The desired spatial linearity range for a SPECT gamma camera is between which values?

The desired spatial linearity range for a SPECT gamma camera is essential for ensuring that the image interpretations are accurate. A range of 0.2 to 0.6 mm indicates that the positioning of detected gamma-ray emissions aligns closely with the actual source of the radiopharmaceuticals within the body. This accuracy enhances the precision of the images produced and is critical for effective diagnosis and treatment planning.

Spatial linearity refers to how true the position of detected activity is compared to its actual position. A tighter range ensures better image quality and reduces the likelihood of misinterpretation, which could lead to clinical errors. Operating within this range helps in maintaining high standards of quality control, ensuring that the SPECT camera provides reliable and validated imaging results.
