to visualize this joint space, the patient side of interest will be elevated 25-30 degrees centered medial to up side ASIS
what are Sacroiliac Joints
This part of the X-ray tube is made of borosilicate (Pyrex) glass that houses anode and cathode, provides high-vacuum environment, electrical insulation, and structural support.
what is the Glass Envelope
this part of the alimentary canal is where the small bowel meets the colon.
what is the ileocaecal valve
these devices are placed inside the bucky in front of the Image Receptor to increase image quality
what are grids
these gas filled chambers are part of Automatic Exposure Control and terminate exposure when sufficient amount of radiation has been reached.
