material_xray_table — TOMOGRAPHY `spectral_xray` op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.material_xray_table() -> 'list' (to call the implementation directly, import materials; materials.material_xray_table() -> 'list'; from the registry, opstomography.get("material_xray_table"))

Usage

List the materials whose X-ray column (mass attenuation coefficient μ/ρ) can be looked up.

> The detailed description below is the original text — the summary and the headings are translated.

返り値: 1 材料 1 行の dict(name, kind = table / mixture / element, density_g_cm3, composition ((記号, 質量分率), …), optical(光学の表にも同じ名前のレコードがあるか), reference)。元素 49 種と NIST の化合物 20 種は NIST SRD 126(Hubbell & Seltzer)の表そのもの、それ以外は XRAY_SOLID(と電子線の表)の組成から混合則で作る。範囲は 1 keV〜1 MeV(表の外は外挿しない)。

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.

Ops the type connects to (they accept `table` as input)
