Board Certification: Persons hired or reassigned to TMP positions in the VHA must be board certified in the field of therapeutic medical physics by an approved certifying body. The board certificate must be current and the applicant must abide by the certifying body's requirements for continuing education. Approved Certifying Bodies The American Board of Radiology (ABR) in any of the following field titles: Therapeutic Medical Physics Therapeutic Radiologic or Therapeutic Radiological Physics Radiologic Physics or Radiological Physics The American Board of Medical Physics (ABMP) in the subfield of Radiation Oncology Physics. The Canadian College of Physicists in Medicine (CCPM) in the subfield of Radiation Oncology Physics. Physical Requirements: See VA Directive and Handbook 5019. English Language Proficiency: TMPs must be proficient in spoken and written English as required by 38 U.S.C. 7402(d), and 7407(d). May qualify based on being covered by the Grandfathering Provision as described in the VA Qualification Standard for this occupation (only applicable to current VHA employees who are in this occupation and meet the criteria). Grade Determinations: In addition to the basic requirements for employment, the following criteria must be met when determining the grade of candidates. GS-14 Therapeutic Medical Physicist (Advanced Level) Experience: In addition to the basic requirements, completion of a minimum of 1 year of progressively complex experience equivalent to the next lower grade (GS-13). This would be experience which demonstrates the knowledge, skills, and abilities (listed below) to fully perform at that grade level. GS-13 experience is defined as: Knowledge regarding the safe and efficient use of all radiotherapy devices for external beam radiotherapy. The ability to evaluate and ensure correct and safe operation of radiotherapy equipment through complex problem diagnosis and scheduled quality assurance. Knowledge of the scientific, clinical, and technical applications of high dose rate and low dose rate brachytherapy treatment simulation, planning, dosimetry, and treatment methods. Expertise in the professional, scientific, and technical aspects of shielding methods for external beam radiation delivery systems, radiation survey methods, developing procedures, setting action levels, delivering radiation safety training, developing and documenting competencies, and reporting. This includes an in-depth knowledge of regulatory requirements and guidelines for radiation shielding and personnel protection. Ability to exercise independent professional judgment in the performance and evaluation of calibration, acceptance testing, and clinical commissioning procedures for all types of external beam photon and electron beam delivery systems. Skilled in the evaluation of acceptance testing and commissioning results of CT simulators. Technical skills in 3-D treatment planning, intensity modulated radiation therapy treatment planning, and stereotactic body radiation therapy planning. This includes specialized knowledge of clinical process steps and resource requirements for planning and delivery of radiation oncology treatments. Ability to process information from multi-modality imaging datasets for treatment planning, treatment verification, and radiotherapy response assessment. In addition to the experience above, the candidate must demonstrate the following KSAs: Advanced expertise and experience in the safe and efficient use of all radiotherapy devices for external beam radiotherapy and brachytherapy. Highly developed expertise with commissioning linear accelerators and treatment planning systems for complex clinical use, to include project management, performance testing, data acquisition, beam modeling, and validation testing. Advanced knowledge (treatment simulation, planning, dosimetry, and treatment methods) of the scientific, clinical, and technical applications of one or more specialized procedures including, but not limited to, high dose rate brachytherapy, low dose rate brachytherapy, stereotactic body radiation therapy, stereotactic radiation therapy, intensity modulated radiation therapy, volumetric modulated arc therapy, total body irradiation, advanced image-guided therapy, and adaptive therapy. Advanced expertise in acceptance testing, clinical commissioning, and (when applicable) calibration procedures for a variety of ancillary radiation oncology delivery, imaging, dosimetry, metrology, and computational systems.
