SPI Mock Exam Verified Solutions How does increasing transmit power affect patient safety? ️️Increasing transmit power boosts image brightness and penetration but also raises patient exposure, so it’s used carefully to maintain safe levels. What is the role of frequency in determining axial resolution? ️️Higher frequencies produce shorter wavelengths, which improve axial resolution by allowing finer detail along the ultrasound beam’s path. Explain how spatial pulse leng...
