Final answer:
A digital fluoroscopy system with a charge coupled device offers a lower patient dose and higher light sensitivity compared to traditional fluoroscopy. CCDs improve image quality while reducing the need for high radiation doses, enhancing patient safety in diagnostic imaging. Therefore, the correct answer is option 1. patient dose, light sensitivity
Step-by-step explanation:
A digital fluoroscopy with a charge coupled device (CCD) has lower patient dose and higher light sensitivity than conventional fluoroscopy. The correct answer is option 1: patient dose, light sensitivity.
This is because CCDs are very efficient in converting light into electronic signals which means that less radiation is needed to produce a clear image compared to the film-based systems of traditional fluoroscopy. Digital fluoroscopy systems with CCD detectors can provide high-quality images at significantly lower radiation doses to the patient.
Charge-coupled devices use pixels to detect light and record images electronically. Since they are able to capture and process images with high sensitivity to light, they require less radiation exposure to the patient to obtain the necessary diagnostic information.
As a result, the detective quantum efficiency (DQE) is also higher in systems using CCDs compared to conventional fluoroscopy, leading to better image quality with less radiation. This higher DQE is one of the benefits of using modern digital imaging technologies in medicine.
It's important to recognize that all forms of medical imaging using radiation, including digital fluoroscopy, are bounded by the principles of risk versus benefit.
While the patient dose from these diagnostic procedures is generally low and justifiable by the medical information obtained, always striving for lower radiation doses is key to patient safety. The advancement of digital imaging technologies, such as CCDs in fluoroscopy, has been a vital development in reducing patient exposure to radiation.
Therefore, the correct answer is option 1. patient dose, light sensitivity
