Our Mission

To provide the highest quality medical physics services to the radiation community in the pursuit of better patient care.

We believe that our knowledge, training and experience should aid the Physician in developing and delivering the best treatment plan possible for the patient.

Company Profile

Physics Services Incorporated (PSI) was founded in 1989 to provide the Radiation Oncology community with the needed physics support required by the New York State Department of Health and national quality assurance standards. Physics Services Incorporated was founded by James P. Vaughan MSc., an ABR certified medical physicist with over twenty five years experience in the field. Physics Services Incorporated has been performing medical physics services for the Radiation Oncology community for over 20 years and provides these services to numerous Radiation Therapy clinics throughout New York State and Pennsylvania. The company was Incorporated in 1994 and is a privately held New York Corporation.

Our primary focus is in the area of Radiation Therapy, where we provide consultations for room shielding, equipment purchases, equipment installation, acceptance testing and most important ongoing weekly quality assurance. This applies to all models of linear accelerators, simulators and treatment planning computers. Our list of manufacturers include Varian, Philips, Siemens, Mitsubishi, Cascade, Toshiba and a lengthy list of treatment planning systems, including CMS Xio, Varian Eclipse and VariSeed for seed implants.

We own and operate a centralized Dosimetry facility which houses our bank of CMS Xio treatment planning systems and remote access FOCAL simulation/review stations. This allows physicians and clinics to access patient planning (3D and IMRT) without the additional cost of personnel and equipment.

Our Rapid IMRT Plan (RIP) allows any clinic with any accelerator to be up and running with IMRT in less than one month. We can provide the solutions to allow your patients to receive the state-of-the-art treatments at a fraction of the cost.

We provide these services and quality assurance programs for both small and large radiation therapy departments and have the full complement of measuring equipment available so that your institution does not need to provide any major equipment for the routine quality assurance. We are also able to provide different levels of service for the different needs of each clinic; from full-time staffing and dosimetry services to part-time weekly, monthly and annual quality assurance visits.

Our staff has over 120 years combined experience in medical physics and all possess professional degrees in the field. All work is overseen by an American Board of Radiology certified Physicists, as required by the New York State Department of Health. We are fully licensed and insured and carry our own malpractice coverage. We are always available for all types of medical physics needs, including brachytherapy, diagnostic x-ray shielding design, x-ray equipment acceptance and inspection, nuclear medicine and dental x-ray needs.
