Which device could be used to view a patient's internal organs?

An ingestible camera is specifically designed to capture images from within the gastrointestinal tract as it travels through the digestive system. This technology allows for direct visualization of internal organs, particularly the esophagus, stomach, and intestines, providing valuable diagnostic information without the need for invasive procedures.

While other devices like CT scanners, ultrasound machines, and X-ray machines are commonly used for imaging various parts of the body, their operation principles and the area of focus differ significantly. For example, CT scanners provide cross-sectional images and are effective for viewing structures in three dimensions, but they require external scanning rather than direct visualization from inside the body. Ultrasound machines are great for real-time imaging of soft tissues and organs, yet they are limited in terms of depth of penetration and specific body areas. X-ray machines are excellent for viewing bones and certain other structures, but they do not provide the internal details in the same way that an ingestible camera does.

Therefore, the ingestible camera stands out as the most suitable device for directly viewing a patient’s internal organs in the gastrointestinal tract.
