Medical Dosimetrist

Location: Washington, DC
Date Posted: 07-18-2018
BASIC FUNCTION:
The Medical Dosimetrist determines how much radiation is delivered to a tumor site.  Under the supervision of a medical physicist, the Medical Dosimetrist calculates and generates radiation dose
Distributions in accordance with the treatment plan developed by the radiation oncologist; and uses
Knowledge of physics, anatomy and radiobiology to design optimal treatments that apply an effective dose to the targeted area while sparing normal tissue that surrounds the treatment site.
 
DIMENSIONS:
Indeterminate.
 
NATURE AND SCOPE:
Interacts with staff, physicians, patients and their families, other healthcare providers, Hospital and University officials, and the public.
 
PRINCIPAL ACCOUNTABILITIES:
Designs a treatment plan by means of computer and/or manual computation that will deliver a prescribed radiation dose and field placement technique in accordance with the Radiation Oncologist’s prescription to a defined tumor volume.
 
Consider dose-limiting structures in the design of treatment plans and documents dose in accordance with the Radiation Oncologist’s prescription.
 
Coordinates treatment simulations and tumor localization on dedicated devices, including CT, MRI, and
PET when indicated, for radiation oncology treatment planning.
 
Performs, or assists in the planning of the fabrication of compensation filters, custom shields, wedges, and other beam modifying devices.
 
Performs, or assists in the planning of the production of moulds, casts, and other immobilization devices.
 
Oversees therapists staff in the implementation of the treatment plan including the correct use of immobilization devices, compensators, wedges, field arrangement, and other treatment variables.
 
Performs calculations for the accurate delivery of the Radiation Oncologist’s prescribed dose, documents all pertinent information in the patient record, and verifies the mathematical accuracy of all calculations using a system established by the Medical Physicist.
 
Provides physics and technical support to the Medical Physicist, in radiation protection, qualitative machine calibrations, and quality assurance of the radiation oncology equipment.
 
Oversees, performs, or assists in the application of specific methods of dosimetry including ion chamber, Thermoluminescent (TLD),  or film measurement as directed by the Medical Physicist.
 
Assists in Intracavitary and Interstitial Brachtherapy procedures and in the subsequent manual an/or computer calculation of the dose distributions of these treatments.
 
Teachers applied aspects of medical dosimetry to students and residents, as assigned.
 
Participates in clinical research for the development and implementation of new techniques.
 
Participates in continuing education in the area of current treatment planning techniques, and advances in medical dosimetry.
 
Promotes adherence to the Health Sciences Compliance Program, the Howard University Code of Ethics and the Health Sciences Standard of Conduct.
 
Attends annual and periodic mandatory Compliance Program training including the Health Insurance Portability and Accountability Act (HIPAA) Privacy training.
 
Participates in activities that promote adherence to federal healthcare program requirements.
 
Actively participates in Health Sciences Compliance Program activities.
 
Adheres to the requirements of the HIPAA Privacy Policies and Procedures.
 
Maintains confidentiality of patients, families, and staff.
 
Assumes other duties and responsibilities that are related and appropriate to the position and area.  The above responsibilities are a general description of the level and nature of the work assigned to this classification and are not to be considered as all-inclusive.
 
CORE COMPETENCIES:
Knowledge of the technical aspects of radiation oncology and medical physics to derive computerized treatment plans, and communicate these aspects to the Radiation Oncologist for plan approval, and to the Radiation Therapist for plan implementation.
 
Knowledge of Medical Dosimetrist policies and procedures in order to produce and present treatment plans.  
 
Ability to perform routine duties independent of supervision, but consults with the Radiation Oncologist and Medical Physicist as required.
 
Ability to operate and perform quality assurance, under the direction of the Medical Physicist, on the treatment planning computer.
 
Working knowledge of radiation safety and current rules and regulations of the Nuclear Regulatory Commission. 
 
Ability to interpret and execute treatment plans as defined in relevant treatment protocols.
 
Possesses mathematical skills including algebra, trigonometry, and introductory calculus and must be able to visualize objects in three-dimensional concepts to facilitate the treatment planning process.
 
Ability to develop and evaluate methodologies, equipment and staff operations.
 
Ability to produce patient contours using CT scans and MR images.
 
Ability to calculate and review patient treatment charts for accuracy of calculations.
 
Ability to work with ionizing radiation requiring observance of radiation safety procedures.
 
Demonstrated leadership skills, including the ability to oversee and coordinate dosimetry workflow, prioritize tasks, audit work quality, orient and train radiation therapy students and implement new dosimetry procedures with minimal direction.
 
General knowledge of anatomy and physiology.  Understands physics and dosimetry principles of external beam radiotherapy and Brachytherapy.
 
Knowledge of radiation therapy equipment, such as linear accelerators, radiation therapy simulator and CT simulator.  Understands the working principles of dose measurement instrument and detectors such as diodes, ionization chambers, TLDs and film dosimetry.
 
Competence in both oral and written English.
 
Ability to establish and maintain effective and harmonious work relationships with staff, physicians, Hospital and University officials, and the general public.
 
CARES CRITERIA:
Must demonstrate collaboration; accountability; respect; excellence; and service.
