About the project:
iDgital is a cloud-based SaaS application that manages orders for Radiologists and can resolve clients’ issues. Clients are hospitals and groups of hospitals that are situated in different countries around the world.

This product team develops a Node.js/Angular web application in the healthcare field. All deployments are containerized in a large distributed architecture. We have co-developed a Healthcare API with Google that is central to our solution. The product has been developed from scratch and we are already in the release phase, so the ready part is that something used by clients from different countries. We will increase in multiple times in terms of clients soon, now we support around 100 facilities, soon this amount will be over 500.

Besides maintaining the product, we are working on new custom and technical features, improving the performance of the platform, and a few new major milestones in progress, e.g. on-prem version for the current SaaS application, improving the mobile app (IOS, Android), integrating a few additional ways of receiving information from the hospitals. Also, we have a few subprojects based on iDgital architecture.

The Digital Assistant performs a variety of specific tasks on behalf of the physician, making it acceptable for the physician to focus solely on the current conditions of their patient. Along with the Digital Assistant ML platform offering end-to-end image and data processing, the radiologist gains quick access to the complete and accurate origin of the information.

IDgital offers an end-to-end Radiology Solution that brings the power of modern computing technology to the field of Radiology in a meaningful way, while remembering that our goal is to always assist the radiologist, never to replace them.
