Prior art

The USPTO database reveals several prior art documents cited against US patent 8265353. The following are the most relevant based on their direct citation within the patent or by Unified Patents as "winning prior art".

Most Relevant Prior Art for US Patent 8265353

1. FR2736454A1

• Full Citation: FR2736454A1 (also cited as US5889525A, which appears to be its US counterpart). [cite: The full patent text of US8265353B2 lists FR2736454A1 under "Citations (15)" and US5889525A under "Patent Citations (17)".]
• Publication/Filing Date: Publication date: 1997-01-10 (FR2736454A1), Filing date: 1995-07-03. [cite: The full patent text of US8265353B2 lists these dates.]
• Brief Description: This patent describes a "Process for reconstructing three-dimensional images on a mobile or deformable object." It pertains to image correction methods by estimating displacement fields, particularly applied to attenuation images. The '353 patent mentions this as a known method for estimating patient movement between two phases.
• Potential Anticipated Claims (35 U.S.C. § 102): This reference explicitly addresses estimating movement and reconstructing images of a mobile object. This could potentially anticipate aspects of claims 1 (obtaining images, associating with movement states, forming an image) and 7 (forming displacement fields) and 9 (estimating movement of the mobile object based on images to form displacement fields).

2. FR2826157A1

• Full Citation: FR2826157A1 (also cited as US20040170246A1). [cite: The full patent text of US8265353B2 lists FR2826157A1 under "Citations (15)" and US20040170246A1 under "Patent Citations (17)".]
• Publication/Filing Date: Publication date: 2002-12-20 (FR2826157A1), Filing date: 2001-06-15. [cite: The full patent text of US8265353B2 lists these dates.]
• Brief Description: Titled "Method for reconstructing an image of an evolving object," this patent is cited in US8265353 as an example of digital correction of measurements and images, taking into account object displacements between series of measurements. It describes estimating object movements by displacement fields.
• Potential Anticipated Claims (35 U.S.C. § 102): Similar to FR2736454A1, this reference's focus on estimating object movements via displacement fields for image correction could potentially anticipate elements of claims 1, 7, and 9.

3. "Attenuation correction for a combined 3D PET/CT scanner" by Kinahan et al.

• Full Citation: Kinahan, P. E., et al. "Attenuation correction for a combined 3D PET/CT scanner." Med. Phys. 25(10), October 1998, p. 2046-2053. [cite: The full patent text of US8265353B2 lists this non-patent citation.]
• Publication/Filing Date: October 1998. [cite: The full patent text of US8265353B2 lists this date.]
• Brief Description: This non-patent literature describes devices for simultaneously acquiring both attenuation (CT) and emission (PET) images. The '353 patent acknowledges this prior art in the context of combined acquisition but distinguishes itself by its method of analog combination and movement compensation.
• Potential Anticipated Claims (35 U.S.C. § 102): This reference demonstrates the prior art of acquiring images using two different imaging techniques (attenuation and emission) simultaneously. This directly relates to the broad concept of "obtaining a plurality of first images... using a first imaging technique" and "obtaining a plurality of second images... using a second imaging technique," as stated in claim 1 and claim 12. Specifically, it relates to the choice of imaging techniques in claim 5 ("radiation attenuation technique and said second imaging technique is a radiation emission technique") and claim 14.

4. WO 2002013036

• Full Citation: WO 2002013036. [cite: Unified Patents lists this as "DOWNLOAD WINNING PRIOR ART" for US 8,265,353.]
• Publication/Filing Date: Not explicitly stated in the provided text, but Unified Patents lists it as "winning prior art."
• Brief Description: Unified Patents has identified this as "winning prior art" for US 8,265,353, generally relating to auto manufacturing and supplies.
• Potential Anticipated Claims (35 U.S.C. § 102): Without the full text of WO 2002013036, specific claim anticipation cannot be determined. However, its designation as "winning prior art" by Unified Patents suggests it likely anticipates elements of at least claim 1, which broadly covers forming an image of a mobile object using two different imaging techniques and independent sensor systems. The fact that it relates to "auto manufacturing and supplies" suggests a potential application in fields beyond medical imagery, possibly broadening its impact on the claims.

It's important to note that the provided text from Unified Patents also mentions other winning prior art, such as US 7,404,644 and US 7,736,019, for US 8,265,353, but does not provide details of these references. Without further information, a detailed analysis of their potential anticipation of specific claims is not possible.
