Bill attended Hope College in Holland, Michigan were he earned a B.A. in Physics. After Hope college Dr. Davros became interested in the applied physics of medical imaging and was directed to the emerging field of Medical Physics. He attended the University of Wisconsin-Madison (UW) and received his master degree and doctorate in Medical Physics. Dr. Davros' first job was as a design physicist for Radiation Measurements Incorporated (RMI). Later he went into academic work holding the rank of Assistant professor of radiology at Georgetown University. For 21 years Dr. Davros was at the Cleveland Clinic where he the founded the section of Diagnostic Imaging Physics. The last five years he has been senior member of the section. Dr. Davros retired from Cleveland Clinic in March of in 2014. He joined NPC in September of 2014.

Bob has been a medical physics consultant for over 20 years, and before that he worked in the industry of radiation measurement for 17 years as an engineer, product manager, staff physicist and calibration lab manager. Among his accomplishments is having worked on the development team that designed the first commercially-available digital instrument for noninvasive measurement of X-ray tube kilovoltage. Aside from consulting, Bob is also currently serving as a physicist reviewer for the mammography and MRI accreditation programs of the American College of Radiology. Bob is certified in diagnostic radiologic physics by the American Board of Radiology. Bob has also served on two AAPM committees.
Tommy has a Master of Science degree in Health Physics and over 14 years of experience in the healthcare industry. The majority of that time has been with Charleston Area Medical Center in the field of Nuclear Medicine. He has experience in managing the day-to-day operations of an outpatient PET/CT department including quality assurance, staff and student training, and regulatory compliance. His medical physics consulting experience includes diagnostic radiology, CT, and nuclear medicine.
Kelly has more than 18 years experience in a variety of areas in nuclear medicine and radiation safety. He has over 10 years of clinical experience and has worked in a radiopharmacy for six years.

Yes FINALLY! The ACR has published its Digital mammography QC manual (but you can't start using it until 2017). The site can opt to use the new ACR QC manual or continue to use the manufacturer's manual.
The manual is being provided free of charge to accredited sites by the ACR. For more information visit the ACR website.
NPC endorses the use of the ACR manual, however it would require the site to purchase a new phantom. In some cases, using the new manual would result in less time spent by the technologist on routine QC, and in all cases, the amount of time spent by the physicist on QC would be reduced. NPC will reduce its physicist fees for sites using the new manual. Talk to or Email Bob Kobistek for more information about this.
Just like anybody else, we at NPC like to hear people say good things about us. Are you a happy customer who would like to let us know we did a good job? Or a bad job? Did a particular NPC employee do something that impressed you? If so, please visit our Feedback page and let us know. We’ll publish the good ones below! Read what our customers have to say about us:

Findlay, OhioI've been a customer of NPC for several years and I'd like to compliment the excellent job that they do. NPC goes to great lengths to make sure that my consulting needs are met on a timely basis and I've always been satisfied with both their work and professional demeanor. One aspect of NPC that is of particular use to me is the website. Everything I need to have access to is located online in one convenient place including reports, physicist credentials and any forms that I may need. The NPC website has been very beneficial during inspections! Great job NPC!

Frequently Asked Questions
Accreditation (all modalities)
You should also visit the website of the accrediting body, the American College of Radiology, The Joint Commission, or the Intersocietal Accreditation Commission. For ACR accreditations, you should download the program requirements documents and read them over. There are also clinical imaging guides which you should eventually also read. Be sure to contact your NPC representative early in the process. We need to schedule visits for phantom imaging, and we can help answer your questions along the way.
Direct links to the ACR Program Requirements Documents are as follows:
- As in all mammography installations, everything has to pass before the physicist can provide a report to the ACR. Unlike the annual physicist survey, the testing performed after installation (called a Mammography Equipment Evaluation or MEE) does not allow for the 30 day margin in correcting deficiencies. All deficiencies must be corrected before the unit may be used clinically.
- Be sure all connectivity is enabled. The physicist must not only test the FFDM unit but also the radiologist viewing stations and the printer.
- If remote viewing stations are being installed, be sure arrangements can be made to have the physicist visit the various sites.
- Be sure the physicist has access to all pertinent QC manuals -- from the FFDM manufacturer, the soft copy workstation manufacturer and also from the printer manufacturer. Your physicist may request copies of these manuals in advance of the acceptance test in the event he is not familiar with the particular model.
"A physics survey must be performed on each Gamma Camera or PET unit at least annually." This includes the annual camera QC tests and the annual phantom scans for both routine nuclear medicine and/or PET. All test data must be sent to a qualified medical physicist for review and report preparation. Further, "the qualified practicing medical physicist should meet with the supervising physician and the QC technologist to review the results of the survey and the effectiveness of the technologist QC program, and to recommend any corrective action or repairs that are needed." NPC will be adding signature lines for the physician and the appropriate technologist in our reports to verify that all involved are aware of the test results. For you information" The supervising physician is responsible for assuring compliance with the recommendations of the medical physicist."
Also, the ACR requires semi-annual QC testing with the SPECT/PET phantom. "At this time, the ACR strongly recommends quarterly testing of each system with an appropriate phantom in addition to other tests recommended by the vendor. At a minimum, testing with the appropriate phantom must be performed semi-annually." This requires that the phantom is imaged and evaluated. The evaluation can be by the technologist.
NPC offers programs for either information review and report preparation or on site annual ACR testing. If you would like to change any of your current programs, contact your consultant.
