What equipment is used in X-rays?
Radiography equipment used for x-raying artwork. Medical x-ray systems. X-ray fluorescence analyzers (portable and bench-top) X-ray photoelectron spectrometers.
What is a trauma x-ray?
The Standard Trauma Series has been composed of X-rays of the chest, pelvis and cervical spine. The CXR performed is usually supine (AP) rather than erect (PA) owing to the inability to clear the spine and sit the patient up. The CXR should include imaging of both clavicles, ribs, lungs, mediastinum and diaphragm.
When imaging trauma patients which method should the radiographer use?
13-3 Dedicated C-arm–type trauma radiographic room with patient on the table. (Courtesy Siemens Healthcare.) Computed tomography (CT) is widely used for imaging of trauma patients.
What imaging modalities are part of the trauma work up?
Trauma to the thorax typically is assessed with radiography and CT, and CT is recommended for assesment of abdominal and pelvic trauma.
What is a trauma scan?
The standard CT protocol for whole-body trauma scanning consists of a noncontrast-enhanced scan of the head and cervical spine, followed by an arterial phase scan of the chest at 30 seconds and a portal venous phase scan of the abdomen and pelvis at 70 seconds.
What are the 5 basic radiographic densities?
The five basic radiographic densities: air, fat, water (soft tissue), bone, and metal. Air is the most radiolucent (blackest) and metal is the most radiopaque (whitest).
Which imaging modality is often used to evaluate trauma to the abdomen?
CT imaging is the diagnostic tool of choice for the evaluation of abdominal injury due to blunt trauma in haemodynamically-stable patients (1). CT scans can provide a rapid and accurate appraisal of the abdominal viscera, retroperitoneum and abdominal wall (2).
Which imaging modality is best for trauma?
Ultrasound. Ultrasound is utilised in the form of Focused Assessment with Sonography in Trauma (FAST) at all trauma calls and is now the diagnostic imaging of choice in the unstable trauma patient with intra-abdominal haemorrhage who requires urgent surgery.
What is a full trauma CT?
Why is CT Utilised in trauma?
CT angiogram neck/circle of Willis: penetrating neck injuries or risk factors for blunt cerebrovascular injuries. delayed phase of the abdomen/pelvis: useful to assess for contrast pooling/contrast extravasation indicative of active bleeding.
What controls radiographic density?
When the mA or exposure time increases, the number of x-ray photons generated at the anode increases linearly without increasing beam energy. This will result in a higher number of photons reaching the receptor and this leads to an overall increase in the density of the radiographic image (Figure 2).
