Run the DCA X-ray output check
Acquire and evaluate the X-ray output profile with the DCA (Data Collection Application): set the scan conditions, apply Offset pre-processing and Re-Correct, calculate the mean channel data for a selected row, then graph the profile — the standard DCA-based check for isolating a data-acquisition problem.
Applies to
Aquilion 16 (TSX-101A) — DAS (data acquisition section) volume 2D201-065, section 5.4.2 "DCA test procedures," item (1) "X-ray output check" (p.67-72). Run from the DCA (Data Collection Application) console; for the DCA's own general operating procedures, source points to the system-software service manual 2D260-069E, which is outside this DAS volume's scope.
Personnel
Intermediate — operating the DCA software to set scan conditions, apply Offset pre-processing and Re-Correct, select the correct acquisition row from the row-selection table, define a Calc (ScanData) channel range, and read/graph the resulting profile; source assumes DCA familiarity and performs no PWB handling or bench measurement in this section (skill assessment derived from procedure content — not an OEM-stated skill level).
