Microchannel High Resolution X-Ray Sensor Having An Integrated Photomultiplier

View page
US Patent:
6452184, Sep 17, 2002
Filed:
Aug 30, 1999
Appl. No.:
09/385995
Inventors:
Nikhil R. Taskar - Ossining NY
John Victor D. Veliadis - New Rochelle NY
Vishal Chhabra - College Point NY
Neeta Pandit - Ossining NY
Rameshwar Nath Bhargava - Briarcliff Manor NY
Roger Delano - Sebastapol CA
Assignee:
Nanocrystal Imaging Corp. - Briarcliff Manor NY
International Classification:
G01T 120
US Classification:
250367, 2504831, 250461 R, 2504861
Abstract:
A composite phosphor screen for converting radiation, such as X-rays, into visible light. The screen includes a planar surface, which can be formed from glass, silicon or metal, which has etched therein a multiplicity of closely spaced microchannels having diameters of the order of 10 microns or less. Deposited within each of the microchannels is a multiplicity of phosphors which emit light when acted upon by radiation. A photomultiplier, which may be microchannel based, is integrated with the X-ray detector so as to provide an enhanced output for use with low level X-ray of for cine or fluoroscopy applications. The walls of the microchannels and/or the substrate surfaces include dielectric stack based light reflective coatings.

High Resolution High Output Microchannel Based Radiation Sensor

US Patent:
6534772, Mar 18, 2003
Filed:
Oct 16, 2000
Appl. No.:
09/688662
Inventors:
Vishal Chhabra - Ossining NY
Rameshwar Nath Bhargava - Briarcliff Manor NY
Dennis Gallagher - Stamford CT
Samuel P. Herko - Ossining NY
Bharati S. Kulkarni - Cortlandt Manor NY
Nikhil R. Taskar - New York NY
Aleksey Yekimov - White Plains NY
Assignee:
Nanocrystal Imaging Corp. - Briarcliff Manor NY
International Classification:
G01T 120
US Classification:
250367, 2504831, 2504861
Abstract:
A microchannel phosphor screen for converting radiation, such as X-rays, into visible light. The screen includes a planar surface, which can be formed from glass, silicon or metal, which has etched therein a multiplicity of closely spaced microchannels having diameters of the order of 40 microns or less. Deposited within each of the microchannels is a multiplicity of phosphors which emit light when acted upon by radiation. The dimensions of the microchannel and the phosphors and the relationship between the microchannels and the phosphors is optimized so that the light output compares favorably with lower resolution non microchannel based scintillation screens. A photomultiplier can be integrated with the X-ray detector so as to provide an enhanced output for use with low level X-ray of for cine or fluoroscopy applications.

X-Ray Imaging System Incorporating Pixelated X-Ray Source And Synchronized Detector

View page
US Patent:
6674837, Jan 6, 2004
Filed:
Jun 14, 2002
Appl. No.:
10/172704
Inventors:
Nikhil R. Taskar - Scarsdale NY
Rameshwar Nath Bhargava - Ossining NY
Paul J. Patt - Northborough MA
Assignee:
Nan Crystal Imaging Corporation - Briarcliff Manor NY
International Classification:
H01J 3500
US Classification:
378122, 378 92
Abstract:
An X-ray imaging system utilizing a pixelated X-ray source and a X-ray imaging detector operated synchronously. The imaging system may be used in industrial and medical applications. The X-ray source and X-ray detector are synchronized such that a corresponding area of the X-ray detector is activated when the corresponding area of the X-ray source is emitting X-rays. Synchronized and adaptive emission and detection of the X-rays results in scatter rejection, improved image quality, and optimum exposure and dose reduction.

