Questions: Safe Exam Browser 3.3.2 - WK 11: Final SPI Mock Exam (Cumulathe) (Dage a3 of 00 - Physical Principles Instrumentation o During the course of a sonographic exam, what can you do to improve the image? a. Decrease the scanning depth. b. Increase the sector width. c. Increase the number of transmit focal zones and optimize their location. d. Use the maximum acoustic power. e. Use the lowest line density setting.

Solution Steps

To determine the best way to improve the image during a sonographic exam, we need to analyze each option provided:

• Option a: Decrease the scanning depth.

  • Decreasing the scanning depth can improve the resolution of the image because the ultrasound system can focus more on a smaller area, leading to better detail.

• Option b: Increase the sector width.

  • Increasing the sector width can cover a larger area but may reduce the frame rate and resolution, potentially degrading the image quality.

• Option c: Increase the number of transmit focal zones and optimize their location.

  • Increasing the number of transmit focal zones and optimizing their location can significantly improve image resolution and focus, leading to a clearer image.

• Option d: Use the maximum acoustic power.

  • Using the maximum acoustic power can increase the signal strength but may also increase the risk of tissue heating and other safety concerns. It is not always the best option for improving image quality.

• Option e: Use the lowest line density setting.

  • Using the lowest line density setting can increase the frame rate but may reduce the image resolution, leading to a less detailed image.

Based on the analysis, the best option to improve the image quality during a sonographic exam is to increase the number of transmit focal zones and optimize their location. This approach enhances the resolution and focus of the image without compromising safety or significantly reducing frame rate.
