ROI DETECTING IN BRAIN

anyone could help on which function i should to use for auto detecting ROI in brain

please any help would be apprictiate

[Nikhil Sapre]

Your questions is very vague.

What does ROI mean? What does auto detecting ROI in brain mean?

Can you please give more context and more details to your question?

[Kevin Holly]

I understood ROI to be region of interest, but vague nonetheless.

[Adam Danz]

Many ROIs are defined by physiological responses which, of course, cannot be isolated by images of the brain. If you're refering to anatomical ROI isolation, there are already lots of programs that do that (I used caret). Of course it's also possible to do this in Matlab but I haven't looked into whether there is already a toolbox for that and I probably wouldn't use it anyway since there are already established tools for this widely accepted in my field.

[MOHAMED GILANI]

what i mean is to automatic selection for this regoin of interest. for ex, hippocam in brain. and isolate it from other parts of brain

[MOHAMED GILANI]

@Adam Danz is caret support it? i mean segmentaion and ROI

According to the link I shared, it has been replaced with https://www.humanconnectome.org/software/connectome-workbench

Answer 1

@MOHAMED GILANI, attached is a non-deep learning method that may help somewhat, at least for high contrast tumors. It uses traditional thresholding.

[MOHAMED GILANI]

SIR

im focusing more on hippocampus detecting which more harder to apply thresholding

any suggesting?

[Image Analyst]

My only other suggestion is to see how others did it. Besides looking at the VisionBib Image Processing literature link I gave you in the other answer, you can also search the medical literature "PubMed". You can probably get a more robust solution there than you ever will here, because there people worked on it for months or years and published it in peer reviewed journals.

[Image Analyst]

An ROI in the brain? Well that's pretty vague, like Adam said. I'd start your search here:

[yanqi liu]

sir，may be use DeepLearning method to train a segment model，such as unet to detect and seg，such as

do u have any ref to check?
