A line trajectory X-ray tomography dataset of the Hugo de Groot bookchest

Summary

This submission contains tomographic dataset of a large wooden bookchest from the Rijksmuseum collection.

The data is made available as part of [Bossema et al., 2021].  

Apparatus

The dataset is acquired using the Baltograph X-ray scanner (https://www.balteau-ndt.com/), located in the Ateliergebouw of the Rijksmuseum, Amsterdam. This apparatus consists of the Baltograph Generator XSD225 with X-ray tube TSD225/0 (focal spot size is 1mm (640W) or 5,5mm (3000W)), Control Unit LS1, water cooling unit WCU3000 and manipulator system Seifert DP435 (C-arm and rotating table, 3 axes in total and rotation). The X-ray beam projects polychromatic X-rays onto a 1920-by-1536 pixels, 16-bit, flat detector panel with pixel size 127 micron (Baltoscope FPDIGIT13-127).

Sample Information

The object is a large wooden bookchest (73 cm width x 160 cm length x 75 cm height) from the Rijksmuseum collection, inventory number NG-KOG-1208 (http://hdl.handle.net/10934/RM0001.COLLECT.53787).
 

Experimental Plan

The data in this submission was collected to compare dendrochronological measurements on the reconstructed image using a linear scanning trajectory and a photograph of the radial/tangential section of the plank on the outside (see Figure 7 in [Bossema et al, 2021]). It was recorded with focal spot size 1mm, 150kV and 525W.

All raw data (i.e. no corrections) is made available in .tiff format.
