Ray tissues
WebMay 27, 2024 · In medicine, X-rays are used to view images of the bones and other structures in the body. X-rays were first discovered by Wilhelm Conrad Roentgen, a German physics professor. Roentgen also studied X-rays and their ability to pass through human tissues to produce images of the bones and metals visible on developed film. WebThe degree of x-ray attenuation depends on the tissue type. These differences are converted into ‘CT numbers’, better known as Hounsfield units (HU).A spectrum of gray tones is generated, from -1000 to +3000 (note: the upper limit is determined by the scanner type).Tissues with low attenuation (such as air and fat) have a low HU number.

Areas with high levels of calcium (bones and teeth) block the radiation, causing them to appear white on the image. Soft tissues allow the radiation to pass through. They appear gray or black on the image. An X-ray is the fastest and most accessible form of imaging.

In the case of the knee, it will involve the detection of secondary signs such as effusion or soft tissue swelling. Check for an effusion on the horizontal beam lateral: peripatellar fat pads should sit next to each other. anterior suprapatellar fat pad. WebX-ray beam attenuation. As the x-ray beam passes through tissue, photons get absorbed so there is less energy; this is known as attenuation. It turns out that higher energy photons travel through tissue more easily than low-energy photons (i.e. the higher energy photons are less likely to interact with matter).
