Abstract: A method displays ultrasound color flow image data in a plurality of output frames by continuously acquiring color flow image data. Each output frame includes a plurality of scan lines that collectively represent a field of view for an ultrasound image. The method includes sequentially transmitting a plurality of ultrasound beams. For each of the transmitted beams, multiple receive beams are formed along respective parallel scan lines. As the sequence progresses, sets of co-linear receive beams are formed along each of the respective scan lines at a predetermined rate both within a particular frame and between successive frames. The method also includes processing the sets of co-linear receive beams along each of the respective scan lines to generate color flow image data corresponding to the respective scan lines, and displaying a color flow image representing the generated color flow image data.

Abstract: A method for generating classifiers for identifying neuropsychiatric disease includes acquiring functional neuroimaging data. The acquired functional neuroimaging data may be registered to an atlas of the brain. A discriminative mask is generated based on the registered functional neuroimaging data and the generated discriminative mask is applied to the registered functional neuroimaging data. One or more classifiers are generated for identifying neuropsychiatric disease based on the masked functional neuroimaging data. The accuracy of the generated classifiers may be verified. The generated classifiers may then be used to identify neuropsychiatric disease.

Abstract: An implantable device has a body that is substantially rigid and has an imageable shape. The body is further bioabsorbable and may contain permanent metallic elements to aid in its imaging. When the device is implanted in a resected cavity in soft tissue, it can cause the cavity to conform substantially to a known imageable shape. The implantable device is further imageable due to its attenuation properties being different from those of soft tissue such that the boundaries of the tissue corresponding to the predetermined shape can be determined.

Abstract: A mechanism of quantitative dual-spectrum IR imaging (QDS-IR) system for examining the breast cancer is reported. The major mechanism of the system is a pair of long-wave Infra-red (LIR) and middle-wave Infra-red (MIR) cameras with the keen temperature sensitivity and the high spatial resolution. The optical axes of cameras are calibrated by the help of two calibration makers set up on the seat for carrying an object to make them parallel to each other and locate on the same level. The design provides an imaging system with the high reproducibility supported by 7 free degrees and the high adjustability. The proposed system could ensure the positions of the object and two cameras are the same at the different time points and find the best relative positions between the seat and two cameras for the objects with different body types. Therefore, it has potential ability to detect breast cancer or monitor the effect of chemotherapy.
