The study demonstrated that computer analysis of mammograms can provide a substantial and statistically significant increase in radiologist screening efficacy.
We report catheterization laboratory personnel dose per case during parallel use of two laboratories from different manufacturers. Initially, four working positions were monitored. Review of the data from the first 140 cases showed a wide range of dose per case. Measurements were then limited to diagnostic coronary angiography cases in which a cardiology fellow was the primary operator. On a per case basis, the dose was higher when a fellow was in the laboratory with pulsed progressive fluoroscopy or was in fellowship year one. The increased dose for first year fellows was more related to increased fluoroscopy time than to cine angiography time. This study emphasizes the importance of close supervision of cardiology fellows early in their training to limit dose to patients and personnel, and it underlines the importance of each catheterization laboratory routinely having the actual personnel dose per case measured.
Serum levels of propylthiouracil were measured in 8 normal persons and in 7 patients with hyperthyroidism after a single, 300 mg, oral dose of 6-n-propyl-2-thiouracil (PTU). The patients with hyperthyroidism were restudied after 3, 6, and 9 weeks of individualized treatment with PTU. The serum half-life of the drug in normal subjects was 1.65 h. In patients with hyperthyroidism the serum half-life was similar, and it did not change significantly as the euthyroid state was achieved.
Purpose: This paper describes systematic choices and their rationale for structuring a curriculum for a Radiation Oncology Physics Residency accreditable by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP). Method and Materials: The AAPM Report No. 90, “Essentials and Guidelines for Hospital‐based Medical Physics Residency Training Programs” lists ten rotation topics related to routine clinical treatment planning and delivery procedures and processes and the technical support and quality assurance that support them. The procedures implemented in a specific radiotherapy department depend upon the equipment and software purchased by the facility as well as the individual preferences of the radiation oncologists and staff of the department. Specific procedures and processes appropriate for the rotation categories were identified and listed. However, an approach to developing a Resident's competency performing the processes can be generalized into three phases. In Phase I the Resident observes a Mentor carry out the process and reads background material. In Phase II the Resident carries out the process under close supervision by the Mentor. In Phase III the Resident carries out the process independently. The Mentor documents satisfactory completion of each phase. The Assessment of the Resident's competency is completed by oral examinations by the Residency Program Faculty. Results: The approach was applied to writing a Self‐Study Document for CAMPEP. The document contained a detailed description of ten competency‐based rotations using the three phase format. The descriptions of the rotations composed the majority of the 233‐page study. Conclusion: A Radiation Oncology Physics Residency Program can be systematically constructed by identifying processes and procedures associated with AAPM Report No. 90 competencies and then developing the Resident's competencies with these processes and procedures in three phases.
