What detector is used to pick up the x-rays in hospitals?

The detector used to pick up the X-rays in hospitals is called an X-ray detector or an X-ray image intensifier. There are several types of X-ray detectors used in medical imaging, each with its own characteristics and applications. Here are some of the most commonly used X-ray detectors:

1. Fluoroscopy Detectors: These detectors are used in real-time imaging procedures such as fluoroscopy, which is commonly employed during surgeries and interventional procedures. Fluoroscopy detectors are typically flat-panel detectors or image intensifiers that convert X-rays into visible light, which is then displayed on a monitor.

2. Radiography Detectors: These detectors are used to capture static X-ray images for diagnostic purposes. They are commonly known as digital X-ray detectors or flat-panel detectors. Radiography detectors convert X-rays into electrical signals, which are processed and displayed as digital images on a computer screen.

3. Computed Tomography (CT) Detectors: CT scanners utilize rotating X-ray detectors to capture multiple X-ray images from different angles. These detectors are highly sensitive and can detect very small variations in X-ray intensity, allowing for the reconstruction of detailed cross-sectional images of the body.

4. Mammography Detectors: Mammography detectors are specialized X-ray detectors designed for breast imaging. They are highly sensitive and can detect subtle changes in breast tissue density, which is crucial for early detection of breast cancer.

5. Dental X-ray Detectors: Dental X-ray detectors are used in dentistry to capture images of the teeth and jaws. These detectors are typically compact and designed for intraoral and extraoral imaging.

The selection of the specific type of X-ray detector depends on factors such as the imaging modality, required image quality, dose efficiency, and clinical application. Ongoing advancements in detector technology continue to improve the sensitivity, resolution, and speed of X-ray imaging systems, leading to better diagnostic capabilities in healthcare.
