How to get correct image coordinates from mouse click in Cornerstone.js?

I’m developing an Angular-based DICOM viewer using Cornerstone.js and I need to map mouse click positions to image-space coordinates i.e., the true pixel coordinates within the original DICOM image.

Currently, the coordinates I get change when zooming or panning, which means I’m likely mixing up screen/client coordinates with Cornerstone’s internal viewport transforms.
