Create a 3D image from a series of slides?

3d laser scanner for 3d printer image

Vincent

Hello,

I want to take a series of slices of tissue made at several micrometer thickness and render them into a 3D image, so as to calculate a lesion volume....any suggestions?

I'm interested in software available to do this, and ideally, envisioning: imaging all of the slices with a camera interface then "layering" them on top of one another to create a 3D image and analyze the volume of a lesion within the tissue.

Thank you.

"slices of tissue" slides ( tissue lesions )

in someways it is the other way around where you have the whole object, and map the 3d image as whole, then dissect digitally with layers as slices to divulged anomalies or lesion ,

not clear as to aspects of re-rendering virtual solid from layering,

What can I use to cast a mold from stone without hurting the stone?

disciple

I'm new to this, but does anyone know what medium I would use to make a mold from a stone. In other words, There is an old building with a beautiful design sculpted in to it. I want to copy this design. I know there is a material out there that I can press against the original design and make a mold of it and then cast the design in plaster. I just don't know what material I would use to do this without hurting the stone.... Help!!!

Answer
I think the sculpey or any clay will work. If you use normal clay, any residue left will dissolve in the next rain, just don't use brown clay on light stone... if you use water based clay you would have to cast your plaster into the mold while the clay is still wet.
As the clay won't be very stable just on its own, you should consider making a mother mold on top of that. That is a hard shell, which just gives support to the soft part of your mold so it doesn't deform. It depends on the size of what you want to copy if you need it. You could make the mothermold from plaster bandages, but don't put plaster directly on the stone.
Before you start, consider carefully the shape of what you want to copy and where undercuts are and where you have to put in parting lines. What technique you use for mold making really depends on the exact shape of what you want to copy. If the structure is something complicated, you may want to practice how to make molds from more simple structures first so you are aware what causes problems and get some experience in how to solve them.

Another completely contact free method is if you happen to be at a university where they have a 3D laser scanning camera you can borrow, you could use the 3D laser scanner then make a model of your structure in the computer from the scans. That you could print out using a 3D printer. that way you can scale the model to any size (though anything large will be expensive to print)
