Digital tomosynthesis (DT) gives better diagnostic information than 2D X-ray, rivalling CT. However, tomosynthesis reconstruction requires sophisticated algorithms and a powerful computer, and can take several minutes to complete. The present invention takes a single x-ray image of a body 50 using multiple sources. In normal tomography and tomosynthesis imaging, such overlapping cones would lead to un-reconstructable data as significant overlap, in general, can’t be deconvolved and is not soluble. However, here, for the detection and localization of dense, compact objects 40, a location of an object 40 may be determined in three spatial dimensions from a single two-dimensional image. That is, processor-intensive reconstruction of a three-dimensional volume may be avoided.

A multi-modal visualization system (MMVS) is provided, which may be used to analyze and visualize bioimaging data, objects, and pointers, such as neuroimaging data, surgical tools, and pointing rods. MMVS can integrate multiple bioimaging modalities to visualize a plurality of bioimaging datasets simultaneously, such as anatomical bioimaging data and functional bioimaging data.

A diagnostic imaging system utilizing a reduced crystal design pattern is utilized to image a subject and collect event data. The reduced crystal design pattern includes filled crystal locations and empty crystal locations. A processor accounts for empty crystal locations by selecting windows that include nearest neighbor filled crystal locations. The nearest neighbor filled crystal locations include event data which is averaged by the processor and assigned to the empty crystal location. A weighted average based on distance or event strength is incorporated.

An image processing device includes: an image data acquisition unit for acquiring SPECT image data of a brain; a brain-region ROI definition unit for defining a brain-region ROI in the SPECT image; a striatum ROI definition unit for defining a striatum ROI in the SPECT image; and a threshold determination unit for, based on counts in the SPECT image's background which is the brain-region ROI except the striatum ROI, determining a threshold for distinguishing ventricles and sulci in the SPECT image; a region distinction unit for distinguishing between a region whose number of counts is smaller than or equal to the threshold and a region whose number of counts is larger than the threshold.

Disclosed is a novel method of obtaining transmission scan data in a PET scanner by incorporating one or more stationary gamma-ray sources that provide forward scattered gamma-photons that can be used as transmission imaging radiation.

An image processing apparatus, an image display system, an image processing method, and a program by which it is possible to display an optimum three dimensional image when display is switched from a two dimensional tomographic image to a three dimensional image are provided. The processor (14) outputs a tomographic image display signal representing a two dimensional tomographic image included in a first tomographic image group based on first imaging data obtained by imaging a subject, extracts a second tomographic image group having a smaller interval between tomographic images than the first tomographic image group, on the basis of second imaging data acquired in imaging corresponding to the imaging for acquiring the first imaging data, if a display switching signal indicating switching from display of the two dimensional tomographic image to display of a three dimensional image is acquired, and outputs a three dimensional image display signal representing a three dimensional image generated on the basis of the extracted second tomographic image group.

An image processing apparatus includes at least one processor, and the processor derives three-dimensional coordinate information that defines a position of a structure in a tomographic plane from a tomographic image including the structure, and that defines a position of an end part of the structure outside the tomographic plane in a direction intersecting the tomographic image.

Disclosed herein is a method, comprising: causing emission of characteristic X-rays of a chemical element in an object by directing radiation to the object; capturing images of the object using the radiation that has transmitted through the object; capturing images of the chemical element in the object using the characteristic X-rays; reconstructing a three-dimensional image of the object based on the images of the object; determining a three-dimensional distribution of the chemical element in the object based on the images of the chemical element; and superposing the three-dimensional image of the object and the three-dimensional distribution of the chemical element in the object to form a superposed image of the object. The radiation directed to the object comes from multiple radiation sources. The images are captured with multiple image sensors. The radiation sources and the image sensors are stationary with respect to the object.
