Abstract: A system and method are disclosed for capturing a radiographic or autoradiographic image of an object, in which a support member is provided to receive the object in an immobilized state; a phosphor screen is provided to transduce ionizing radiation from the source to visible light; film or a digital capture device is provided for capturing an image using the visible light; and the phosphor screen is moved incrementally to facilitate reduction of phosphor screen mottle.

Abstract: A method for forming a sequence of images of a subject obtains at least first and second image sets of the subject, each image set having a given angular displacement relative to an axis of rotation of the subject, each image set having at least a first component image of a first diagnostic modality at the given angular displacement and a second component image that is co-registered to the first component image at the given angular displacement. The first image set is selected as the selected image set for display. A synthesized image is formed by combining image data for the at least first and second component images of the selected image set and the synthesized image is displayed.

Abstract: A method and apparatus are disclosed for measuring long bone density of small animals. A phosphor screen or plate is provided of a type that transduces incident ionizing radiation to emitted light. A small animal is positioned before the phosphor screen or plate and exposed to soft X-radiation having an energy level in the range of 11 to 16 Kev. Light emitted by the phosphor screen or plate is captured using a digital camera and a digital X-ray image is prepared of a long bone of the animal. The X-ray image is transformed into an X-ray density image and a region of interest is defined on the long bone in the X-ray density image. At least one row of pixels is scanned within the region of interest of the X-ray density image. A nonlinear least squares analysis of data obtained from the scanning step is conducted using a cylindrical model for the long bone within the region of interest.

Abstract: Methods are disclosed for (A) adjusting the physical, spatial orientation of an immobilized subject in a multi-modal imaging system so as substantially to reproduce or match the physical, spatial orientation of a reference subject, wherein the reference subject is either (a) the same or (b) a different subject, either (1) during a prior imaging session for a later imaging session, or, in the case where a plurality of subjects is imaged in one imaging session, (2) during a contemporaneous imaging session; and (B) adjusting the virtual, spatial orientation of an immobilized subject in a set of multi-modal images.
