- X-rays are still used to identify tumours [tumour: An abnormal growth of cells, often caused by cancer.] . X-rays are also used in CAT scans. ‘CAT’ stands for Computer Axial Tomography and generates a three-dimensional image from a large series of two-dimensional X-ray images.hese appear black on X-ray images. X-ray of a pinned wrist fracture. X-rays give more reliable results than ultrasound [ultrasound: High frequency sound, above 20 kHz, that is too high-pitched to hear.] when checking for broken bones and so X-rays are used more often to check for breaks.

- Purpose. A chest X-ray, or CXR, is an image taken of the chest that is used to diagnose various medical conditions. X-rays of the chest use radiation to generate images of the body and can help to determine if there is an infection of the chest wall, thorax, or parts of the thoracic cavity like the heart and lungs.This is the most common way to determine whether or not an infection is present inside the chest.-rays of the chest use radiation to generate images of the body and can help to determine if there is an infection of the chest wall, thorax, or parts of the thoracic cavity like the heart and lungs.

- Blu-ray, also known as Blu-ray Disc (BD) is the name of a new optical disc format that is rapidly replacing DVD. The name Blu-ray is derived from the underlying technology, which utilizes a blue-violet laser to read and write data. The name is a combination of Blue (blue-violet laser) and Ray (optical ray).

- Compensating filters are used to even out the density (darkness) of the radiograph (X-ray image) when you are examining body parts with great variation in thickness. The compensating filter is usually placed between the patient and the X-ray tube (source of X-rays) or collimator (beam-limiting device).

- 4.0 Assign a numerical criticality ranking to each task, as per the steps below. We used a spreadsheet similar to the sample below to track the tasks and to sort by criticality. 4.1 Criticality is the product of the likelihood that a task will go wrong and the consequences of that task going wrong. Therefore, Criticality score = Likelihood score x Consequences score. 4.2 Likelihood is calculated base on two factors, the complexity of a task and the probability of failure. Refer to the charts on the next page for a sample. For a given task, assign a rating in both the complexity and probability columns.

What Is a Skeletal X-Ray? X-rays are waves of electromagnetic radiation that are absorbed differently by different tissues. Bones absorb them well because they are dense. A skeletal X-ray specifically looks at your skeleton—which is made up of all the bones in your body. Skeletons protect our internal organs and allow us to move around.

- Introduction. A DEXA scan is a special type of X-ray that measures bone mineral density (BMD). DEXA stands for dual energy X-ray absorptiometry. This type of scan is also often known as DXA, or dual X-ray absorptiometry.It's also sometimes referred to as a bone density scan or a bone densitometry scan. DEXA scan is a special type of X-ray that measures bone mineral density (BMD). DEXA stands for dual energy X-ray absorptiometry.

Stereotactic Breast Biopsy Image-guided biopsy is performed by taking samples of an abnormality under some form of guidance such as ultrasound, MRI or mammographic guidance. In stereotactic breast biopsy, a special mammography machine uses x-rays to help guide the radiologist's biopsy equipment to the site of the abnormal growth.

How much can a Blu-ray Disc hold? Blu-ray, also known as Blu-ray Disc (BD) is the name of a new optical disc format that is rapidly replacing DVD. The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data.

- Blu-ray Defined. Blu-ray is a high-definition optical disc format. By using a blue-violet laser, as opposed to the standard red laser to read and record data, Blu-ray allows for the storage of high-definition video and large amounts of data.tandard DVDs are recorded and read using a 650nm red laser. Blu-ray uses a 405nm blue-violet laser. This shorter wavelength allows the laser to be focused with more precision, which allows more data to be packed in the same space.

Blu-ray Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format. It was designed to supersede the DVD format, in that it is capable of storing high-definition (720p and 1080p) and ultra high-definition video resolution (2160p).

The Electromagnetic Spectrum X-rays (often written x-rays or xrays) are a type of electromagnetic (EM) radiation. The term X-ray is shorthand for X-radiation, so named simply because it was an unknown form of radiation when discovered. Its discoverer was Wilhelm Röntgen, which is why X-rays are sometimes called Röntgen rays in other parts of the world.

- Dual X-ray absorptiometry (DXA) is the preferred technique for measuring bone mineral density (BMD). DXA has also been called dual energy X-ray absorptiometry, or DEXA. DXA is relatively easy to perform and the amount of radiation exposure is low.

- Spinal X-Ray. X-rays are a form of radiation, like light or radio waves, that are focused into a beam, much like a flashlight beam. X-rays can pass through most objects, including the human body. X-rays make a picture by striking a detector that either exposes a film or sends the picture to a computer.pinal X-rays are pictures of the spine. They may be taken to find injuries or diseases that affect the discs or joints in your spine. These problems may include spinal fractures, infections, dislocations, tumors, bone spurs, or disc disease.
