I did answered my question but not sure weather is correct or not
1)How is X-ray produced and why can it be used to help us see the structure inside the body?
X-rays are produced when electrons strike a metal target. The electrons are liberated from the heated filament and accelerated by a high voltage towards the metal target. x-ray are form of electromagnetic radiation that is sent through the body and help us see the structure inside the body
2)Describe the process of X-Ray computerised tomography. What information does this process provide that ordinary X-ray images do not?
Create 3D image so it can provide more information than X-ray image (2D), such as depth of a structure
"Physic" has a totally different meaning, no matter how many c's you put at the end!
this is not the answer for my question,i think nobody knows my question
To verify the correctness of your answers about X-rays, we can compare them with the generally accepted explanations.
1) How is X-ray produced and why can it be used to help us see the structure inside the body?
Your answer is partially correct. X-rays are indeed produced when high-energy electrons collide with a metal target. However, instead of being "liberated from the heated filament," the electrons are released from a heated cathode filament, forming a negatively charged electron cloud. The positively charged anode attracts these electrons, causing them to accelerate towards the metal target.
When the fast-moving electrons strike the metal target, they interact with the atoms in the target material. This interaction causes the electrons to lose energy, resulting in the emission of X-ray photons. These X-ray photons can penetrate the body's tissues to varying degrees depending on their energy. Dense structures such as bones absorb more X-rays than soft tissues, resulting in differential absorption and the formation of an X-ray image.
X-rays can help us see the internal structures of the body because they can pass through soft tissues while being absorbed or scattered by denser structures like bones. This differential absorption allows X-rays to create an image of the body's internal structures, providing valuable diagnostic information to healthcare professionals.
2) Describe the process of X-Ray computerized tomography. What information does this process provide that ordinary X-ray images do not?
Your explanation of CT scanning (X-Ray computerized tomography) producing a 3D image is correct. CT scans use a rotating X-ray machine to capture detailed cross-sectional images of the body. The process involves the following steps:
1. The patient lies on a table that moves through a doughnut-shaped scanner.
2. The X-ray tube and detectors rotate around the patient, capturing multiple X-ray images from different angles.
3. A computer combines these individual images to create a detailed 3D image of the scanned area.
CT scans provide more detailed information compared to ordinary X-ray images due to their ability to capture images from multiple angles. This allows for the reconstruction of a 3D image, providing a clearer visualization of the internal structures and their spatial relationships. This additional information helps in diagnosing and evaluating conditions that may not be easily visible on ordinary X-ray images, such as tumors, internal bleeding, or complex fractures.
