Patent number: 8013307Abstract: An imaging system (10) includes at least one radiation detector (20) disposed adjacent a subject receiving aperture (18) to detect and measure at least one of emission and transmission radiation from a subject, the detector (20) at a plurality of projection angles. A processor (64) determines which radiation data belong to a field of view of the radiation detector (20) at each projection angle. An image processor (70, 72) 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.Type: GrantFiled: December 5, 2005Date of Patent: September 6, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Jinghan Ye, Mary K.

Patent number: 7907698Abstract: A physiological parameter monitor (44) monitors a cyclic physiological parameter and generates a cyclic parameter phase indicative signal. A radiation system (8) is disposed adjacent an examination region (18, 28) to generate transmission radiation data and emission radiation data.

Patent number: 7865005Abstract: 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.Type: GrantFiled: January 25, 2007Date of Patent: January 4, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Jinghan Ye, Mary K.

Patent number: 7840052Abstract: A medical imaging system (10) includes at least one radiation detection head (16) disposed adjacent a subject receiving aperture (18) to detect radiation from a subject. The detected radiation is reconstructed into at least one initial 2D projection image (?). Resolution in each initial 2D image (?) is restored by using the extended iterative constrained deconvolution algorithm by incorporating different estimates of the system response function which estimates correspond to different distances between the detection head and the origins of the detected radiation. Measured response functions are used to restore a series of images. The optimal image is determined by automatic searching with the figure of merit, by user's observation, or by using blind deconvolution for a concurrent estimating of the system response function and updating the original image.Type: GrantFiled: November 4, 2005Date of Patent: November 23, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Zuo Zhao, Lingxiong Shao, Jinghan Ye
