Appl. No.:

10/026381

Inventors:

Jinghan Ye - Fremont CA
Lingxiong Shao - Saratoga CA
Mary K. Durbin - San Jose CA

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

G01T 1166

US Classification:

25036304, 25036307

Abstract:

A gamma camera system and method are described which use multiple point sources to detect inaccuracies in detector translational and rotational alignment. In practice of the method of the preferred embodiment, three capillary tubes, each containing a drop of an isotope, are located in different planes and locations with respect to the axis of rotation of the detectors. A SPECT acquisition is performed and the point source projection data is processed to calculate the point source coordinates, from which center-of-rotation correction factors may be calculated. These correction factors are applied by mechanical and software adjustments to the gantry and acquisition systems of the camera to correct for both translational and rotational inaccuracies.

US Classification:

600411, 600407

Abstract:

A method for non-rigid registration and fusion of images with physiological modeled organ motions resulting from respiratory motion and cardiac motion that are mathematically modeled with physiological constraints. A method of combining images comprises the steps of obtaining a first image dataset () of a region of interest of a subject and obtaining a second image dataset () of the region of interest of the subject. Next, a general model of physiological motion for the region of interest is provided (). The general model of physiological motion is adapted with data derived from the first image data set () to provide a subject specific physiological model (). The subject specific physiological model is applied () to the second image dataset () to provide a combined image ().

International Classification:

G01T 1/24

US Classification:

25037009

Abstract:

A radiation detector package includes a radiation-sensitive solid-state element () having a first electrode () and a pixelated second electrode () disposed on opposite principal surfaces of the solid-state element. An electronics board () receives an electrical signal from the solid-state element responsive to radiation incident upon the radiation-sensitive solid-state element. A light-tight shield (′) shields at least the radiation-sensitive solid-state element from light exposure and compresses an insulating elastomer and metal element connector () between the pixilated electrode () and contact pads () on the electronics board.

International Classification:

G06K 9/00

US Classification:

382131

Abstract:

In an imaging method, estimated data is iteratively projected and backprojected. The iterative projecting and backprojecting includes projecting or backprojecting the estimated data along parallel paths each employing energy-dependent parameters appropriate for a different energy. During each iteration, the estimated data is adjusted based on comparison of the estimated data with measured data.

Abstract:

A physiological parameter monitor () monitors a cyclic physiological parameter and generates a cyclic parameter phase indicative signal. A radiation system () is disposed adjacent an examination region () to generate transmission radiation data and emission radiation data. First and second sorting devices () sort corresponding transmission and emission radiation data into transmission radiation data sets () and emission radiation data sets () corresponding to each of a plurality of the cyclic parameter phases. A data processor () reconstructs attenuation maps () from the transmission data for each of the plurality of cyclic parameter phases. An image processor () corrects the emission radiation data of each cyclic parameter phase with the attenuation map () of the same cyclic parameter phase and reconstructs the attenuation corrected emission data sets into an image representation for each cyclic parameter phase.

US Classification:

25036304, 25036308, 382131

Abstract:

An imaging system () includes at least one radiation detector () disposed adjacent a subject receiving aperture () to detect and measure at least one of emission and transmission radiation from a subject, the detector () at a plurality of projection angles. A processor () determines which radiation data belong to a field of view of the radiation detector () at each projection angle. An image processor () iteratively reconstructs the radiation detected only in the determined field of view into image representations. Truncated data is compensated by supplying the untruncated data from the projections taken at different angles at which the truncated data is untruncated.
