In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water.n engineering, attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc.) and is represented by the attenuation coefficient of the medium in question.
PET Scan (Skull to Mid-Thigh) Cost and Procedure Information. Positron Emission Tomography, also called a PET scan, is a diagnostic examination that involves the acquisition of physiologic images based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient.
called bone growth stimulation, also known as osteogenesis stimulation. When bone is broken or bent, it generates an electrical field. is part of the bodyâs natural process that stimulates bone healing. When this healing process fails to occur naturally, bone growth stimulation can be used to help the process. Orthofix bone growth (osteogenesis) stimulation devices provide a safe, noninvasive treatment that helps promote healing in fractured bones and spinal fusions that have not healed or have difficulty healing.
