dc.description.abstractTWO GROUPS OF SUGAR MAPLE (ACER SACCHARUM MARSH) LOGS WERE SCANNED USING AN X-RAY SCANNER TO IDENTIFY AND LOCATE THEIR MAIN INTERNAL CHARACTERISTICS. IN THE DESIGN OF THIS EXPLORATORY STUDY, FIVE LOGS PRODUCED FROM A FRESHLY CUT TREE (GROUP 1) AND THREE LOGS (GROUP 2) SAMPLED FROM A SAWMILL YARD, WERE SCANNED TO IDENTIFY THE VARIOUS WOOD TYPES PRESENT: ROT; KNOTS; COLORED HEARTWOOD; AND SAPWOOD. BASED ON THESE COMPUTED TOMOGRAPHY (CT) IMAGES, FOUR OR FIVE DISKS (20 MM THICK) WERE CUT FROM EACH LOG. BLOCKS OF 10 X 10 X 10 MM WERE THEN CUT FROM EACH DISK REPRESENTING AREAS OF EACH TYPE OF WOOD. THE GREEN DENSITY, BASIC DENSITY, AND MOISTURE CONTENT OF EACH BLOCK WERE MEASURED TO ASSESS WITHIN-TREE VARIATIONS BETWEEN LOGS AND WITHIN WOOD TYPE. CT GREY LEVELS IN THE CT IMAGES WERE THEN MEASURED FOR INDIVIDUAL BLOCKS TO ASSESS THE FEASIBILITY OF IDENTIFYING WOOD TYPES.
