CT-SPECT fusion to correlate radiolabeled monoclonal antibody uptake with abdominal CT findings
1989
Ingår i: Radiology. - : American College of Radiology. - 0033-8419 .- 1527-1315. ; 172:3, s. 861-865
Tidskriftsartikel (refereegranskat) abstract
To enhance the information provided by computed tomography {(CT)} and single photon emission computed tomography {(SPECT)} performed with radiolabeled, anti-carcinoembryonic antigen monoclonal antibody {(MoAb)}, the authors performed fusion of these types of images from eight subjects with suspected colorectal adenocarcinoma. Section thickness and pixel size of the two studies were matched, coordinates of corresponding points from each study were identified, and {CT} sections were translated, rotated, and reprojected to match the corresponding {SPECT} scans. The {CT-SPECT} fusion enabled identification of anatomic sites of tumor-specific {MoAb} accumulation in four cases, showed non-specific {MoAb} accumulation in two, and helped confirm information only suggested by the two studies separately in one.

A Generic Raster Display for Medical Images : A Description
1986
Ingår i: Nineteenth Annual Hawaii International Conference on System Sciences 1986. Volume 3. - : IEEE and ACM. ; , s. 279-288
Konferensbidrag (refereegranskat) abstract
Two major difficulties associated with medical image processing are the diverse image formats that must be dealt with because of the differences in image sources and the number of incompatible display systems available for viewing images both before and after processing. We describe a very small set of primitives which need to be defined to utilize any raster display. When these primitives have been implemented for a particular device, then a standard set of image display programs can be compiled and images and the results of image processing can be displayed. The main purpose of this paper is to describe what a raster display looks like from the point of view of the programmer and to define the specific hardware and software data about the raster display which must be known in order to implement the small set of primitives.

Evaluation of Errors Using Graphical Techniques
1987
Ingår i: Proceedings of the Twentieth Annual Hawaii International Conference on System Sciences. - : IEEE and ACM. ; , s. 9-15
Konferensbidrag (refereegranskat) abstract
Anatomic localization in functional (such as PET) imaging, often requires a structural (such as CT or NMRI) study of the brain in the same plane. Some neuropsychiatric conditions make it difficult for a patient to hold his/her head immobile even when a rigid head holder is used. We studied the effect of tilt of the anatomic reference image, in this instance CT, relative to the functional image, here PET, on the quantification of receptor ligand concentration in anatomically defined regions of the brain.
