Abstract: A medical imaging device includes an x-ray source disposed at a first end of an arm, and an x-ray detector disposed at a second end of the arm opposite of the x-ray source. At least one of the x-ray source, the x-ray detector, and a portion of the arm are selectively adjustable with respect to the arm.

Abstract: The present invention relates to the use of (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4?-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid of formula (I), prefer-ably in form of one of its salts or solvates or hydrates, preferably (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4?-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid in form of monohydrate (I) of formula (I-M-I) or (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4?-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)-ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid inform of mono hydrate (II) of formula (I-M-II), in the inhalative treatment of cardiopulmonary and pulmonary disorders, such as pulmonary arterial hypertension (P AH), chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary hypertension (PH) associated with chronic lung disease (PH group 3) such as pulmonary hypertension in chronic obstructive pulmo

Abstract: A method and apparatus for generating a molecular or atomic fluorine jet or beam under vacuum for etching surfaces. The apparatus uses a hollow crystalline tube preferably fabricated from a crystal of a Group II fluoride such as magnesium fluoride. A terminal portion of the tube is heated to over 1000.degree. C. and a mixture of fluorine gas and an inert carrier gas is induced under pressure into the tube. An atomic fluorine jet is emitted from the opposite end of the tube. The jet can be collimated into a beam and can be directed at masked surfaces for selective etching of the surface. The atomic fluorine source has a very high intensity resulting in rapid etching of materials and as a beam is capable of highly anisotropic etching. The jet may be primarily molecular fluorine if the tube is heated to a lower temperature.
