Applying transducer arrays

Optune delivers therapy through 4 adhesive patches, called transducer arrays. These arrays are applied to your scalp. They are powered through the connection cable and box, which is powered by the battery. If you are starting treatment with Optune, applying transducer arrays will soon become a part of your routine. With the help of a caregiver, your head will be shaved and arrays changed at least 2 times per week. Do not wear the same set of arrays for more than 4 days at a time.

You can cover transducer arrays with breathable head coverings

  • If you’d like, you can wear a breathable head covering like a cap, hat, head wrap, or loose-knit wig over thetransducer arrays
