AB 460 opened the door. Most centers have not walked through it.
Since January 1, 2026, California imaging centers have been able to supervise contrast studies virtually. The centers that moved first stopped rationing contrast slots, stopped rescheduling patients, and started taking same-day add-ons that used to go to a competitor. In a market this tight, the center that can scan today keeps the referral. Tether gets you compliant and live in weeks, with the on-site personnel verification, technologist competency documentation, and imaging record access AB 460 requires already handled.
What changes when coverage is never the question
Stop rescheduling contrast patients
Grow volume without growing payroll
Technologists who walk in ready
Audit-ready without the paperwork
Live in weeks, not quarters
From first call to first supervised scan
Step one — the twenty-minute call
We scope your sites, modalities, operating hours, and current coverage. You get a straight answer on what your program looks like and what it costs, usually before we hang up.
Step two — we prepare your center
Hardware deployment, physician credentialing and state licensure, technologist training, reaction kit placement, and your supervision documentation. Setup is our job, not yours.
Step three — one button, seconds to a physician
Your technologist presses once and reaches a credentialed physician. Sessions document themselves. You get monthly QA summaries and a partner watching your state's rules.

Where California stands
AB 460 amended Health and Safety Code Section 106985 effective January 1, 2026 to permit a certified radiologic technologist to administer contrast under a physician supervising by real-time audio and video, with imaging record access and defined on-site personnel present. Tether's onboarding verifies every condition.
