20100298706RESPIRATORY-GATED THERAPY ASSESSMENT WITH ULTRASONIC CONTRAST AGENTS - An ultrasonic imaging apparatus and method are described for monitoring the progress of therapy for pathology such as lesions, tumors, and metastases by means of contrast agent imaging. A sequence of images are acquired as a bolus of contrast agent infuses the tissue containing the pathology. A contrast wash-in time parameter is calculated for both the tumor and normal tissue, and a ratio is calculated of the two wash-in time parameters (called WITR) which removes the effects of variations in the procedure from one therapy monitoring session to another. A difference curve of the time-intensity curves of the pathology and normal tissue is also produced, which is similarly immune to procedural variations. The motional effects of respiration can be taken into account by detecting the position of a landmark such as the diaphragm in each of the images of the sequence and discarding from processing those which exhibit a change in the position of the landmark relative to the probe.11-25-2010

20080267079Network-wide clear channel assessment threshold - Overall network throughput may be increased in a wireless network through a common network-wide clear channel assessment (CCA) threshold. Each access point performs measurements, and determines suitable CCA thresholds and throughput estimates for each data rate. Results are reported to a central controller that determines the network-wide CCA threshold. The network-wide CCA threshold is then used by all access points and mobile stations.10-30-2008
