CLO 8: Analyze the relationships of factors that control and affect spatial resolution

spatial resolution: refers to the smallest object that can be detected in a digital image

• Increasing focal spot size – spatial resolution decreases
• Decreasing focal spot size – spatial resolution increases
• Increasing SID – increase spatial resolution
• Decreasing SID – decrease spatial resolution
• Increasing OID – decrease spatial resolution
• Decreasing OID – increase spatial resolution
