Abstract: An input function indicative of a time-activity curve in pulmonary arterial plasma is produced from a series of PET image frames in lieu of manual blood sampling. Two manually acquired blood samples are input along with pixel values of a blood pool region of interest (ROI) in the PET image frames into a two-parameter model of the ROI's time-activity curve. In an iterative process the model converges to accurately indicate the amount of 18F-FDG tracer in the arterial blood. Pulmonary uptake of the tracer is assessed with the PET image frames and the calculated input function.

Abstract: In a tracking method for tracking a local wireless device in a medical facility having a medical facility network (10), the local wireless device (50, 51, 52), which is not connected with the medical facility network (10), is detected based on local wireless communication. (54, 55, 56, 58) between the local wireless device and at least one nearby network device (12, 14, 16) that is connected with the medical facility network. A location of the local wireless device within the medical facility is estimated based on the local wireless communication and information indicative of a location of the at least one nearby network device.

Abstract: The medical communication system comprises a plurality of medical identification devices (12). Each identification device (12) is attached to one particular patient (14). A registration processor generates a unique patient identification data that is stored in an electronic patient identification code memory (54). Each identification device (12) includes an intra-body wireless communication device (16) which transmits the patient's identification on the patient's body. A medical device (22), which is linked to the patient (14) to measure a vital function, periodically automatically receives the patient's identification code to continually ensure association to a correct patient.

Abstract: The invention relates to a method of establishing a wireless communication connection between a source apparatus (20) and the spatially closest target apparatus (12). The source apparatus (20) transmits search signals (21) at an increasing range (Rd), and a communication connection (22) is established with that target apparatus (12) which is the first to be within range of the search signals (21). After the communication connection has been established, the range (Rc) for the actual communication connection (22) is preferably increased. The communication may be realized particularly in accordance with a Bluetooth protocol and may be used in, for example, a patient-monitoring system.
