- Approval order statement
- approval for the Exablate Model 4000 Type 1.1 System software version 9.0.1 to be compatible with Philips 1.5 Tesla (T) and 3.0 T magnetic resonance imaging (MRI) scanners, and the hardware and labeling were modified accordingly as a result of this proposed change. In addition, the P150038/S036 application proposed the following changes to the subject device:• Expanded tractography support, to allow the display of overlapping anatomical structures.• Added baseline thermometry averaging (compared to approved baseline calculation using the last “cold phase” image), for enhanced sound-to-noise ratio (SNR), within approved specifications.• Added a visual indication of auto-calibration process bar and tracking planning scan acquisition.• Enhanced cavitation monitoring mechanism requirements, to further improve the robustness of the monitoring to sporadic noises and reduce false cavitation alerts.• Added additional thermometry protocols for GE and Siemens MRI scanners as additional options for users.
