Capture solution xe cracked load6/1/2023 Once the absorption of the soft tissue has been subtracted, it is possible to determine the absorption of the beam by the bone and therefore the BMD Involves the emission of two X-ray beams with different energy levels, that collide with the body of the patient. Insensitive to changes in Bone Mineral Density (BMD)until 20 to 40% of bone mass lost The size of the monitor screens used in digital radiography is sufficient for 35 × 43 cm 2 radiographs to be displayed at a resolution of 2048 × 2560 pixels Ĭlear identification of distal radius fractures ĭifficult detection of hip and spine fractures (e.g., radiographs of the abdomen → 0.25 mGy) Įstimation of density variation (fracture risk prediction) by means of two indexes: Singh index for proximal femur and cortical–medullary index for hand radiographs Radiation dose: 40–50 times lower, if compared to computed tomography (CT) scans The atoms of the body prevent, in a percentage dependent on their atomic number, some photons from reaching the receptor, reproducing a “negative” image of the body Based on the interaction between a beam of photons (X-rays) directed from a source to a receptor.
