Computed Tomography

Computed tomography (CT) technology has been at the forefront of medical imaging for almost 40 years. Since its discovery and acceptance into clinical practice in the early 1970's CT has helped to save countless lives and improve the outcomes of millions of patients.

As a practicing CT technologist for more than two decades, I am deeply committed to the advancement of the modality and to the education of tomorrow's CT imaging professional. As CT technology progresses, many of the decisions controlling image quality, diagnostic success, and patient dose are dictated by the protocol selected by the technologist. A protocol-driven CT exam often fails to take into account the inherent nuances of an individual patient's symptomology and disease etiology. The fully-competent CT technologist must have the ability to identify and apply the accepted gold-standards in imaging parameters to extend beyond the basic protocol. By individually tailoring a CT examination, the competent technologist efficiently acquires the appropriate images, during the appropriate phases of contrast enhancement, and with an absolute minimum of patient dose. My work in CT education strives to provide technologists with current resources to improve their clinical practice. Upholding the highest standards in CT exam design results in improved patient outcomes and reduction in exposure to unnecessary ionizing radiation.

CT Education & Credentialing

As a modality that utilizes ionizing radiation, only credentialed Radiologic Technologists may choose to specialize in the practice of CT. Technologists may also be required to attain an additional credential from the American Registry of Radiologic Technologists (ARRT) in CT. This advanced-level credential is obtained by passing the standardized examination in CT offerred by the ARRT.

In an effort to assist technologists in their preparation for this exam, I have published two review texts. The first was written in 1996 and has become a leading resource in CT exam preparation, selling nearly 20,000 copies:

In the spring of 2008 I began work on an expanded and updated version of this review text. Published in May of 2010, Mosby's Exam Review for Computed Tomography contains the most-up-to-date information on the physics and clinical appications of CT including advanced concepts such as cardiac CT, PET-CT, and the latest in dose reduction techniques. In addition to three full-length sample tests, the second edition also contains comprehensive review chapters on CT theory, corresponding to the content specifications of the ARRT exam. Students who purchase this edition also receive access to an online component with an additional 635 multiple-choice questions for review and exam simulation.
