Implementation Considerations

• Requires expertise in stereotactic surgery, ultrasound physics, and microbubble handling.
• Needs instrumentation including function generator, power amplifier, motorized linear stage, needle hydrophone, and imaging modalities (X-ray, bioluminescence).
• Demands cross-team standardization of animal preparation, catheterization, and transducer calibration procedures.
• Involves adaptation considerations for different transducer frequencies, targeting coordinates, and model systems (e.g., rat vs. mouse).
• Practical limitations include the need for surgical skill in tail vein catheterization and potential variability in skull thickness affecting ultrasound transmission.
