they are....
✔✔-initial set up cost
-Image quality (when used alot)
-sensor size
-infection control
-legal issues - ✔✔What are the disadvantages of digital imaging? (5)
✔✔Thicker and less flexible - ✔✔Most digital x-ray sensors are
__________________________ than intraoral film. (Size)
✔✔heat sterilization - ✔✔Digital sensors cannot withstand what type of sterilization?
✔✔Evidence in court - ✔✔Because the original digital image can be enhanced, it is
questionable whether it can be used as...
✔✔ No film is used - ✔✔What kind of film is used in digital radiography?
✔✔No - ✔✔Are radiographic solutions used in digital radiography?
✔✔Electronic sensor - ✔✔Digital radiography uses an
________________________________ and a computerized imaging system that
produces x-ray images almost instantly on a computer monitor
✔✔Sensor - ✔✔A small wired or wireless electronic square or rectangle used to capture
ray images
✔✔seconds - ✔✔How long does it take for the sensor to transmit the information on the
computer to display the image?
✔✔Analog image - ✔✔radiographic image produced by conventional film
✔✔analog to digital converter - ✔✔method used to convert data elements acquired by
the sensor are communicated to the computer in analog form and then converted into
digital form
✔✔Bit-depth image - ✔✔number of possible gray-scale combinations for each pixel
, ✔✔charge-coupled device (CCD) - ✔✔solid-state silicon chip detector that converts light
or x-ray photons into an electrical charge or signal; in digital imaging, is found in the
sensor
✔✔Digital Imaging - ✔✔Filmless imaging system; a method of capturing an image using
a sensor, breaking it into electronic pieces, and presenting and storing the image using
a computer and related imaging software.
✔✔Digital Image - ✔✔an image composed of pixels that can be stored in a computer
✔✔Digital subtraction - ✔✔One feature of digital imaging; a method of reversing the
gray scale as an image is viewed; radiolucent images (normally black) appear white,
and radiopaque images (normally white) appear black.
✔✔Digitize - ✔✔In digital imaging, to convert an image into a digital form that, in turn,
can be processed by a computer
✔✔Direct digital imaging - ✔✔Method of obtaining a digital image, in which an intraoral
sensor is exposed to x-radiation to capture a radiographic image that can be viewed on
a computer monitor
✔✔Indirect digital imaging - ✔✔Method of obtaining a digital image, in which a sensor is
scanned after exposure to x-radiation and then converted into a digital form that can be
viewed on a computer monitor.
✔✔line pairs per millimeter (lp/mm) - ✔✔measurement used to evaluate the ability of
the computer to capture the resolution of an image
✔✔Pixel - ✔✔A discrete unit of information. In digital electronic images, digital
information is contained in, and presented as, discrete units of information; also termed
picture element.
✔✔Sensor - ✔✔In digital imaging, a receptor that is used to capture an intraoral or
extraoral image
✔✔Storage phosphor imaging - ✔✔Method of obtaining a digital image in which the
image is recorded on phosphor-coated plates and then placed into an electronic
processor, where a laser scans the plate and produces an image on a computer screen.
✔✔To generate images that can be used in diagnosis and assessment of dental
disease - ✔✔What is the purpose and use of digital imaging?
✔✔Similar - ✔✔Digital images present _____________ information as a film based
radiograph, just a lot faster.
