Botanic Art using CT scan and reconstruction.

February 14, 2013  •  Leave a Comment

Having used the mammography machine to reveal the inner details and lines in flowers (see Floragraphy gallery on this site), it is natural to explore the use of other modes of medical imaging to create botanic digital art.  I have teamed up with my colleague and award winning digital artist and radiologist Dr Kai-hung Fung for this project.  Incidentally if you google Kai-hung Fung, you will see his stunning pieces using CT scans of the human body and other biological specimens. The scans are reconstructed into 3D objects which can be manipulated and viewed from any angle including projections from within the flower of stem.

A view from inside the teasel (Dipsacus fullonum) seedhead looking up towards the tip of the seedhead.  The blue core is the central dense core.  The overall effect is what I imaging travelling through a worm hole may look like.

 

 

 

 

 

 

 

 

 

Another interesting feature of this imaging technique is the ability to adjust the transparency of the outer layer to reveal underlying structures which are not seen with visible light imaging as shown below.

The transparency is even more evident in the scan of the Leucadendron seedhead.

The color rendering here is done using the density value for each voxel including the use of the rainbow technique algorithm.  For more images of CT scan imaging please go to my Botanic Art gallery on this site.

The potentials of the technique are not limited to 2D images shown above.  The same scan can be reconstructed and viewed on 3D monitors and 4D images where one can view the images as the 'camera' fly through and into the subjects.
