Abstract: A tumor cell xenograft model in zebrafish, and methods of constructing and using the same. Primary cells dissociated from the tumor tissue of a patient are transplanted into zebrafish, so as to obtain a patient-derived tumor xenograft model. The tumor xenograft model retains the pathological features of human gastric cancer tissues in clinic, has higher clinical relevance, and can be used in the systematic research into the mechanisms underlying the proliferation, metastasis, spread and drug resistance of tumors, and to screen effective drugs for tumor treatments.

The image data includes bony structures, and the method comprises segmenting pixels within the image data into areas based on the pixel's CT number. A first area represents a combination of soft tissue and lower density bones and a second area represents higher density bones. A subset of pixels is identified within the first area representative of the lower density bones. An enhancement is applied to the subset of pixels within the first area and to the second area to create an enhanced dataset, and a locally enhanced image is generated based on the image data and the enhanced dataset.

The image plane comprises the same anatomical structure. First and second weighting functions are calculated for first and second images based on first and second tube positions of an x-ray tube. The first and second images correspond to the image plane and are from the first and second view streams, respectively. The first and second tube positions also correspond to the image plane. A weighted image is then formed based on the first and second weighting functions and the first and second images.

Abstract: The present invention is directed to a method and system of blending data acquired from neighboring partial-scans. Data is acquired from an imaging volume in a series of fractional or partial-scans. Each partial-scan samples a fraction of the imaging volume. During reconstruction, data from the partial-scans are combined to compensate for the unsampled portion of the imaging volume that is experienced in any partial-scan alone.
