On what basis should spatial resolution be tested?

Testing spatial resolution on a weekly basis is important for maintaining image quality in imaging systems. Weekly assessments allow for timely identification of any degradation in spatial resolution, which can affect diagnostic capabilities. Regular monitoring can help detect changes in system performance due to factors such as equipment wear, changes in the imaging environment, or variations in technique. This frequency is also consistent with best practices in quality assurance protocols, which emphasize regular testing to ensure that the imaging system continues to operate within established performance parameters. By testing spatial resolution weekly, facilities can ensure the accuracy and consistency of images produced, thereby safeguarding patient care.
