    Montana Cancer Specialists
    On February 28, 2017, APQS activated a Rad-X Filter that was purchased and installed by the hospital in an attempt to remediate this specific problem.
    Immediately following the activation of the Rad-X Filter we have had zero call backs in regards to this problem.
    When I estimate Elekta’s “cost of service”, before and after Rad-X Filter activation, the difference is substantial.
    I would recommend this impressive product to any organization trying to lower the incidence of failure, thereby lowering cost of service and improving system availability.

    Even the earliest installed Rad-X Filters are still in use, and at least during my time at Glendale the total benefit to GMH as a result of having the Filters was hundreds of thousands of dollars.
    The electronic components lasted longer with no issues and the x-ray tubes lasted years longer compared to those equipment that did not have the filters.
    I would highly recommend the use of this impressive product to any hospital interested in maintaining a high level of system availability and lowering “need and cost of service” for their high-end medical systems.

    It is interesting to note that even the earliest installed Rad-X Filters are still in use, and have significantly reduced power-related issues to our machines and helped improve uptimes. Glendale Memorial Hospital has not experienced a Rad-X Filter failure and likewise, the Rad-X Filter has not contributed or caused downtime in the Imaging suites. I would highly recommend that Directors of Radiology / Facilities / Biomedical Services consider utilizing the Rad-X Filter in their major equipment areas.

    McLaren Health Care hospitals have never experienced a Rad-X Filter failure and likewise, the Rad-X Filter has never contributed or caused downtime in its Imaging and Therapy suites.
    I would highly recommend this filtration product to any hospital and service organization trying to improve system reliability and uptime,
    especially for situations whereby the equipment is installed within electrical environments that experience frequent power disturbances.
