A step by step visual guide to using the Sectra Visualization Table for 1st and 2nd year medical students

Abstract

INTRODUCTIONThe Sectra Visualization Table (SVT) is a computer that allows a user to view CT and MRI imaging rendered in 3D, which can be rendered in a tissue specific manner and manipulated using a touch screen for educational and clinical purposes. SVT is an extremely useful medium, but unclear how long it takes for a novice operator to become proficient. The objective of this study was to develop a training document which includes strong visual cues for efficient processing of the SVT's use while addressing andragogical methods.METHODSLiterature search was conducted regarding SVT and 1st year medical student (MS) curriculum. 60 MS were given 15 minutes to read the guide composed of illustrations with minimal text. Guide included step by step demonstrations of tools, used to manipulate the CT/MRI image. Subsequently, they were allowed to manipulate images with the touch screen. Their proficiency of manipulating 3‐D images was assessed. Likert Scale questionnaire was administered post test.RESULTSNo obvious studies were identified regarding the use of SVT with MS. MS successfully interpreted the guide, and used the tools associated with manipulating images. The Likert Scale scores were positive regarding aiding the MS in understanding stereostructural anatomy.DISCUSSIONFollowing an anatomy dissection or didactic course, having access to manipulate 3‐D CT/MRI images would enhance MS’ understanding of stereostructural anatomy. MS will be exposed to their patients' imaging anatomy. SVT guide proved to be a shallow learning curve for students rotate and magnify an actual CT/MRI on a 46 inch touch screen.CONCLUSIONThis study revealed that a visual heavy teaching guide can enable MS to manipulate 3D CT/MRI images with minimal training.
