jpeg format does not create a true volume data set. the ultrasound transducer sweeps across the target and collects a gajillion slices of data. raw data does not convert nor does jpeg, or img, btm, or a number others. The only formats that collect the entire data set seems to be Dicom, 4-D View either compressed or not and, potentially a cartesian file though these have not proven to be reliable.
Thank you Bobby, you have given me some hope and I hope we can continue our dialog going forward.
I am calling Materialise who has Mimics...they have mentioned that they have something that may work, I just don't know from where. If they can give me a basic description of what it is, I will forward to you.
Also, the Dicom standard is pretty generic maybe that would work. Do know anything about that?
Right! But I can export from it to another program if it exists. That's where I need help. It needs to go into a segmentation program before Mimics etc.
So how and where and who might be able to do that? I know it exists, I have the proof that it works but I need to find some one or something that can write this in a very basic way and put the idea back into business.
It' time for me to say good bye for the day. I can't thank you enough for your interest. If you stumble upon something before the morrow, please give me a shout at my e-mail address. I will be checking that later this evening but for now it's off to the chamber for intrusive behavior propagated on gravid ladies.
These volume files can be opened in any numer of different files, mostly in a dicom standard or cartesian coordinates. The cartesian coordinates do not seem to work very well at all. So what I need is a segmentation program between the 4-D View program and a conversion program that actually contsructs the volume in a STL type file such as "Mimics" from Materialise. They are able to contruct in STL formats from CT and MRI not to mentions CAD programs etc..?
One of the volume reconstruction programs that I use is called 4D View. If the volume is saved in that format then the extension is .4dv. I'm not sure what the extension would be for other formats in that the 4D View is a prioritized software from GE Healthcare that is used by myself and the perinatologist with which I work.
like a cone with a concave top and convex bottom. This then fills into any number of file types including cartesian etc. directly from the ultrasound machine.
The STL files are basically only accept cubes ie; XYZ coordinates.
This is how I've been lead to understand it in the most basic form.
Stereolithographic files are oriented in cubic pixels while ultrasound volumes are oriented in conic voxels.
Stereolithography is a type of 3-D printing which constructs objects from the bottom up by layering material into whatever it may be. (see rapid prototyping)
There are ways of converting 3-D Voxels into the STL pixels. I just don't know how to do it. Go to forever-baby.com. That is what it is all about. Those were constructed by a vendor who wanted to take over the concept as his own and has since been kicked to the curb by me. Now I'm in the dubious position of trying to work this out on my own with which I have no free time to accomplish due to work load and other commitments.
Once you see the finished product on the web site, you will have an idea of what I'm trying to do.
I suppose you're being a bit modest about your abilities, which is well taken. He is quite proud of you.
Jimmy suggested I give you a try.
I am trying to find a way to segment an ultrasound volume data set from either cartesian files or DiCom standards and convert to a stereolithographic file.
I have tried a number of different avenues with other people but the usual and standard problems and frailties of the human condition continue to be an issue.
Might you have an idea of where to begin (once again for me), and what can I provide to you in order to give you more information and the myriad of challenges that continue to present themselves.
Thanks in advance for even considering this.
