5 Common Replacement Parts for Hologic Selenia

Don't take this blog the wrong way; the Selenia isn't any more likely to break down or need new parts than other makes or models, but when breakdowns do happen, the following parts are the ones our Parts Team gets the most requests for. 

Detector (Array)

This detector, or detector array, is by far the most costly part on a Hologic Selenia. Pricing will be determined by which type of detector you are looking to replace as well as the detector’s date of manufacture.

The lifespan of a given detector will vary depending on usage but, anecdotally, we’ve seen detectors (2010 or later) last between 5-9 years. While there is no perfect correlation, it goes without saying that a newer detector should have a longer “lifespan” as compared to an older detector. If you intend to order one, be sure to check the part number below against the part number of your existing detector. There are two types of detectors for Selenia systems: 

Type of Detector


Price Range

$20,000 - $40,000

$35,000 - $50,000




X-Ray Tube

Selenias can be outfitted with one of two different types of X-ray tube. Take a look at our Selenia tube blog to determine which tube you need.
