| 20120097362 | SUBSEA COOLER AND METHOD FOR CLEANING THE SUBSEA COOLER - There is disclosed a subsea cooler for the cooling of a fluid flowing in a subsea flow line. The subsea cooler comprises an inlet and an outlet which are connectable to the subsea flow line and at least two cooling sections arranged in fluid communication with the inlet and the outlet of the subsea cooler. Each cooling section includes a plurality of cooling pipes which are configured such that they exchange heat energy with the surrounding sea water when the subsea cooler is in use. The subsea cooler is further provided with valve means such that the flow of fluid through the cooling sections may be regulated individually. There is also disclosed a method for removal of accumulated wax, hydrates and sand and debris which has accumulated in the subsea cooler wherein separate cooling section are shut off whereby the temperature of the fluid flowing through the subsea cooler is increased thereby melting the wax and hydrates, and whereby the speed of the fluid flow through the subsea cooler is increased thereby jetting out sand and debris. | 04-26-2012 |

| 20080221441 | Tumor grading from blood volume maps - An embodiment of the invention is to make possible a non-invasive grading of a tumor based on parameters determined from a frequency distribution (histogram) of values in a map representing cerebral blood volume (CBV) or cellular metabolism in the tumour. The method is especially applicable to brain tumors such as gliomas where histological grading is difficult. The invention provides a precise and consistent grading since it relies on values selected from the whole tumor (not just from hot spots); since it takes the diversity or heterogeneity of the vascularization into account by analyzing the frequency distribution (not just a mean value); and since it involves and allows for a more automated procedure wherein any subjective contributions from human operators is not critical to the resulting grading. CBV maps may be obtained by perfusion imaging using MRI or CT scanning. Cellular metabolism maps may be obtained from a glucose metabolism map obtained by positron emission tomography (PET). | 09-11-2008 |
| 20090191131 | USE OF PARTICULATE CONTRAST AGENTS IN DIAGNOSTIC IMAGING FOR STUDYING PHYSIOLOGICAL PARAMATERS - The present invention relates to a method of imaging of an animate human or non-human animal body, which method comprises: administering parenterally to said body a particulate material comprising a matrix or membrane material and at least one contrast generating species, which matrix or membrane material is responsive to a pre-selected physiological parameter whereby to alter the contrast efficacy of said species in response to a change in the value of said parameter; generating image data of at least part of said body in which said species is present; and generating therefrom a signal indicative of the value or variation of said parameter in said part of said body. The invention also relates to contrast media for imaging a physiological parameter. | 07-30-2009 |

| 20110170759 | VESSEL SEGMENTATION IN DCE MR IMAGING - The invention relates to segmenting blood vessels in perfusion MR images, more particularly, the invention relates to automated vessel removal in identified tumor regions prior to tumor grading. Pixels from a perfusion related map from dynamic contrast enhancement (DCE) MR images are clustered into arterial pixels and venous pixels by e.g. a k-means class cluster analysis. The analysis applies parameters representing the degree to which the tissue entirely consists of blood (such as relative blood volume (rBV), peak enhancement (ΔR | 07-14-2011 |
| 20110257519 | ESTIMATING AND CORRECTING FOR CONTRAST AGENT EXTRAVASATION IN TISSUE PERFUSION IMAGING - The invention provides a method, an image analysis software product, and a system for medical imaging analysis for estimating contrast agent extravasation in contrast agent based perfusion imaging such as MRI dynamic contrast enhanced (DCE) imaging, and in particular correction, compensation, or visualization of extravascular leakage of contrast agent in tumors. According to the invention, the effect of extravasation is directly manifested in the tail part of an observed, apparent residue function, R′(t), obtained directly by de-convoluting the expression C(t)=R′(t) | 10-20-2011 |

| 20090233503 | CONNECTION SYSTEM AND METHOD FOR CONNECTING AND DISCONNECTING A FLOATING UNIT TO AND FROM A BUOY WHICH IS CONNECTED TO A SUBSEA INSTALLATION - The present invention relates to a connection system and a method for connecting and disconnecting a floating unit to and from a buoy which is connected to a subsea installation, where the buoy comprises a first connection device for connecting pipes and/or lines for transfer of fluid, control signals and/or electric power between the buoy and the floating unit. The connection system further comprises a support structure which is laterally movable relative to the floating unit and a swivel stack arrangement movably mounted on the support structure. The swivel stack arrangement comprises a second connection device for connecting to the first connection device in the buoy; shut-off devices for opening and closing at least one of the pipes and/or lines in the first and second connection devices by connecting and disconnecting the buoy; and a turret bearing for rotating the buoy relative to the floating unit. | 09-17-2009 |
| 20100025043 | SYSTEM AND VESSEL FOR HYDROCARBON PRODUCTION AND METHOD FOR INTERVENTION ON SUBSEA EQUIPMENT - A system for operation and service of at least one hydrocarbon-producing well and of equipment, which is disposed under water, for further transport of the well stream, where the system comprises at least one pipeline, at least one booster unit, a vessel comprising an anchoring system about which the vessel can rotate or swivel, means for conducting an intervention on subsea equipment, means for communication with and control of the at least one well and other equipment, means for injecting chemicals into the well streams, means for transferring to and inserting pigs in the pipeline, means for production of energy for operation of subsea equipment, means for transferring energy from the means for production of energy to the booster unit and any other subsea equipment. | 02-04-2010 |
