Check X-ray output with the DCA (acquisition, mean calculation, graph)
Acquire a scan with the DCA (Data Collection Analyzer — expansion *(derived)*, not spelled out in this section's source text), apply Offset pre-processing and Re-Correction, calculate the mean channel data for a selected detector row, then graph the profile — the first of the DCA-based checks this software volume describes for correcting a data-acquisition-section problem.
Applies to
Aquilion 16 (TSX-101A) — Software volume 2D260-074, section 2.4.1 "x-ray output check" (p.22-28), the first of the DCA Test Procedures in §2.4. Source frames the whole §2.4 plainly: "The DCA operating procedures that are often used to correct a problem with the data acquisition section are described here" (p.22). A companion procedure in a different source volume — the DAS (data acquisition section) volume 2D201-065E*D — documents this same check under its own §5.4.2 item (1) (p.67-72); see Related, toshiba-ct-aquilion16-das-dca-xray-output-check (already authored).
Personnel
Intermediate — start the DCA, set scan conditions and acquire, apply Offset pre-processing and Re-Correct, pick the correct row-selector value for the acquisition's slice count, define a Calc (ScanData) channel range and read the result, then build and read a Line/Mean graph of the profile; source assumes DCA familiarity and involves no PWB handling or bench measurement in this section (skill assessment derived from procedure content — not an OEM-stated skill level).
