Abstract: Methods for capturing and transmitting images by an in-vivo device comprise operating a pixel array in a superpixel readout mode to capture probe image, for example, according to a time interval. Concurrently to capturing of each probe image, the probe image is evaluated alone or in conjunction with other probe image(s), and if it is determined that no event of interest is detected by the last probe image, or by the last few probe images, the pixel array is operated in the superpixel readout mode and a subsequent probe image is captured. However, if it is determined that the last probe image, or the last few probe images, detected an event of interest, the pixel array is operated in a single pixel readout mode and a single normal image, or a series of normal image, is captured and transmitted, for example, to an external receiver.

Abstract: Systems and methods for monitoring of physiological signals together with subject awareness information, including measuring and analyzing blood pressure and contextual blood pressure analysis of subjects. Systems and methods of non-invasive (optionally continuous or waveform) blood pressure measurement of subjects with sensor-derived data such as subject's activity, posture, location, place, time, etc.

Abstract: A method of deriving one or more individual thoracic parameters of a subject. The method comprises instructing a subject to perform a thoracic volume manipulation, receiving a plurality of measurements of a plurality of EM signals from a thoracic intrabody area of lungs of the subject during the thoracic volume manipulation, deriving a plurality of thoracic volume values at a plurality of different intervals during the thoracic volume manipulation so that each the thoracic volume value correspond with another of a plurality of estimated thoracic volumes achieved during the thoracic volume manipulation, and calculating at least one individual thoracic parameter of the subject by combining between the plurality of measurements and the plurality of thoracic volume values.

Abstract: A novel and useful system and method for generating user feedback related to the quality of the placement and contact of a blood pressure sensor on a user's body. The sensor is incorporated in a wearable blood pressure measurement device that is capable of analyzing and providing feedback regarding the quality of placement and contact of the pressure sensor array. The wearable includes a pressure sensor array for monitoring blood pressure, means for attaching the pressure sensor to a user's body for measuring a region, a processor operative to record pressure signals from said sensor array and to calculate quality of pressure sensor contact to measurement area score, and a display operative to determine and display the quality of the placement and contact of the pressure sensor. A quality metric indicating the quality of the placement and contact of the pressure sensor is provided as feedback to the user.

Abstract: Information indicative of multiple regions of the anatomy of a patient (602, 604, 606), such as one or more of the head, neck, chest, abdomen, or pelvis, is obtained in a single scan. A plurality of studies (32) are generated. Each study definition includes a region of the patient's anatomy (602, 604) and a study protocol. Each study (32) includes (48) images generated using information from the scan and the value of the imaging parameter.

Abstract: A technique for use in angiography includes obtaining data from a tracking scan following injection of a contrast agent according to a test injection profile. A region of interest (308) is established. The data from the tracking scan, the test injection profile, and the measured enhancement of the region of interest (302) are used to establish a patient function at the region of interest. The patient function and a desired enhancement profile (402) are used to establish a desired clinical injection profile. The desired clinical injection profile is communicated to a contrast injector (36) via an electrical injector interface.

Abstract: A method for modeling a spine, comprising providing at least one image of the spine, extracting a plurality of anatomical elements of the spine from the at least one image, and constructing a model representing the anatomy of the spine using the anatomical elements.

Abstract: A current diagnostic image and an archived diagnostic image of a common region of patient are loaded into a first memory (14) and a second memory (18). The diagnostic images are converted into feature images (24), scaled (40), and normalized (42). An affine transform determining processor (50) generates an affine transform representative of the error between the current and archived images. A transform operator (90) operates on one of the diagnostic images in accordance with the affine transform to bring the two images into registration. A display processor (104) displays corresponding pairs of slices of the registered first and second images on a monitor (22). A stepping processor (102) causes the displayed slice pairs of the registered images to be stepped together in coordination.

Abstract: There is provided a method of medical imaging of a structure that includes creating a three dimensional image of the structure and processing the image to enhance image quality such that images with an attenuation value below a threshold value result in recognizable image, thereby identifying the structure.
