Medical Imaging – X-Ray Imaging Softwares Market & Contrast Media

we’re going to be looking at Medical Imaging – X-Ray Imaging Softwares Market & Contrast Media which also includes the use of contrast media this is the first clinical x-ray taken showing a hand and the ring on a finger the quality of the image wasn’t very good and it needed an exposure time of 15 minutes as opposed to modern x-ray images which only need an exposure time of about 10 milliseconds and you can see the quality is much improved this image is showing you the hand of a doctor who was

Medical Imaging – X-Ray Imaging Softwares Market & Contrast Media using x-rays early on and hand has skin and bone cancers and that’s due to the overexposure of x-rays well before the dangers were fully understood an x-ray image is a shadow image and how it works is for air because it has a very low density so we say it has a protein umber that is very low it does

not absorb any x-rays so all the x-rays will reach the film and blacken it and that’s why air appears black on an x-ray image bone has a high density and that’s because it’s made up of substances which have a high proton number and as a result the absorption of x-rays by bone is high that means most of

the x-rays do not pass through bone and so do not reach the film and so cannot lock in the film and hence bone appears white and so the x-ray image is a shadow into phone soft-tissue has a lower density than bone but a higher density than air and it’s made up of substances of a low proton number so the absorption of x-rays by soft tissue is low most of the x-rays

can pass through soft tissue and reach the film to blacken it and so that’s why soft tissue appears gray become a soft tissue how similar proton numbers they absorb x-rays by similar amount so there’s little contrast that is different between soft tissues and an x-ray image and that’s why on a conventional x-ray image you cannot see soft tissue very well so for example the stomach or the intestines cannot be seen on this image and Medical Imaging – X-Ray Imaging Softwares Market & Contrast Media

that’s why a contrast medium for example barium or ID is needed to distinguish between the different soft tissues so if the patient drinks a barium meal which is a barium sulphate solution the barium is the contrast medium and it has a very high proton number and so it absorbs more x-rays than the surrounding tissue and so the outline or the shape of the Medical Imaging – X-Ray Imaging Softwares Market & Contrast Media

gastrointestinal tract can be seen very clearly blood vessels cannot be seen on a conventional x-ray image so if an iodine containing contrast me tube is injected into the blood stream then the outline of the blood vessels can be clearly seen and this will allow the detection of any blockages or narrowing of blood vessels or any bleeding from blood vessels Medical Imaging – X-Ray Imaging Softwares Market & Contrast Media
