Question

Which of the following may reduce the out of field artifact?

a. increasing the scan FOV
b. reducing the reconstruction FOV
c. reducing the slice thickness
d. increasing the matrix

Answer 1

To reduce the out of field artifact in imaging, you can increase the scan FOV, reduce the reconstruction FOV, and reduce the slice thickness.

Step-by-step explanation:

To reduce the out of field artifact in imaging, you can take the following steps:

1. Increasing the scan FOV: By increasing the scan field of view, you can capture a larger area of the body, reducing the chances of artifacts occurring outside the designated field.
2. Reducing the reconstruction FOV: By reducing the reconstruction field of view, you limit the area over which the image is reconstructed, minimizing the possibility of artifacts occurring outside the intended field.
3. Reducing the slice thickness: A smaller slice thickness helps improve spatial resolution and reduces the likelihood of artifacts spreading out of the desired imaging field.

Thus, options a, b, and c may reduce the out of field artifact.
