Data acquisition trouble ↔ cause matrix (Table 5.4-2)
When an Aquilion 16 scan shows one of four classic DAS-side image faults — a ring image, a streak shower, a shifted CT number, or a large image SD — start here: Table 5.4-2 cross-references each symptom against every component the source lists as a possible cause, then names the flowchart figure (5.4-18 to 5.4-21) that walks you through actually isolating it.
Applies to
Aquilion 16 (TSX-101A) — DAS (data acquisition section) troubleshooting chapter, source volume 2D201-065, subsection 5.4.3 "Flowchart for each troubleshooting" (p.79). This atom carries only Table 5.4-2, the symptom-to-cause matrix that opens §5.4.3 and routes you to one of four flowcharts; the flowcharts themselves (Figures 5.4-18 to 5.4-21) are separate atoms — see Related.
Personnel
1 technician · Basic — reading a symptom-to-cause reference table and selecting the matching flowchart figure; no measurement or disassembly is performed by this atom itself (skill assessment derived from the section's own content — not an OEM-stated skill level).
