Summary | 0003452: Unable to use Volume module Threshold widget in a meaningful way | ||||
Description | For the attached dataset, I need to hide the values that are 0, and I want to see everything else (threshold out everything 0). Can someone instruct me step by step how I can do this? I am unable to accomplish this simple task with Volumes modulemanual Threshold feature. | ||||

Reminder sent to: finetjul @Julien - is there an easy fix for this? |
|
to make sure there is no ambiguity, here's the code that accomplishes what I tried unsuccessfully to do via the Volumes threshold widget: v = slicer.util.getNode(name) |
|
Here is what I do on Windows 7:
I would admit:

Julien: I confirm I can follow your steps and it does work on Mac. However, the steps are a mystery to me starting from "- Move the W/L right handle down to 0.016". In Slicer3, I was able to just type in the actual values for window and level - I didn't need to read the manual or ask how to do that. FYI, it is not just me who has problems understanding this GUI: I asked both Ron and Steve how to accomplish the task, and they did not have an answer. |
|
Andrei, I am not saying the Volumes module is intuitive, I agree it is not. Concerning the W/L, there are different issues you reported:
For a) I am not sure what can be changed. feel free to suggest something else. Again, I know there are lots of issues with the W/L and Threshold. |
|
Julien, the reason I mentioned the mystery of W/L is because you list it in the steps to set Threshold, and I was not sure if it is needed or not. I understand now you probably did it just to have a meaningful visualization. What is confusing to me is that the values for Threshold (and same for W/L) are constrained by the popup widget, which is not visible. My intuition is that if GUI says "Threshold", I should be able to enter the numbers for threshold, and apply them. Specific suggestions for the GUI: 1) add 2 simple spin boxes that allow to set the numeric values for W/L and Threshold bounds (2 each), perhaps include regular double slider widget - this is how we had it in Slicer3 I think What do you think? |
|
It is indeed an annoying issue but there are workarounds and overall it does not seem to actually block any particular project. |
|
Retargeting stale issues to backlog. |
