LESSON 6: Digital Imaging, Dental Film and Processing Radiographs

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. DARK AREA ON FILM

2. FILM EXPOSURE TO LIGHT BEFORE BEING PLACED IN PROCESSING SOLUTION

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. FINGERPRINTS

2. HANDLING FILMS BY ITS EDGES UNTIL PROCESSING IS COMPLETE

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. SCRATCHED FILM

2. DEVELOPER SOFTEN THE EMULSION, LEAVING IT SCRATCHED AND CAREFUL HANDLING, ESPECIALLY BEFORE FIXING, WILL PREVENT SCRATCHES

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. STATIC ELECTRICITY

2. REMOVING FILM TO QUICKLY FROM PACKET

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. CLEAR FILM

2. ACCIDENTALLY POURING FIXER INTO DEVELOPER TANK AND DEVELOPER INTO FIXER TANK. FILMS PASS THROUGH THE FIXER FIRST, THEN DEVELOP. TURNS CLEAR

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. WHITE FIXER SPOTS

2. FILM SPLASHED WITH FIXER BEFORE PRECESSING (DEVELOPER)

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. DEVELOPER CUT OFF

2. NOT ENOUGH DEVELOPER IN THE TANK. SOLUTION ONLY COVERS HALF THE FILM. RESULTS IN A STRAIGHT WHITE BORDER

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. ROLLER MARKS

2. FROM DIRTY ROLLERS ON AUTOMATIC PROCESSORS

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. FIXER CUT-OFF

2. NOT ENOUGH FIXER IN TANK. SOLUTION ONLY COVERS HALF OF THE FILM. RESULTS IN A STRAIGHT BLACK BORDER

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. 2 OVERLAPPING FILMS

2. FILMS STUCK TOGETHER DURING PROCESSING

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. OVERDEVELOPED FILM

2. DEVELOPING SOLUTION IS NORMALLY 81-83 DEGREES FERINHET. IF IT GETS TO HOT, FILM WILL LOOK DARK OR BLACK

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. RETICULATION

2. SUDDEN TEMPERATURE CHANGE BETWEEN DEVELOPER AND WATER BATH WILL RESULT IN ETICULATION OF THE FILM EMULSION

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. EXHAUSTED DEVELOPER

2. THE DEVELOPER SOLUTION IS TO WEAK RESULTING IN THE FILM TO BE LIGHTER THAN NORMAL

THE PROCESSING ERROR DEPICTED IN THE PICTURE CAN BE DESCRIBED AS WHAT? THE CAUSE WAS DUE TO:

1. BROWN STAIN ON FILM

2. FIXER SOLUTION TOO OLD, CHEMICALS EXHAUSTED OR INADEQUATE WASHING WITH WATER

WHICH OF THE FOLLOWING FACTORS WILL AFFECT THE LIFE OF THE PROCESSING SOLUTIONS

1. NUMBER OF FILMS PROCESSED

2. TIME ELAPSED SINCE LAST CHANGE

3. SIZE OF FILMS PROCESSED

DIGITAL IMAGES ARE NOT RADIOGRAPHS, THEY ARE:

1. ELECTRONIC SIGNALS

2. CAPTURED BY SENSORS

3. DISPLAYED ON A MONITOR

4. CAN BE PRINTED

5. EMAILED TO INSURANCE COMPANIES OR OTHER DENTIST

WHAT ARE THE 2 BASIC METHODS OF ACQUIRING DIGITAL X-RAY IMAGES?

1. DIRECT IMAGING

2. IN DIRECT IMAGING

IN DIRECT IMAGING, THE CCD (CHARGED COUPLED DEVICE) FOUND IN DIRECT DIGITAL IMAGING SENORS IS MADE OF WHAT?

SILICON

BARRIERS ARE USED ON CCD’S (CHARGED COUPLED DEVICE) AND PSP’S (PHOSPHOR STORAGE PLATE) BECAUSE DIGITAL SENSORS ARE NOT WHAT?

1. DISPOSABLE

2. AUTOCLAVE ABLE

Digitizing film-based radiographs is similar to placing film on a duplicator light box. This type of indirect imaging is slightly less ___ than __.

1. DETAILED

2. DIRECT IMAGING
