automatically sets programmed X-ray techniques and exposure factors,
including AEC mode (if available), bucky selection, kVp, mA, time, initial
anatomical thickness, and AEC density. Pre-programmed APR settings can
be modified at any time through the operator control panel, either in the
actual stored program or for the current exam (i.e., temporarily). During
exposure, AEC (optional) works in conjunction with APR to provide uniform,
repeatable, high-quality images with the smallest variation of optical density
between patients. Additionally, a "Patient Type" sub-mode is provided for
APR selections that are configured for manual exposure control (i.e., non-
AEC). When this sub-mode is accessed, the patient type is initially set for
average (i.e., typical "cm") setting. The PATIENT TYPE up/down keys
provide quick time/mAs compensation (±25% and ±50% settings) in
accordance with physical characteristics of patient (i.e., muscular, thin,
heavy, etc.), or exposure parameters are adjusted by selecting cm or setting
individual exposure factors.
NOTE: On systems equipped with AEC option, all
techniques may be toggled between AEC and non-
AEC modes using the AEC mode button.
• AEC MODE: Automatic Exposure Control (optional) uses an ion chamber to
ensure proper optical density with compensation for programmable film/
screen speeds. (If AEC option is not installed, AEC mode is inaccessible to
operator.)
• MANUAL MODE : enables manual selection of kVp, mA, and mAs or time
settings for exposures
For detailed operating instructions for each of the above modes, proceed to the
required procedure (MANUAL, AEC, or APR [with or without AEC]) on the follow-
ing pages.
NOTE: In the sample screens that follow, dis-
played values are for illustrative purposes only
and do not necessarily reflect valid techniques.
