X-Ray Intensifying Screens
X-ray intensifying screens are fluorescent phosphor sheets in film cassettes that convert X-rays to visible light, cutting patient dose. Calcium tungstate dominated from 1896 until rare-earth phosphors arrived in the 1970s.
X-ray luminescence computed tomography
X-ray luminescence computed tomography (XLCT) is a hybrid imaging method, reported by Guillem Pratx and colleagues in 2010, that maps x-ray-excited luminescent nanoparticles inside an object from surface optical measurements.
Xeromammography
Xeromammography is xeroradiography of the breast, a filmless electrostatic X-ray method using selenium plates and dry toner, commercialized by Xerox around 1970-1971, widely used in the 1970s, and replaced by screen-film and digital mammography.
Xeroradiography
Xeroradiography is a dry electrostatic method for recording X-ray images using a selenium-coated plate and charged powder toner. It was widely used in mammography in the 1970s.
Zirconium Zr-89 girentuximab (Zircaix)
Zirconium Zr-89 girentuximab (Zircaix, TLX250-CDx, 89Zr-DFO-girentuximab) is a zirconium-89-labeled anti-CAIX antibody for PET/CT imaging of clear cell renal cell carcinoma; ZIRCON phase 3 showed 85.5% sensitivity and 87.0% specificity.
