UM File # 3966BackgroundA computed tomography (CT) imaging system typically includes an x-ray source that projects fan- or cone-shaped x-ray beams through an object being imaged, such as a patient, to an array of radiation detectors. To reduce the total scan time required for multiple slices, a "helical" scan, which allow for large volumes of the object to be scanned at a quicker rate using one or more photon sources, are used. This technique generates a single helix from a fan beam helical scan, which, when mapped out by the fan beam, ...

By reducing the complexity of an MRI-generated fat spectrum, one is able to significantly improve the diagnostic utility of a scan with minimal effect on the scan time.
Organization: Indiana Univ-Purdue University Indianapolis
UC San Diego researchers have developed a VSASL method to address the first property. In conventional VSASL, the tagging of arterial blood is applied once before imaging and the tagged blood undergoes uniform T1 decay prior to image acquisition. If two or more VSS modules are used, some of the recovered tagged blood will be saturated again at a later time. Multiple VSS modules produces tagging that more closely approximates the ideal situation of being continuous. The tagged blood is therefore closer to saturation at the time of ...
Organization: Indiana Univ-Purdue University Indianapolis
UC San Diego researchers have developed an efficient method for estimating both the location and resonance offset of all feeding arteries of VEASL from randomly encoded data, allowing for identification of source vessels without prior knowledge of their locations. The method uses unipolar rather than bipolar vessel encoding gradient lobes providing the same encoding functionality, which results in nearly complete insensitivity to resonance offsets at the tagging plane.

Although devices such as scintillators can be used to detect radiation, for example, beta-radiation-emitting tracers in tumors, they have met with limited success due to their sensitivity to background gamma radiation. Since most beta-emitting isotopes also have gamma emissions, a detector that is sensitive to gamma rays is likely to be affected by background gamma radiation and lead to ambiguity in the location of the tumor. Existing beta-sensitive probes are limited in the face of metastasis from a small tumor, and typically require ...

If two or more VSS modules are used, some of the recovered tagged blood will be saturated again at a later time. Multiple VSS modules produces tagging that more closely approximates the ideal situation of being continuous. The tagged blood is therefore closer to saturation at the time of ...

UC San Diego researchers have developed an efficient method for estimating both the location and resonance offset of all feeding arteries of VEASL from randomly encoded data, allowing for identification of source vessels without prior knowledge of their locations. The method uses unipolar rather than bipolar vessel encoding gradient lobes providing the same encoding functionality, which results in nearly complete insensitivity to resonance offsets at the tagging plane.
A Restriction Spectrum Imaging Method and Device for Probing Tissue Microstructure
Organization: University of California, San Diego (UC San Diego)
UC San Diego researchers have developed an advanced diffusion MRI method, which can be used to probe tissue orientation structures over a range (or "spectrum") of hindered and restricted diffusion length scales with minimal assumptions on the underlying microarchitecture. The invention uses a linear mixture model to relate biological tissue parameters to diffusion MRI signals, which may be collected with various combinations of diffusion gradient strengths, diffusion times, diffusion weighting factors ("b-values"), and diffusion ...
Three-Dimensional Imaging of Biological Samples
Organization: Wisconsin Alumni Research Foundation (WARF)
The ability to analyze the microstructure of biological material in three dimensions is a valuable tool in gaining a clearer understanding of the basic mechanisms of life. When coupled with fluorescence techniques, for example, individual proteins and their interactions can be better visualized. One method to construct three-dimensional images begins by using a custom diamond knife to cut away consecutive thin layers from a block of biological material. These are stained and imaged using a high-sensitivity line-scan camera that repeatedly ...
PIN Diodes for Fast Photodetection, and High-Speed, High-Resolution Imaging and Sensing
Organization: Wisconsin Alumni Research Foundation (WARF)
PIN diodes are semiconductor devices that include an undoped intrinsic semiconductor region between the p-type and n-type regions. These diodes are commonly integrated as photodetectors on silicon CMOS chips for imaging sensing in digital cameras. Silicon CMOS technology offers several advantages, including ease of processing and large-scale integration; however, the speed of silicon-based PIN diodes tends to be slow. Germanium and silicon-germanium (SiGe) alloys offer promising alternative materials for high-quality, CMOS-compatible ...

The application has been used in a range of demanding applications including live concert streaming (1999), remote audio mixing (2000), collaborative performance (2001), distance masters classes over SDI (2002), and remote video interpreting of sign language using three simultaneous DV streams (2003) and won the SuperComputing 2005 conference award for "Most ...
Computer-Aided Diagnosis Software for Neurological Diseases
Organization: McGill University
McGill researchers have developed a completely automated software tool for the classification and early detection of neurological diseases. The invention consists in software for the analysis of large, non-specific areas from anatomical magnetic resonance images of patients to classify according to disease state. Based on no a priori assumptions, the underlying method escapes the pitfalls of the segmentation paradigm common to other detection approaches. This technique has potential applications in the area of localization of seizure focus ...

A Method for Polarization and Delivery of Polarized 129Xe Gas for Magnetic Resonance Imaging
Organization: University of Michigan
Background Medical imaging methods including MRI (Magnetic Resonance Imaging) and CAT (Computed Axial Tomography) are used to study the internal structure and operation of organs. MRI, in particular, is a predominant means of noninvasively studying internal systems employing large magnetic fields to align/polarize atoms within a sample. Radio frequency fields are used to change the alignment, which can be detected and used to construct images. This method is very robust but in systems with a low-density of atoms, such as the lungs, the signal ...
