Medical imaging Calibration sources

PET calibration sources

ERS manufactures quality assurance sources that are compatible with the leading PET OEM manufacturers to provide high-quality products and customer satisfaction. For the calibration of PET, PET/CT, PET/MR & SPECT systems, 68Ge, 22Na, 57Co and 153Gd sources are used in different forms and activities depending on the system model. Customized sources in different forms and activities can be offered upon customer request by ERS.

FLOOD SOURCEs

Co-57 flood sources are intented to produce uniform radiation fıeld across the camera’s usable field of view with the method’s of NEMA NU-1-2007 to evaluate the gama camera uniformity.

Manufacturer specific sources

ERS manufactures quality assurance sources that are compatible with the leading PET & SPECT OEM manufacturers to provide high-quality products and customer satisfaction. For the calibration of PET, PET/CT, PET/MR & SPECT systems, 68Ge, 22Na, 57Co and 153Gd sources are used in different forms and activities depending on the system model.

Dose Calibrator sources

ERS dose calibrator reference sources are calibrated by direct comparison of standardized solutions traceable to the National Institute of Standards and Technology (NIST), in an identical geometry, using a pressurized ion chamber with ±%5 accuracy. Dose Calibrator sources are manufactured by adding 20 ml activity of epoxy composition in 30 ml volumed of polyethelen vial. Each dose calibrator source has its own colored-coded epoxy.

Cobalt-57, Cobalt-60, Cesium-137, Barium-133 dose calibrator reference sources can be supplied in set or individually in accordance with customer request.

SPOT markers

ERS spot markers are used for a range of purposes including patient orientation during a camera study, gamma camera calibration and quality control, gamma probe and Nal detectors calibration and performance check.

Epoxy marked active area is located in the center of the spot marker with a spherical
diameter of 1 mm (0.039”) and 1.8 mm (0.071”). Overall dimensions of ERS spot markers are 25.4 mm x 6.35 mm (1” x 0.25”)

Rod SOurces

ERS rod sources are calibrated by direct comparison of standardized solutions traceable to the National lnstitute of Standards and Technology (NIST), in an identical geometry, using a pressurized ion chamber with ±5% accuracy.

Pen Point Markers

ERS Pen Point Markers are calibrated by direct comparison of standardized solutions traceable to the National lnstitute of Standards and Technology (NIST), in an identical geometry, using a pressurized ion chamber with ±5% accuracy.
