Patent number: 11426605Abstract: A device may include a collimator positioned between a radiation source of a scanner and a bore of the scanner. The bore may include a detecting region configured to accommodate a subject. The collimator may be configured to prevent at least one portion of radiation rays emitted from the radiation source from being incident on the subject. The device may further include a first filter and a second filter. The first filter may be positioned between the radiation source and the collimator. The second filter may be positioned between the collimator and the bore. The first filter and the second filter may be configured to adjust a distribution of radiation impinging upon the subject.Type: GrantFiled: October 12, 2020Date of Patent: August 30, 2022Assignee: UIH AMERICA, INC.Inventor: Ronald Sharpless

Patent number: 9314220Abstract: The invention relates to a rotor comprising a radiation source having a focal spot for radiating beam towards a subject, detection means for generating signals responsive to energy attenuation of said beam and a circular body having a cavity for housing the radiation source, and a circle arc-shaped surface on which the detection means are mounted. The circle arc-shaped surface is placed opposite to the cavity with respect to the subject, said cavity comprising an inside surface mounted with a shield for shielding the radiation not towards the subject. In this way, the conventional housing for radiation source and shielding are removed, resulting in reduction of focal spot motion caused by motion of the conventional housing. Furthermore, this invention proposes to mount the detection means directly on the circular body without an intermediate structural housing that reduces the detector modules motion relative to the focal spot.Type: GrantFiled: December 16, 2008Date of Patent: April 19, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Randall Peter Luhta, Ronald Sharpless, Lester Miller

Publication number: 20070030004Abstract: A magnetic resonance imaging scanner includes a generally cylindrical main magnet assembly (10) that defines a cylinder axis (16). A first set of shims (60) are rigidly positioned inside the magnet assembly (10) at about a first distance (d1) relative to the cylinder axis (16). A second set of shims (62) are rigidly positioned inside the main magnet assembly (10) at about a second distance (d2) relative to the cylinder axis (16). The second distance (d2) is different from the first distance (d1). A generally cylindrical radio frequency coil (26) is arranged inside the main magnet assembly (10) at about a third distance (d3) relative to the cylinder axis (16). A plurality of gradient coils (20) are arranged inside the main magnet assembly (10) at about a fourth distance (d4) relative to the cylinder axis (16).Type: ApplicationFiled: May 19, 2004Publication date: February 8, 2007Inventors: William Amor, Dennis Everett, Jerome Alden, Robert Henderson, Terrence Doyle, Ronald Sharpless, Gerardus Mulder, Gerardus Peeren
