Radiography is the principle imaging modality for bone. When an x-ray beam hits a patient, some of the x-rays are scattered, some are absorbed and some pass through unchanged. The appearance of the radiograph produced is dependent on the number of x-rays that pass through the patient and strike the x-ray plate. The more x-rays that strike the x-ray plate, the blacker the image appears.
We know that different tissues in the body absorb x-rays to differing degrees. Of all the tissues in the body, bone absorbs the most x-rays. This is the reason that bone appears white on a radiograph. Soft tissues absorb some but not all of the x-rays, so soft tissues appear on a radiograph in different shades of grey.
Oakham Veterinary Hospital uses a digital computer radiography system which produces radiographic images of excellent quality. The pictures are viewed on a computer screen and areas of particular interest can be enlarged to achieve more detail. The digital system also allows radiographs to be sent via email, for example to referring vets or farriers.
Oakham Veterinary Hospital also has a portable Eklin digital radiography system that affords our ambulatory vets the ability to obtain images of the highest diagnostic quality.
