Quality Control Procedures

Running a QC Baseline	Per the MQSA, a baseline test must be run when the 8900 is first installed
Test	and must be repeated every time a box of film with a different emulsion
	number is used. This test sets up a baseline set of film parameter values
	that shall be used as a standard for comparison in daily quality control
	tests. Kodak recommends the procedure described below as a means of
	complying with this regulation.
Procedure for the	The installing field engineer verifies that the 8900 meets its performance

	image of the site's choice. The site's responsible healthcare professional is
	asked to approve that the 8900 produces an acceptable clinical image. If
	the image is not acceptable, the field engineer repeats his procedures until
	the settings for the baseline print produce acceptable clinical images.
Procedure for the QC	After an acceptable installation, the user facility's technologist must repeat
Technologist	the baseline test whenever a change occurs in film lot number.
	NOTE: The following is an example of a film lot number:
	020662-0211-A-019. The film emulsion number is underlined.
Baseline Test	1. Apply power to the 8900 and allow it to warm to READY, as indicated
	on the local panel. Request a Calibration Test Print (see “Requesting a
	Calibration Test Print” on page 3-19) to put its Automatic Image
	Quality Control (AIQC) system in control.
	2. Print two QC Step Wedge test films (see “Requesting a QC Step
	Wedge” on page 3-20). See the figure on the next page for a sample
	step wedge.
	3. Using a densitometer, read and record the density of each step (1
	through 21) on each of the two test films. (For consistency from film
	to film, always read density at the center of each wedge.) The QC Step
	Wedge is positioned on the film to allow for the use of an automatic
	densitometer such as the X-RiteModel 391 Densitometer for
	automatic density recordings.
	NOTE: You can choose to use a clear area on the test films instead of the
	actual step 1 area to take the “step 1” density reading.
	4. Determine and record the average of the two densities read for each
	step.
	5. Select from the average values calculated from the 21 steps to
