Patent EP-0515641-A4 (EP)
Title: Coronary tracking display
Inventor: WHITING JAMES S
IPC: A61M25/01
Filed: 1991-11-12
Abstract: A method of displaying details of a coronary artery lesion in a cineangiogram, by adjusting each frame of the cineangiogram so that the lesion is continually displayed at a fixed location on a display. The remaining cardiac anatomy appears to move, in background, past a stationary arterial segment, thus making the displayed arterial segment easier to identify and to examine by medical personnel. Cineangiographic image frames are digitized and processed by a processor and the image frames are digitally shifted to place the arterial segment in substantially the same viewing location in each frame. Sequential image frames may be presented to the viewer as a stereoscopic pair, to produce pseudostereopsis. The arterial segment appears to the viewer in foreground, as if it was floating in front of the remaining cardiac anatomy. Image frames may be further processed to aid examination by medical personnel. The processor may make quantitative measurements of the cineangiogram and may display results of those measurements to aid review of the cineangiogram. Frames may be averaged to reduce quantum noise and to blur any structure noise; frames may be compared with prior cineangiograms to increase clarity or contrast. Coordinate adjustments for a cineangiogram may help guide therapeutic procedures, or may help enhance other imaging procedures such as fluoroscopy.

Title: Wastewater treatment process and apparatus.
Inventor: MACLAREN DAVID S
IPC: C02F101/30
Filed: 1993-02-03
Abstract: A wastewater treatment plant for removal of organic matter, suspended solids and other pollutants comprising a pre-treatment chamber, a biofilm-aeration chamber and a settling chamber. Biofilm grows on biofilm support structure which is stationary and submerged in the mixed liquor of the biofilm aeration chamber. The combination of submerged or surface aeration and suspended solids particle size reduction occurs thereby creating a sufficient fluid flow within the biofilm aeration chamber. This combination of sufficient fluid flow, and reduced size suspended organic particles results in the efficient digestion of organic matter and pollutants by the biofilm growing on the biofilm support structure submerged in the biofilm aeration chamber. This results in a vastly more effective digestive process than conventional processes producing no sludge. Further, resulting treated effluent has a high dissolved oxygen content and low BOD and SS. The apparatus and process has the following advantages: low MLSS concentration, short biofilm incubation time, no clogging of the system, good response to shock loading, high DO in the effluent, consistent effluent quality, sludge is eliminated, wastewater treatment duration is shortened, the process is not temperature sensitive, plant design is greatly simplified, plants of the present invention are small by comparison to conventional plants, the present invention can be a significant step in the treatment of drinking water, energy consumption during treatment is low, the present invention is very cost effective, the process permits other purification processes to be used and the process is volumetrically and BOD insensitive.
