator error and software errors (post-processing)
Image Artifacts
This is a plan of action to ensure that a diagnostic x-ray facility will produce consistent, high-quality images with a minimum of exposure to patients and personnel.
Quality Assurance
This is a graphical display of the pixel intensity distribution for a digital image.
Histogram.
This equipment is used to convert low energy radiation into visible light images in fluoroscopy.
Image Intensifier.
Higher energy x-ray beams have fewer _____ interactions than x-ray beams with lower energy
Photoelectric
This is caused by too few x-ray photons hitting the image receptor. It is a source of noise in the image.
Quantum mottle
Improper alignment of this will result in shape distortion.
Central ray, IR, and part.
