Pixel Calibration Phantom




• Designed to make pixel size calibration easy and accurate
• Pixel calibration is an essential component of a SPECT quality control program
• Ideal for verifying pixel size stated by camera manufacturer at acceptance testing and as part of a quality control program
• The attenuation correction algorithm uses the pixel dimension, and if in error, the images will be either over or under-corrected

Pixel calibrations should be made for:
• All acquisition matrices used, and in both the “x” and “y” axis
• All zooms clinically used

Verifying pixel size is critical if:
• SPECT imaging is to be performed
• Linear distances or lesion sizes are to be stated in clinical reports
• Quantitative procedures are to be performed (such as quantitative gated cardiac studies)

Specifications
The phantom has seven source locations, with the distance between source locations accurately determined. These distances range from 70 to 440 mm. Two lead source holders, each with a 1.5 mm hole located in the center, are included with the phantom
Dimensions: 4 (w) x 20 in (d) (10.2 x 50.8 cm)
Weight: 2.54 lb (1.15 kg)
