Screen Film Radiography 1-Screen Film Radiography The imaging principle: · Patient’s body is composed of different materials with different attenuation properties. · If an X-ray incident on the patient, the high-density material (Bone) will absorb a high amount of radiation, while the…
Why Increasing the kVs utilised during imagine acquisition lowers patient dosage because more photons with higher energy pass through the patient to reach the detector. However, the resulting image has less contrast. • Increasing filtration reduces the number of low-energy…
Imaging Two PET-Tracers Simultaneously Introduction: Medical imaging techniques such as Positron Emission Tomography (PET) are extensively employed in preclinical and clinical settings. Fluorine-18-fluorodeoxyglucose, or 18F-FDG, is a radiotracer that is used in PET/CT scans as part of cancer care to…
