Pull request overview

This PR extends the CEUS GUI workflow to optionally load a B-mode scan alongside the CEUS scan, display it as an overlay in the VOI drawing view, and add a “Export Video” feature. It also updates some Qt Designer .ui layouts (including the QUS ROI drawing UI).

Changes:

• Add optional B-mode path selection during CEUS image loading and load B-mode in parallel in the model.
• Pass B-mode data into VOI drawing and render a B-mode overlay with an adjustable alpha slider.
• Add an MP4 export path that composites CEUS (and optionally B-mode) with VOI border overlays.

src/ceus/seg_loading/seg_loading_view_coordinator.py	Threads optional B-mode data into the VOI widget and routes new noise-floor/enhancement actions.
src/ceus/seg_loading/seg_loading_controller.py	Handles new user actions for noise-floor computation and enhancement requests.
src/ceus/image_loading/views/file_selection_widget.py	Adds optional B-mode file/folder selection and includes it in emitted load data.
src/ceus/image_loading/ui/file_selection.ui	Adds UI controls for optional B-mode path selection.
src/ceus/image_loading/image_loading_controller.py	Invokes model B-mode loading when a B-mode path is provided.

• preview_modified_image() calls self._voi_drawing_widget.update_enhancement_cache(...), but DrawVOIWidget no longer defines update_enhancement_cache (it’s commented out). This will crash when preprocessing preview is invoked. Either reintroduce update_enhancement_cache on DrawVOIWidget or remove/replace this preview path end-to-end (including controller handling).

    def preview_modified_image(self, modified_image: UltrasoundImage, frame: int) -> None:

        """Show the preprocessed data in the VOI drawing widget."""
        if self._voi_drawing_widget:

• load_image() resets _bmode_image_data/_pending_bmode_load for a new load cycle, but it doesn’t stop an in-flight _bmode_scan_worker from a previous request. If a previous B-mode worker finishes after a new CEUS load starts, it can overwrite _bmode_image_data and even trigger image_loaded for the wrong pairing. Consider quitting/waiting the _bmode_scan_worker here as well (or tagging requests with a load-id and ignoring stale worker completions).

        # Reset state for new load cycle
        self._image_data = None
        self._bmode_image_data = None
        self._pending_bmode_load = False

        if scan_loader_kwargs is None:
            scan_loader_kwargs = {}
        
        input_data = {
            'scan_type': self._selected_scan_type,
            'image_path': image_path,
            'scan_loader_kwargs': scan_loader_kwargs
        }
        
        if not self._validate_image_input(input_data):
            return
        
        # Stop any existing worker
        if self._scan_worker and self._scan_worker.isRunning():
            self._scan_worker.quit()
            self._scan_worker.wait()
