Item 70003:  Source Holder for Cesium Remote Afterloading: Has a 7.1 mm diameter opening. This insert is used with LDR remote afterloading treatment systems.  There is no spacer because the afterloading system positions the sources.  This insert can also be used with cobalt sources used in some LDR remote afterloading treatment systems.

Item 70008 HDR ¹⁹²IR Quality Assurance Tool Insert Performs the following crucial tests:
•  Source positioning verification to 0.3 mm
•  Timer accuracy
•  Consistency of source activity

The benefits are:
•  Fast, 10-15 minute procedure
•  No films and development procedures
•  No multiple distance estimates

This tool tightly collimates the radiation received by the HDR 1000 Plus to a narrow plane. Three short measurements are taken as the ¹⁹²IR source is advanced to the 4 mm opening.

Item 70009 Source Holder for LDR ¹⁹²Ir Ribbon Seeds: Has a 3 mm diameter acrylic tube which extends from the top of the insert to the most active area of the chamber.  It makes one loop at the active area and extends back to the top of the insert. A collective calibration of the entire ribbon of seeds is obtained. Fourteen iridium seeds spaced one centimeter center to center can fit into the active area.

Item 70010 Source Holder for High Dose Rate Iridium: Has a 2.2 mm opening for the catheter.  A rubber o-ring secures the catheter with a uniform constricting pressure to prevent any movement of the catheter.

The calibration procedure is easy and uncomplicated. The time required for calibration is only a fraction of that required for thimble ion chamber techniques.

Item 70016 Source Holder for Single Seed Measurements: This insert has a 1.2 mm inner diameter Teflon^® tube which positions an individual iodine, palladium, iridium, or gold seed at the most sensitive area of the HDR 1000 Plus.   The Teflon tube allows for easy removal of the seed.

The source holder can be calibrated for several iodine and palladium isotopes at the University of Wisconsin ADCL.  Only one source holder needs to be purchased for these multiple calibrations.

Item 70020 Source Holder for Cesium: Has a 5 mm diameter opening and is commonly used with manually loaded cesium sources.  A spacer within the source holder positions the cesium insert at the most active area of the chamber.  The spacer for positioning the cesium source is removable so that the insert can also be used with some longer cesium sources, and with larger HDR ¹⁹²IR catheters.

Item 70022 Source Holder for Measurement of Iridium Wire Coils:  The iridium wire coil is placed in the tube and uniformly compressed to 2 mm for measurement at the most sensitive point of the HDR 1000 Plus.  This consistent positioning provides for excellent measurement reproducibility. Short term reproducibility is 0.6%.  Linearity over a range of 124 to 2036 MBq is better than 0.1%.

Item 70022:  Source Holder for Seed Batch Assay: Provides multiple seed measurements for up to 500 of the iodine or palladium seeds typically used for prostate cancer treatment.

This source holder positions seeds at the most sensitive area of the HDR 1000 Plus. If you have Source Holder 70016 with an ADCL calibration for the isotope being measured, you may use that calibration in conjunction with Source Holder 70022.

Self absorption resulting from a large number of seeds being placed in the insert is significant. Because of this self absorption, correction factors must be experimentally obtained for each type of LDR seed used. This method is described in detail in Med. Phys. 22 (9) Sept. 1995. Note: a correction factor for iodine and palladium as shown in Fig. 2 of this article, should be determined for each individual well chamber upon receipt of the chamber.

Item 70024 Source Holder for Measurements of Loaded Mick™ Magazine Cartridges:

• QA measurements for dose verification
• No rotational dependence
• Fast measurements
• Iodine or palladium seeds

The Mick™ Magazine Source Holder for the HDR 1000 Plus provides a quick and convenient QA measurement of loaded MICK™ Magazine Cartridges. This Source Holder positions the seeds at the center of the well chamber for quick, reproducible measurements.

Item 70025 One Inch Lead Shielding Ring: This Shielding Ring is made of 1”thick lead to surround the HDR 1000 Plus.  It is constructed of 4 interlocking rings to shield the user during measurement.

Item 70026 Source Holder for Measurement of Metastron™ (Strontium-89 Chloride Injection Samarium-153): Provides a quick and convenient QA measurement of Metastron vials. Source Holder 70026 for 5 cc and 10 cc Metastron Syringes includes one set of two syringe holders, one for a 5 cc syringe and one for a 10 cc syringe.

Item 70023 Source Holder for I-125 Rapid Strand™: 

• A fast and convenient method of performing a quality assurance measurement of your I-125 Rapid Strand™
• The sterile insert maintains sterility of  the I-125 Rapid Strand™
• QA measurements within ± 5% of calibrated IMC6711 I-125 Seeds™
• Short term precision is £ 1%
• No measurable rotational dependence
• The complete calibration system is lightweight and easily portable for use in a sterile environment

The I-125 Rapid Strand™ Source Holder simultaneously measures five seeds at one end of the I-125 Rapid Strand™ while the I-125 Rapid Strand™ remains in the spacing jig. Invert the jig to measure the five seeds at the other end. The source holder itself can be sterilized.

To determine the activity of the I-125 Rapid Strand™, we provide a correction factor derived from an extensive evaluation of the HDR 1000 Plus and Source Holder 70023 containing an I-125 Rapid Strand™ with 10 seeds. Following the evaluation, individual seeds were cut from the I-125 Rapid Strand™ and individually calibrated.  These measurements were compared to the initial, collective seed measurement of the intact I-125 Rapid Strand™ in Source Holder 70023, and the correction factor calculated.

Item 70032 Source Holder for Bard^® Express Seeding Cartridge:

• Quality Assurance measurements within 5% of calibrated seeds
• Measurement reproducibility better than 1%
• No rotational dependence
• A quick calculation provides the average seed activity

The Bard^® Source Holder positions loaded cartridges at the most sensitive position of the HDR 1000 Plus, providing a check of the relative activity of the seed held within the cartridge. The source holder accommodates Bard® Seeding Cartridges with 2 to 6 seeds and can be gas or steam sterilized.
