Patent number: 10506998Abstract: In one embodiment, a method includes correlating, via a data correlator (120), contrast delivery information from an injector (118) for a contrast-enhanced imaging procedure with imaging data acquired by an imaging system (100) utilized for the procedure. In another embodiment, a method includes performing a pre-procedure validation check on at least one of an injector (118) or an imaging system (100) respectively based on at least one protocol parameter of the imaging system (100) or the injector (118) and generating, with the injector (118) or the imagining system (100), a value indicative of the validation check.Type: GrantFiled: March 15, 2010Date of Patent: December 17, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Paul Seltzer, Shlomo Gotman, Katrina M. Read, Ekta Dhawal Dharaiya

Patent number: 10219759Abstract: A method includes performing a contrast enhanced computed tomography (CT) scan of tissue of interest of a subject, with an imaging system having a radiation source and a detector array, in which a peak contrast enhancement of the tissue of interest, a full range of motion of the tissue of interest, and an entire volume of interest of the tissue of interest are concurrently imaged during a single rotation of the radiation source and the detector array of the imaging system over an entire or a predetermined sub-portion of a breathing cycle.Type: GrantFiled: July 6, 2015Date of Patent: March 5, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Paul Harvey Klahr, Ekta Dhawal Dharaiya, Scott Kenneth Pohlman, Randall Peter Luhta

Patent number: 9227462Abstract: An outboard sealing system cooperates with components of a heavy-duty vehicle wheel end assembly to retain lubricant in the assembly. The sealing system includes a seal that is disposed axially between an outboard bearing and a hubcap of a wheel end assembly. The seal also extends radially between an axle spindle nut and a surface of a bore formed in the hub of the wheel end assembly. The seal forms a barrier between the outboard bearing and the hubcap to reduce a flow of lubricant from a hub cavity into the hubcap. The sealing system retains lubricant in the wheel end assembly, prevents contaminants from entering the wheel end assembly, and retains the relative position of the outboard bearing in the hub during servicing. The sealing system preferably includes an additional barrier that reduces corrosion at the interface of the hubcap and an outboard face of the hub.Type: GrantFiled: December 18, 2013Date of Patent: January 5, 2016Assignee: Hendrickson USA, L.L.C.Inventors: Jay D. White, Dhawal Dharaiya

Publication number: 20140317905Abstract: A heavy-duty vehicle brake assembly with a sealing interface includes a brake shoe, which includes a shoe table mounted on a web and a brake lining mounted on the shoe table. The shoe table is coated with a zinc-rich coating to form the sealing interface between the brake lining and the shoe table. The sealing interface resists the formation of corrosion cells on the brake shoe table, which in turn reduces the build-up of significant rust between the brake shoe table and the brake shoe lining, thereby preventing cracking and potential dislodging of the lining, while also facilitating replacement of linings when they eventually wear. A method of constructing a heavy-duty vehicle brake assembly with a sealing interface is also provided.Type: ApplicationFiled: June 5, 2014Publication date: October 30, 2014Inventor: Dhawal Dharaiya
