DIGITAL IMAGE LATEST EXAM 2026/2027 QUESTIONS
AND SOLUTIONS RATED A+
✔✔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.
✔✔Image - ✔✔What is the term used to describe the pictures that are produced through
digital imaging?
✔✔Digitized - ✔✔The sensor is placed inside the mouth; an electronic charge is
produced on the surface of the sensor this electronic signal is _______________
✔✔Computer - ✔✔Following digitization, the sensor transmits this information to a
________________________ where the incoming electronic signal is stored
✔✔More - ✔✔The typical sensor is ___________ sensitive to x-rays than conventional
film
✔✔50-80% - ✔✔Because a sensor is more sensitive to x-rays, the exposure times are
___________________ less then that required for conventional radiography using E
speed film
✔✔YES - ✔✔Since there is less X radiation use with digital imaging, does the patient
still need to wear a lead apron?
✔✔- X-radiation source
- intraoral sensor
- computer - ✔✔What are the three pieces of equipment used during digital
radiography?
✔✔-charge coupled device
-complementary metal oxide semiconductor/active pixel sensor
-charge injection device - ✔✔What are the three types of intraoral sensors that can be
used? (Directly connected to the computer)
, ✔✔Conventional dental x-ray unit - ✔✔Most digital imaging systems use a
__________________________________________ as the x radiation source
✔✔1/100 of a second - ✔✔The conventional dental x-ray unit timer must be adapted to
allow exposures in a timeframe of
✔✔True - ✔✔(T/F) A Standard x-ray unit that is adapted for digital imaging can still be
functional for conventional radiography.
✔✔intraoral sensor - ✔✔A small detector that is placed in the mouth of the patient and
used to capture the radiographic image
✔✔wired or wireless - ✔✔Intraoral sensors can be...
✔✔Wired intraoral sensor - ✔✔The image sensor is linked by fiber optic cable to a
computer
✔✔Wireless intraoral sensor - ✔✔The imaging sensor is not linked by a cable
✔✔0, 1, 2, and 4 - ✔✔Most manufacturers produce sensors similar in dimension to size
______________________ intraoral films
✔✔-charge coupled device
-complementary metal oxide semi conductor/active pixel sensor - ✔✔Name the two
most popular types of direct sensor technologies.
✔✔charge-coupled device (CCD) - ✔✔The most common image receptor used in dental
digital imaging
✔✔Pixels - ✔✔The CCD produces an image that is composed of _____________ that
can be stored in a computer
✔✔Fax machines, home video cameras, microscopes, and telescopes - ✔✔CCD
Technology is also used in...
✔✔Silicon chip - ✔✔The __________________ in a CCD, is what is sensitive to x-rays
or light
✔✔Silver crystal - ✔✔A pixel is the digital equivalent of a
__________________________ in conventional radiography
