Advancing Discovery with Trainable AI
Insightful and robust AI creation for pathology


Unlock Limitless Possibilities with HALO AI
HALO AI has you covered. Whether you’re looking to solve image analysis challenges in segmentation, classification, or phenotyping, the advanced deep learning networks of HALO AI are easily tuned for your specific application with the train-by-example interface.
Diverse and Powerful AI
Underpinned by modern deep learning networks, HALO AI provides a collection of segmentation, classification, and phenotyping tools for brightfield and fluorescence applications. Train a classifier to quantify tissue classes, to find rare events or cells in tissues, or to categorize cell populations into specific phenotypes.
AI-Powered Annotation
Use a point and click workflow to rapidly annotate images and develop training data.
Nuclear Segmentation

Choose between several trainable AI-based nuclear segmentation networks to optimize segmentation accuracy when nuclear morphologies vary.
Membrane Segmentation

Train AI-powered membrane segmentation networks to accurately delineate cell membranes for your specific assay.
Cell & Object Phenotyping

Quickly train a phenotyper to quantify cell types or objects of interest.
Slide Quality Control

Leverage a trainable AI-powered quality control network to detect common artifacts in H&E and IHC images.
Simple & Intuitive Workflow
Choose to integrate your trained HALO AI networks in multiple locations within HALO modules to perform functions including tissue classification, nuclear and membrane segmentation, and phenotyping. Alternatively, apply HALO AI directly to an entire study of whole slide images or to select regions of interest – the choice is yours.
Manage Variability
Extreme variability runs rife in image analysis but is no match for HALO AI. Common sources of variability include diverse morphologies, alterations of morphologies from staining protocols, differences in tissue quality, uneven staining, and more.
HALO AI can be easily trained to accommodate variability to deliver accurate segmentation and classification results across large studies. HALO AI can even be trained to work across vastly different stains such as PAMS, Trichrome, H&E, and IHC.

Exceptional Identification
Pre-trained nuclear and membrane segmentors available in HALO are advanced tools for nuclear and membrane segmentation, but when you need to optimize a network for a bespoke application, you need HALO AI.
As with the tissue classification and segmentation networks, you can quickly add training data with the AI-based annotation tool and train the network to optimally segment nuclei or cell membranes. And once trained, any HALO AI network can be incorporated into HALO modules for maximum utility.

Powerful Tissue Classification
The degree of variability encountered in pathology often demands an approach above and beyond a simple random forest tissue classifier.
HALO AI has two advanced pre-trained networks capable of creating high-resolution classifiers in brightfield and fluorescence, depending on how much training data and time are available for training and optimization.
Curious to see HALO AI in action on your images?

Advanced Phenotyping
Cell phenotyping can be used on any of the myriad supported image types to automatically assign cells into user defined phenotypes. Simply select a nuclear or membrane segmentation network, provide a few quick training examples, and train the network to identify phenotypes of interest.
Phenotyping is a highly effective and flexible tool to quantify cells based on morphology when biomarker information is absent and can assist with quantification and characterization of cells with complex morphologies, such as neuronal cells.

Great results, can't live without this instrument!
"Scientists can achieve lots of high-quality analysis data about figures by HALO software. Many functions of HALO are very helpful to study images, such as TMA, spatial analysis, high-Plex FL, and especially HALO AI. It is easy to operate. Its interface is simple, friendly, and convenient. Once we have problems, a Halo technician is able to help us to solve them in time."

Advancing Discovery with AI: Features of HALO AI
Quickly acquire training annotations in either brightfield or fluorescence with the new AI annotation tool in HALO AI. Simply point and click your object of interest to add an annotation.

Use real-time tuning in HALO AI to watch a network as it trains in real time. Toggle the mark up on and off to evaluate performance, choose to add training data, or change parameters on-the-fly.
Once a HALO AI model is trained, a probability map can be used as an alternative output to a traditional mask to evaluate performance. Use real-time tuning to select an appropriate probability cut-off for a given class and view the output in a heatmap where blue represents the lowest probability and red the highest.

Investigate results with interactive markup images where you can toggle on and off each population of interest. Interactive markups can be combined with probability thresholding and are especially valuable in exploring validation outputs.

Deploy your HALO AI models in the context of HALO modules for maximum image analysis utility. Choose to utilize one or more models such as nuclear segmentation, membrane segmentation, tissue classification, cell or object phenotyping, and/or SlideQC.
Leverage the three-part Train – Validate – Test workflow to address the question: How good is my HALO AI classifier? Quantitative metrics are output based on the type of network.
Speed up your HALO AI analysis by adapting your trained network for your specific GPU. Also, you can queue training jobs based on number of iterations or time and set it to run at the end of your workday to maximize productivity and evaluate multiple model variants.
