Sundar Pichai, the CEO of Alphabet and its Google subsidiary, said yesterday that healthcare offers the biggest potential over the next five to 10 years for using artificial intelligence (AI) to improve outcomes. He vowed that the technology giant will heed privacy concerns.

US lawmakers have raised questions about Google's access to the health records of tens of millions of Americans. Ascension, which operates 150 hospitals and more than 50 senior living facilities across the United States, is Google's biggest cloud computing customer in healthcare.

"When we work with hospitals, the data belongs to the hospitals," Mr Pichai told a conference panel at the World Economic Forum in Davos, Switzerland.

"But look at the potential here. Cancer is often missed and the difference in outcome is profound. In lung cancer, for example, five experts agree this way and five agree the other way. We know we can use artificial intelligence to make it better," Mr Pichai added.

Google has spent several years developing AI to automatically analyse MRI scans and other patient data to identify diseases and make predictions aimed at improving outcomes and reducing cost.

US lawmakers asked the company in November to provide information about other health systems that provide information to Google, whether Ascension clients will be allowed to opt out of the project, and whether the data will be used for advertising.

Mr Pichai said there were already strong privacy protection regulations in place that provide a framework for Google to operate.
