Our Spot Markers are 1″ in diameter by 0.25″ and made of clear acrylic. The activity is supplied as a nominal value of ±15%. NIST traceable calibrations with accuracies of ±5% are available. A wooden storage box is also available (upon request).
If the activities above do not meet your specific requirements, give Capintec a call; other activities are available upon request.
“L” and “R” Spot Markers
In order to better mark the orientation of the patient, these spot markers containing 100 µCi of Co-57 identify the Left side and/or the Right side of the patient. The “L” and “R” are clearly identified on the patients film.
The Capintec Rigid Ruler is a plastic tube 0.197″ (5.0 mm) in diameter, containing 15 sequential 0.394″ (10.0 mm) sections of Co-57 and inactive lead. The overall length of the ruler is 6.7″ (17 cm) with an active length of 5.91″ (15.0 cm). Contained activity is supplied as a nominal value ±15%. The standard Capintec Rigid Ruler contains 140 µCi (0.74 MBq) of Co-57. Other activities are available upon request.
The Penpoint Marker is used in tracing the outlines of anatomical features on a patient. The trace appears almost instantly on the gamma camera display. Capintec’s Penpoint Markers contain 100 µCi of Co-57 in a bead at the end of an anodized aluminum rod. The pen-shaped rod screws into a brass cap which shields the active point.
Flexible Markers are useful in outlining anatomical parts or borders of organs on patients. Co-57 is uniformly dispersed in an epoxy matrix and contained in a 2.4 mm flexible plastic tube. The overall and active length of the marker is 19.7″ (50 cm).
The Capintec Flexible Ruler is a plastic tube 0.19″ (4.8 mm) in diameter, containing 45 sequential 0.394″ (10.0 mm) sections of Co-57 and inactive lead. The overall length of the ruler is 18.5″ (47 cm), with an active length of 17.7″ (45 cm). Contained activity is supplied as a nominal value ±15%. The standard Capintec Flexible Ruler contains 20 µCi (0.74 MBq) of Co-57.
Other activities are available upon request.
