Vessel and Plaque for Gary Seamans

blood vessel plaque for G.Seamans

Here is another stellar example of how the ETC groups work together.

The idea for giving College of Engineering donor and supporter Gary Seamans something created in the college started with a blood vessel. EMS staff Steve Struckman and Bill Jennings printed a 3" x 3" model of the ocular vasculature on the Fortus 3D printer, and then encased the model in clear arcylic. Next the acrylic block was polished and the edges smoothed. Doug Eltoft, a competent wood worker when not at his job as Chief Technology Officer, sawed a walnut (??) base, which he smoothed and finished (sanded? oiled?). ECS communication manager Diana Harris edited the explanatory text written by Li Zhang, the ECE graduate student who create the blood vessel model, and his advisers. Then John Kostman, service manager in EES, used the VersaLaser to engrave the explanatory text (obverse), the University of Iowa seal, and the notation that the model was created for Gary Seamans on the top side.

Dean Alec Scranton gave the assembled vessel and plaque to Gary Seamans, who spoke at graduation in May 2013.

The text on the obverse side of the plaque:

This model is a 10x scale of the choroid vasculature in the human eye. This 3D print, the first to our knowledge, shows clearly the choroid’s layered structure. The most important contributor to keeping the retina supplied with oxygen, the choroid has been implicated in many eye diseases including age-related macular degeneration. Tracking changes of choroidal thickness or vessel volume may improve the diagnosis and management of eye diseases.

This model was prepared by Li Zhang, graduate student in Electrical and Computer Engineering and part of the Iowa Institute for Biomedical Imaging (IIBI), under the supervision of Milan Sonka and Michael Abramhoff at The University of Iowa. This model was imaged using Spectral Domain Optical Coherence Tomography and printed on the Fortus 400mc 3D printer in the Engineering Machine Shop, part of the Engineering Technology Centers in the College of Engineering.
