Earlier this year Lakes Radiology was approached by Scion in Rotorua about using MRI and CT as part of a research project to assess the amount of water in wood. This paper reviews the process of setting up scan protocols, problems encountered and how they were solved, the significance of using MRI and CT, how the information obtained from the scans has assisted the researchers and what has been learned from this experience.

Session 2 / Talk 3
11:22 – 11:33
HEAPHY 1 & 2
Scion - Crown Research Institute dedicated to improving the international competitiveness of the New Zealand forest industry and building a stronger biobased economy.
Lakes Radiology - TRG Group – private medical imaging facilityBackground - Who
Slobodan the researcher
Delia the MRT
Kiln dried wood (KD) – dries from the outside –resulting in cracking and warping
Dewatered wood (DW) – basically replaces water in wood with alcohol which is then extracted – wood dried quickly from the inside – minimise cracking and warpingBackground - Wood drying processes
2nd series – de-watered wood, Green, 3xDW, 5xDW, 10xDW
3rd series – unexpected results therefore re-scan after 2xDW and 10xDWResearch Series
Talked and asked questions – resulted in some minor adjustments to the research
To get everything set on the trial scans, minimise errors, variables – check all parameters match
If there are options (e.g. kernals) give all for analysis
Revise CT and MR physicsWhat have I learned?