Nanocrystalline Based Phosphors And Photonic Structures For Solid State Lighting

View page
US Patent:
6734465, May 11, 2004
Filed:
Nov 19, 2002
Appl. No.:
10/299410
Inventors:
Nikhil R. Taskar - Scarsdale NY
Rameshwar Nath Bhargava - Briarcliff Manor NY
Assignee:
Nanocrystals Technology LP - Briarcliff Manor NY
International Classification:
H01L 2715
US Classification:
257 80, 257100
Abstract:
A photonic structure for âwhiteâ light generation by phosphors under the excitation of a LED. The photonic structure mounts the LED and an optically transparent matrix having dispersed therein phosphors which will emit light under the excitation of the radiation of the LED. The transparent matrix may include nanoparticles for matching the index of refraction of the material of the matrix to that of the light generating phosphors. The matrix material may be readily formed by molding and formed into a variety of shapes including lenses for focusing the emitted light. A large number of the photonic structures may be arranged on a substrate to provide even illumination or other purposes. The phosphors dispersed in the matrix are preferably nanocrystalline.

Self-Aligning Qca Based Nanomaterials

US Patent:
7175778, Feb 13, 2007
Filed:
May 12, 2003
Appl. No.:
10/436289
Inventors:
Rameshwar Nath Bhargava - Ossining NY, US
Vishal Chhabra - Ossining NY, US
Assignee:
Nanocrystals Technology LP - Briarcliff Manor NY
International Classification:
H01F 1/00
C09K 11/02
US Classification:
252 6251R, 977774, 977779, 977783, 977811, 977838, 977834, 2523014 R, 2523014 S, 2523014 P, 2523014 F, 2523014 H, 2523015, 2523016 R, 2523016 S, 2523016 P, 2523016 F, 428403
Abstract:
The present application is directed to the preparation and use of a class of nanoparticles called Quantum Confined Atoms or QCA's. A QCA is a particle of material comprising a plurality of host atoms in a nanoparticle of a size of less than 10 nm with a single atom of a dopant (or activator) confined within. The QCA's have unique luminescent and optical properties and thus can act as a very efficient nanophosphor which generate polarized light and can operate as a laser and a nanomagnet. An anti-agglomeration coating surrounding the nanoparticles can prevent clumping and loss of the enhanced properties.

US Patent:
7993541, Aug 9, 2011
Filed:
Feb 12, 2007
Appl. No.:
11/705383
Inventors:
Rameshwar Nath Bhargava - Ossining NY, US
Haranath Divi - Croton on Hudson NY, US
Adosh Mehta - Highland Mills NY, US
Assignee:
Nanocrystals Technology LP - Briarcliff Manor NY
International Classification:
H01F 1/00
US Classification:
252 6251R, 977774, 977811, 977824, 977830, 977838, 428403, 428407
Abstract:
The present application is directed to the preparation and use of a class of nanoparticles that contain a single Quantum Confined dopant. A QCA nanocrystal comprises of a plurality of host atoms in a nanocrystal of a size of less than 10 nm with a single atom of a dopant (or activator). This single QCA dopant, when confined, becomes polarized and creates a large magnetic-moment in a nanosize host that contains atoms of unpaired spins. The quantum confined atom (QCA) which is now pinned, triggers the alignment of the host atoms resulting in nanosize magnetic domain. Engineering of nanomagnets based on QCA nanoparticles can be used in different applications such as: sensors, drug delivery, bio-tagging, cell/DNA tagging, magnetic memories and others.

Pumped Solid-State Lasers Comprising Doped Nanocrystal Phosphors

View page
US Patent:
54229073, Jun 6, 1995
Filed:
May 20, 1994
Appl. No.:
8/246944
Inventors:
Rameshwar N. Bhargava - Ossining NY
International Classification:
H01S 314
US Classification:
372 68
Abstract:
An optically-pumped or electron-beam-pumped solid-state laser employing as the phosphor material doped nanocrystal particles which as a result of quantum confinement can be caused to exhibit discrete levels in its conduction band that can overlap with the corresponding levels in the doping activator such that resonant energy transfer of excited carriers from the conduction band of the phosphor host to that of the activator will occur. The energy levels in the activator are such as to allow very fast carrier transitions to an intermediate level and a slower radiative transition to a ground state. The result is an energy level structure similar to that of a four-level laser but capable of more efficient conversion of the pumping energy to photon generation.
