How do you trace the main sewer line in concrete?

Hi, Getting ready to plan a renovation of a 'bathroom' in the basement. Right now it's just a toilet with three walls for privacy...
I want to make it a real room and add a sink/shower to it. How can I figure out which way the drain lines run under the poured concrete floor? I want to dig in the right places and minimize the cuts needed to find a suitable tie in location for the new service drains.

Thanks, Matt
