Disk & Rod Sources

Disk & Rod Sources

Disk Source
Disk Sources are mainly used for checking the performance of GM tubes and NaI detectors. The disks measure 1" (25.4 mm) by 0.25" (6.35 mm) and are manufactured of high-strength plastic. The active diameter of the disk is 0.197" (5.0 mm) with the active area centered in the disk.

Rod Source
These sources are used for calibrating well type NaI detectors. They are constructed of high- strength plastic to withstand the rigors of constant use in a busy department. They have a flat base which allows easy positioning in the vertical position required for consistent accuracy (in the counting of ) many tests. Rod Sources are calibrated as NIST traceable with an accuracy of ± 5% at the 99% confidence level. Each source consists of a lucite rod measuring 12.7 mm (0.5") x 75 mm (2.95") as a standard size. The active diameter of the rod source is 0.187" (4.75 mm).

Markers & Rulers

 

Markers & Rulers

Spot Markers
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.

Rigid Ruler
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 Rigid Ruler contains 140 μCi (0.74 MBq) of Co-57. Other activities are available upon request.

Penpoint Markers
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. 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 Marker
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).

Flexible Rulers
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 Flexible Ruler contains 20 μCi (0.74 MBq) of Co-57. 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.

 

 
 

Flood Sources

Cobalt-57 Flood Source Phantoms

 

Cobalt-57 Flood Source Phantoms

In today’s market we must look for the best value. That does not necessarily mean the lowest price, but it does mean that the product you buy must meet its expected performance standards while providing a sufficient margin of safety and reliablilty. Most of the present Flood Source manufacturers understand this and have strived to meet this criteria.

We also provide sources for special requirements with transmission sources and as needed special activity amounts for floods.

Full Line of Flood Sources
We have available, circular and rectangular flood phantoms for standard, LFOV, Dual and Triple Head Cameras. Capintec offers FREE disposal of your old floods when you place an order for a new one, relieving you of that concern.

Perflexion Flood Source

 

Perflexion Flood Source

Eckert and Ziegler Isotope Products Perflexion flood source eliminates bulk and weight with its unique tungsten composite shield. Together with the superior uniformity, low impurities and excellent durability, Perflexion makes every other source obsolete.

FEATURES :
• Lightest Weight – weighs less than 29lbs including the tungsten shield and soft case
• Smallest form factor – source rolls to fit in a 6”x6”x22” tube for convenient storage.
• Best Shielding – 5-10k better than leas cases.

Fillable Flood Sources

Designed for More Uniformity Required by SPECT

Fillable Flood Sources

Fillable Flood Sources

Fillable floods are plastic forms with a water-tight central cavity that holds radioactive solution. To increase their accuracy in testing uniformity, these floods are designed for horizontal filling, which prevents the bulging caused by water pressure during vertical filling and ensures greater uniformity of radioactivity distribution. This enhanced uniformity is particularly important when testing SPECT systems.

FEATURES :
• Horizontal filling
• Built-in bubble trap

SPECIFICATIONS :
• Rectangular: cavity 16" (40.6 cm) wide, 21" (53.3 cm) long, 0.5" (1.3 cm) thick, 10 lbs (4.5 kg)
• Jumbo: cavity 17" (43.2 cm) diameter, 0.5" (1.3 cm) thick, 9 lbs (4 kg)
• Gigantic: cavity 22" (55.9 cm) diameter, 0.5" (1.3 cm) thick, 13 lbs (5.6 kg)
