Aug 1, 2025

Month 2025-08: Bluesky/ophyd-async delivered a significant ROI analytics capability by implementing the NDROIStats plugin to compute basic statistics for multiple Regions of Interest (ROIs). The work includes per-ROI classes and a collection, with configuration for ROI names, dimensions, and statistics, enabling ROI-level insights and ROI-collection processing within existing imaging analytics workflows.

In July 2025, delivered end-to-end imaging integration for the ViSR beamline in DiamondLightSource/dodal, enabling robust imaging workflows and clearer detector semantics. Implemented Mako camera integration for ViSR imaging experiments via mako(); configured AravisDetector for the imaging setup; and standardized detector function names to reflect experiments (oav -> spectroscopy_detector, sample_det -> imaging_detector). Fixed detector naming inconsistencies to reduce misconfigurations and improve maintainability, aligning with project conventions.
