Correction tables in nuclear imaging are utilized primarily for what purpose?

• A. Detector alignment
• B. Uniformity correction
• C. Contrast enhancement
• D. Spatial linearity correction

Answer: (B)

Correction tables in nuclear imaging are primarily utilized for uniformity correction. Uniformity refers to the consistent response of a detector to radiation across the entire field of view. When a nuclear imaging system is used, conditions such as variations in sensitivity of detectors, differences in filling of the gamma camera’s collimator, or uneven distribution of the radioactive source can lead to inhomogeneities in image quality. By applying uniformity correction tables, adjustments can be made to compensate for these inconsistencies, ensuring that the images produced are accurate representations of the distribution of the radiopharmaceutical within the patient. This correction is vital for improving the diagnostic quality of the images, as it minimizes artifacts that could lead to misinterpretation of the data. The other options represent important concepts in nuclear imaging but do not primarily encompass the main purpose of correction tables. For example, while detector alignment and spatial linearity correction are crucial for ensuring that the imaging system is accurately configured and functioning properly, they do not directly address the uniformity of the image quality across the field. Contrast enhancement pertains to improving the visibility of different structures within an image, but again, this is not the main function of correction tables. Thus, uniformity correction stands out as the vital purpose of correction tables in
