Additional Services at Medical Radiation Physics


Purchasing the proper accelerator can be complicated. Our physicists can assist you in determining that the accelerator you have chosen meets the manufacturer’s performance specifications. Medical Radiation Physics will be happy to consult with you when you finalize your purchase agreement to ensure that the performance standards necessary to deliver the most clinically challenging treatments have been included. We are flexible and will work independently or with your staff as desired.

Shield Calculations and Shielding Verification

The time to learn about shielding requirements of local and federal regulations and guidelines is BEFORE your linear accelerator vault is built and the linac has been installed.  Unfortunately, many times the installation occurs without consideration of these regulations, resulting in costly alterations after installation. MRP specializes in providing shielding calculations necessary to ensure that your vault will provide the required protection for patients, personnel, and the public. We will perform the radiation safety survey, and prepare a detailed report. We are flexible and will work independently or with your staff.

Beam Modeling

To plan patient treatments, your treatment planning computer requires a beam model for each accelerator beam. We make the required accelerator measurements and create the beam models for you. If the data is not measured correctly or if it is not modeled correctly, your treatment planning computer will not accurately predict patient dose.

Some of the most catastrophic patient dose errors have been the direct result of incorrect modeling.

Project Consultation

Whether building a new department or just replacing an old machine, your Radiation Oncology department is important to us. Some of the most expensive mistakes made in radiation oncology are made on the drawing board and in the planning phase. MRP will help you avoid costly design errors. For example, physician proximity to the accelerator was not an important design feature in the past. But today’s use of image guidance requires physician participation at the accelerator console multiple times each day. MRP can ensure that your facility design will meet the needs of today’s clinical practice. Our team’s flexibility allows us to work independently or with your staff as needed.

Implementation of New Technologies

We can assist your physicians, physicists, and staff with the following: VMAT™/Rapid ARC™, IMRT/IGRT, and Stereotactic Radiosurgery.

Annual Linac Inspection and Calibration Utilizing TG-142

Since TG-142 replaced TG-40 as the guideline for quality assurance of medical accelerators, physicists have attempted to update their quality assurance programs to adopt these recommendations.  With the advent of IMRT, SBRT, IGRT and Respiratory Gating, imaging specifications have been introduced, mechanical tolerances have become smaller, and beam specifications have become tighter.  Newer accelerators require a considerable amount of oversight compared to their predecessors.  Let us assist you with your annual QA to implement these current standards of practice.

HDR Programs including all PBI applications commercially available

Our team has vast experience in treatment planning and delivery of partial breast high dose rate brachytherapy.  These PBI techniques include utilizing SAVI®, Contura®, and Mammosite® Multi-Lumen™ applicators.  We can assist your facility in implementing a new program or provide staff to maintain 
an existing system.

4D based treatment planning coupled with 4D daily CBCT for stereotactic lung patients

MRP also has expertise in 4-D image guided based adaptive stereotactic body radiotherapy for thoracic cancers.  One such system utilizes both 4D CT simulation techniques combined with 4D Conebeam CT for daily treatment delivery verification.

The system also utilizes a dual registration technique that allows the patient to be aligned first to their bony anatomy, and then to the time weighted average position of the tumor in the 10 phases of respiration.

Our team is not limited to the 4D approach to treating SBRT lung.  We have expertise in several other techniques of planning and delivery.

MONACO® treatment planning with VMAT™ treatment delivery

MONACO®(ELEKTA CMS software) is a Monte Carlo based treatment planning system for production of IMRT and VMAT™ treatment plans. ELEKTA CMS software™completes the beam model for the customer, using beam data measured and supplied by the customer.  MRP has measured and supplied the required data for multiple customers.  In addition, MRP has commissioned multiple MONACO® workstations for both IMRT and VMAT™ treatment delivery.
