What occurs when using an AEC system for a hypersthenic patient?

When utilizing an Automatic Exposure Control (AEC) system for a hypersthenic patient, the correct consideration is that there will be decreased exposure time. Hypersthenic patients have a higher body mass and thicker body habitus, which can create challenges in imaging due to the need to penetrate denser tissues.

The AEC system operates by measuring the radiation reaching the image receptor, automatically adjusting the exposure time to achieve optimal image quality. In the case of a hypersthenic patient, the AEC may shorten the exposure time in order to prevent excessive radiation exposure while still obtaining a diagnostic-quality image. This allows for rapid imaging while catering to the unique challenges presented by the higher density of such patients.

Other factors like increased kVp or decreased image contrast may not specifically apply to AEC adjustments for hypersthenic patients, as the AEC primarily works to optimize exposure time to accommodate the patient’s larger size without compromising image quality. Increased receptor exposure could also misrepresent the situation, as the AEC does not necessarily increase exposure, but optimizes it for the conditions of the patient.
