When it comes to full field digital mammography units, by far the most delicate (and expensive) part on the unit is the digital detector. If you're considering the purchase of a digital mammography unit, we encourage you to inquire after your vendor's handling of the detector.
The following is what Block Imaging does when we work with digital mammo detectors:
Each digital mammo unit is put through a battery of tests by trained engineers. This ensures that we are purchasing a functional system with image quality at (or above) OEM specification. The video below, taken from the inspection of a GE Senographe 2000D is an example.

Before every de-installation, our project manager ships one of our specially-designed detector boxes to the site so the detector can be placed inside immediately upon removal from the machine. This additional measure of care involves extra time and money, but these carefully padded crates have yielded a high success rate in shipping digital detectors across the country and around the world. In addition to padding, each crate contains a layer of temperature-control phase-change material to prevent rapid cooling or heating of the detector during transport.
Below is a rendering of the contents of a detector crate:

We understand that each digital mammography system purchased from us will be scanning patients somewhere in the world in an effort to detect cancer. Consequently, we want to make sure each of them has been cared for in a most excellent way and is delivered fully functional.
