8. EVALUATION STAGE
8.1. Overview
Evaluation Stage enables the operator to evaluate treatment results based on post- treatment, contrast-
enhanced imaging. The contrast-enhanced images display the Non-Perfused Volume (NPV) within the
prostate tissue. Once the images are uploaded to Exablate Prostate workstation, they are overlaid with the
accumulated thermal dose.
The user can either scan treatment evaluation images (with- and without-contrast) directly from the
Exablate Prostate workstation or select post-treatment MR images from the MR console and import them
to the workstation. These images can be reviewed later in Replay mode.
Do not shut down the system prior to completing the post-treatment imaging and
removing the patient from the MR. Otherwise transducer motion during system shutdown
may cause severe imaging artifacts.
