Question: Is it possible to get to individual Pixels in dicom image? about dicom HOT 3 OPEN

Hi there! Sounds like you need a couple pieces

1. Tumor Segmentation in a set of CT slices
2. Registration of the NM slices to the CT image slices (align them in 3D space)
3. Compute the metric of interest

Doing 1 programmatically will probably require some kind of ML model if the radiologist hasn't already segmented the tumor. You can google CT tumor segmentation to learn more. There are various registration algorithms as well, some ML based and some heuristic based (worth googling with these terms as well).

is my only option to change one of these vertical dicom images to a regular png and examine to find the tumor (possibly lots of images from up to down)? or is there a different way?

it might be easiest to go slice by slice yes, but your model may take in adjacent "context" slices as well for help.

This library could potentially help you preprocess dicom image slices, but if you're going to be doing a lot of modeling work, it may make sense to do the whole project in python (where libraries like pydicom might be helpful).

I have considered potentially building python bindings for this library, but that would only be worth it if there's a performance benefit because IIUC pydicom is pretty complete as it is.

Hope this is a helpful starting point, and good luck!

back with more questions
I looked at the API, didn't see a way to write one vertical image out (is there once and i'm just blind?)
say i read the file using dicom.ParseFile and then i want to go through and write out all the (PNG?) images that i can vertically for my CAT scan
and then i will process each resuting image to find the tumor

i'd prefer not to switch to python, i have lots more experience with Golang

@suyashkumar Is it possible to write out an image (PNG, JPG, whatever) from DICOM given all the x/y and z values?
