A wireless network having an architecture that resembles a peer-to-peer network has two types of nodes, a first sender type node and a second receiver/relay type node. The network may be used in a medical instrumentation environment whereby the first type node may be wireless devices that could monitor physical parameters of a patient such as for example wireless oximeters. The second type node are mobile wireless communicators that are adapted to receive the data from the wireless devices if they are within the transmission range of the wireless devices. After an aggregation process involving the received data, each of the node communicators broadcasts or disseminates its most up to date data onto the network. Any other relay communicator node in the network that is within the broadcast range of a broadcasting communicator node would receive the up to date data. This makes it possible for communicators that are out of the transmitting range of a wireless device to be apprized of the condition of the patient being monitored by the wireless device. Each communicator in the network is capable of receiving and displaying data from a plurality of wireless devices.

A method for processing partial lines of image data from a detector, each partial line of data representing a portion of an image pixel matrix, includes: (a) communicating partial lines of image data over a network from an imaging system to a remote facility; (b) receiving partial lines of image data in a first sequence; (c) assigning to each partial line of image data in a first series a position in a second sequence by reference to a plurality of base addresses; (d) altering the base addresses; and (e) assigning to each partial line of image data in a second series a position in the second sequence by reference to the altered base addresses.

Method and apparatus for processing partial lines of scanned images and communicating associated data over a network

Partial lines of data representative of adjacent pixels in an image pixel matrix are reordered to facilitate reconstitution of a scanned image. The partial lines are received by a signal processing circuit and are assigned unique addresses by reference to base address and offset values. Each partial line is then stored in a memory address corresponding to the assigned address. The values of the base addresses and offsets may be altered to accommodate different image matrix sizes and scanning patterns.

A method for detecting cut data lines in an imaging array having a detector including an array of pixels for measuring radiation, and a plurality of data line contacts is provided. The method includes the steps of initializing pixels of the imaging array which includes a plurality of data lines including at least one uncut data line and at least one cut data line, wherein each cut data line is electrically connected to at least one of the plurality of data line contacts and at least one uncommitted contact. The method further includes determining a signal level for the uncut data lines, measuring a signal level of each data line in the plurality of data lines, and determining a number of cut data lines and a number of uncut data lines by using the signal levels received from each data line in the plurality of data.

A method and an apparatus for increasing the apparent acoustic frame rate of ultrasound images. Frames of acoustic data are acquired at the acoustic frame rate, stored in double-buffered acoustic frame buffers and scan converted one after the other. For each pair of successive frames, the first acoustic frame is stored in a frame delay buffer while the other acoustic frame is being scan converted. In accordance with this scheme, the scan converter is always reading from an acoustic frame buffer that contains a single complete frame of acoustic data, thereby eliminating the swirl artifact. To increase the apparent acoustic frame rate, the scan-converted acoustic data is input to a scan-converted frame interpolator, which incorporates the frame delay buffer, a frame interpolator programmable read only memory (PROM) and a software-programmable inter-polator bank select look-up table. The frame interpolator PROM incorporates a two-point FIR filter which outputs a frame of interpolated scan-converted acoustic data X.sub.n ' in response to input of the scan-converted acoustic data X.sub.n and X.sub.n-1. A predetermined number of unique frames of scan-converted acoustic data X.sub.n ' can be generated from the acoustic data X.sub.n and X.sub.n-1 of a given pair of frames by changing the weighting factors at the video rate while recycling the scan-converted acoustic data of the given pair of frames.

A color adaptive frame averaging method for an ultrasound imaging system adds persistence to images. The color adaptive frame averaging is achieved by computing filter weighting coefficients and using the filter weighting coefficients to compensate for aliased color data. Frame rate compensation is achieved by adjusting the filter weighting coefficients. In accordance with the present invention, the color adaptive frame averaging method comprises a filter, such as an infinite impulse response filter.
