redering a 3d image from an intensity stack

[Roberto83]

Hello Ben,

In the IMAGE Proc and 3D array.vi I have two plots, one of the image and one more of the image processed by the SOBEL filter. I actually need these plots, that's why I did not remove them.

This is my latest update to the Image processing vi Ben,

I added a dispose image icon. I used the dispose all images option (TRUE) yet I am only able to process 99 images The memory of my computer is 1GB and the size of each image is 1MB.

I think I should be able to process more images than that, unless I am doing something wrong that I am not taking into account.

Hi Roberto,

Thank you very much for the images and the explanation of what we are seeing.

Thoughts;

1) In the code I posted there is a case structure used to replace the "0" values with NaN. Try modifying the case so it replace "0..16" or there-abouts. This will reduce the number of points plotted and will also help to "clear the fog" since your bubble region has higher values.

2) You may want to filter and down sample your data. Since you are not looking for single point info but rather regions you may be able to clean-up the graininess while also reduce the size of teh data set being plotted.

Again, thank you for the images.

I (and many others here ) are engineers and scientists and there is nothing like new and unique views of the world to keep us entertained.

Thank you!

Ben

Hey guys,

I am new to LabVIEW, but have a project for my electronics class, to make a PET scanner. I have to write a vi illustrating PET scanner technology for detecting  brain tumors. Show the detection system, the  image processing techniques, the  backgrounds and the diagnosis process. Any ideas of how i can do this? Would really appreciate that

That sounds like a pretty interesting project.  We have a number of tutorials to help you get up to speed with LabVIEW pretty quickly.  As far as your project goes, what kinds of inputs/outputs do you need?  What kind of processing will need to be done?  Feel free to reply if you have any specific questions.

Well I need to create 2D image of a brain, not necessary has to be a 3D, with a little tumor on it somewhere. Then some PET blocks that absorb the gamma rays coming from the brain. The blocks have to around the brain, so they would detect the exact position of the tumor. That is all that needed. I am completely lost in this project, of what and how to do all these on labview, so would really appreciate some help. 

Thank you

Here's a good example of how to display an image when you press a button.  You might be able to make use of this when displaying pictures of the brain.

As far as the tumor positioning algorithm, you're going to have to derive the mathematics needed for this, and then model that function.

[Murad_M]

Well, i do not need to do any positioning algorithm for the tumor, my professor told me that i can just put two picks up together, one of the tumor, and the other of the brain, just pasically put two pictures up, or jpeg. I just cant figure out how to do the gamma rays and the blocks that would absorb them, any suggestions on that?
