Training a u-net for multi-landmark heatmap regression producing the same heatmap for each channel

I’m training a U-Net (model below) to predict 4 heatmaps (gaussian centered around a keypoint, one in each channel). Each channel is for some reason outpu

Monai : RuntimeError: Sizes of tensors must match except in dimension 1. Expected size 7 but got size 8 for tensor number 1 in the list

I am using Monai for the 3D Multilabel segmentation task. My input image size is 512x496x49 and my label size is 512x496x49. An Image can have 3 labels in one i

Is it possible to retrieve beam real world position from RT PLAN

I am currently working on some radiotherapy plan generation and I am trying to retrieve the beam source position from a DICOM RTPLAN file and point it on a rela

Why is there a difference in Intersection over Union (IoU) calculation while evaluating for same data using same model?

I evaluated the IoU score for the test dataset using the saved model. (model.evaluate(test_gen, steps) Also, I have calculated the IoU score for each image in
