AI Powered, Pathologist Driven

Enterprise Digital Pathology Platform

State-of-the-Art Anatomic Pathology Software

HALO AP® is an AI-powered, pathologist-driven diagnostic pathology platform that enables primary diagnosis, remote working, and other routine workflows in anatomic pathology. In the video below, learn from a practicing pathologist how HALO AP improved patient care in their lab.

Collaborate with Colleagues Near and Far

With just a few clicks you can send out cases for a second opinion, resulting in improved patient care, reduced turnaround times, and eliminated shipping costs.

HALO AP enables pathologists to expand their reach by receiving inbound digital consults.

Future Proof Your Lab with AI

HALO AP includes industry-leading AI for enhanced workflows, research, and diagnostics. Quickly deploy off-the-shelf AI tools with HALO Clinical AI Solutions, including HALO Prostate AI (CE-IVD), Breast IHC AI, Lung PD-L1 AI, and SlideQC BF. Third-party AI tools, including algorithms from Lunit and Deep Bio, are also seamlessly integrated via an open architecture.

Prefer another AI or image analysis solution? Ask us how you can leverage our application programming interface (API) to easily integrate any AI or image analysis tools of your choice.

Customized and Secure Deployments

HALO AP offers on-premise or cloud-based deployments that work within your IT framework. With enterprise-grade administration, you can easily scale the number of users as your lab grows and configure roles and permissions.

Our Cloud Services division helps organizations migrate to, manage, and optimize their cloud deployments, delivering a highly performant, flexible, and secure environment. You can count on our AWS Certified Solution Architects, Technical Solutions Team, and our knowledgeable applications support.

HALO AP Integrates into Existing Laboratory Frameworks

HALO AP works with your laboratory information or laboratory information management system (LIS | LIMS) instead of replacing it. Access the right data at the right time by integrating with your LIS | LIMS, eliminating the need to move between platforms. Open, API-first technology supports bi-directional connectivity to any application.

True Interoperability

HALO AP is compatible with files from all major scanners and our staff are well-versed in data migration, with expertise integrating many common LIS | LIMS systems in enterprise-wide deployments.

Conducting research? Feed your pipeline using the option to export deidentified cases and manage the images with the HALO Link collaborative image management system or another IMS.

Comprehensive Integration, Training, and Support Services

At Indica Labs, we take pride in providing top-quality support. Our applications team provides comprehensive software training, and our technical teams will support your IT department with all aspects of deployment.

Already using an image management system? We understand that the idea of moving to something new can be daunting. It may not be as hard as you think! Reach out to us to find out how simple transitioning can be.

Features of the AI Powered, Pathologist Driven HALO AP® Platform

Our ergonomic viewer is as intuitive to use as a microscope and lets you quickly review slides without requiring special input devices, yet cleverly reduces mouse mileage, click-frequency, and mouse fatigue.

HALO AP automatically organizes images and metadata into cases. An ergonomic case viewer integrates digital slides, synoptic reports, gross details, and patient information. Rapidly evaluate patient history with links to prior related cases.

HALO Clinical AI, including HALO Prostate AI, Breast IHC AI, Lung PD-L1 AI, and SlideQC BF seamlessly integrate into HALO AP. In addition, labs can deploy third-party algorithms from Lunit and Deep Bio without ever leaving the platform.

Future proof your lab by bringing in AI algorithms and traditional quantitative IHC, ISH, and IF image analysis assays. Develop, validate, lock, and deploy assays to streamline the workflow for pathologists and technicians with little to no experience with image analysis.

HALO AP offers a wide range of tools to enhance the process of collaboration and consultation: run tumor boards, request second opinions, and provide second opinions to other pathologists.

Modernize tumor board preparation by quickly assigning cases, slides, and regions with notes. Instantly recall and navigate to histological regions of interest with a single click and quickly add any case notes.

HALO AP streamlines clinical trials across multiple hospitals and CROs by enabling coordinators to create, manage, and monitor trials from a single interface. The blind scoring feature simplifies blinded workflows, making clinical trials, research studies, and system performance validation easier to conduct. Results can be easily exported for downstream analysis.

Whether you’re using CAP, ICCR, RCPath guidelines or your own proprietary synoptic reporting forms, HALO AP makes it simple to develop customized synoptic reports and collect high-quality histopathologic data.

HALO AP allows your lab to personalize workflows with an intuitive custom assay builder. Establish the flow of work, reporting needs, and define specific instructions for tasks.

Great Customer Care

“Excellent customer care given post installation and training has been really hands on. Any issues are swiftly dealt with and feedback is always welcomed from the Indica team. Katie especially has been really supportive and has made the integration of digital pathology at NUH smooth and relatively stress-free.”

Niamh Longwill


Great software, very easy to use!

“I use HALO AP every day in my working environment. I find it very easy to use and it does exactly what I need it to do to carry out my job. The Indica team that deal with NUH are very friendly, attentive and always respond quickly to queries. They listen really well to feedback and are always asking how they can improve HALO AP. I have used other Digital Pathology IMS's in the past, but this is my favorite by far.”
