Scan Anatomy: Ready Brain

Ready Brain protocol acquires a 3D localizer that calculates the brain center. The location of AC and PC has some correlation with the shape of the head and the anatomy of the individual patient. The system calculates the localizer for the ACPC line from a 3D data set that is named Registration Localizer (Ready Brain 3D Loc) that uses 3D and 2D matching technology. Add Auto Scan to this mix, and you have a one-touch protocol.

Ready Brain calculates the angle of the scan plane that is closest to the plane determined by the ACPC line. Ready Brain also calculates the center of the brain, which is not necessarily the same as the mid-point of AC and PC.

• If you want to make scan parameter changes to a task, select the task in the Workflow Manager before you acquire the Ready Brain 3D Loc. Click Setup, make your changes and click Save RX. The modified task is linked to the Ready Brain post process task as soon as it moves to a Done state.
• These Ready Brain calculations may be compromised for the following patients and thus it is recommended that you not use Ready Brain:
  • Pediatric patients under one year of age typically result in an error that occurs because the 3D localizer axial image used to calculate the scan angle for the mid-sagittal scan includes the lateral ventricles. The error also can be due to the difference in the brain tissue contrast in pediatric patients in comparison with adult patients. This can also occur with adult patients if the patient head size is approximately 80% smaller than the average adult head.
  • Patients that have brain pathology at the longitudinal fissure. Ready Brain may not be able to determine the mid sagittal plane, which results in an error when determining the brain center and scan plane angle.
  • The patient's head is significantly deformed.
