A method and system acquiring, processing and displaying breast ultrasound images in a way that makes breast ultrasound screening more practical and thus more widely used, and reduces the occurrence of missing cancers in screening and diagnosis, using automated scanning of chestwardly compressed breasts with ultrasound. Enhanced, whole-breast navigator overview images are produced from scanning breasts with ultrasound that emphasize abnormalities in the breast while excluding obscuring influences of non-breast structures, particularly those external to the breast such as ribs and chest wall, and differentiating between likely malignant and likely benign abnormalities and otherwise enhancing the navigator overview image and other images, thereby reducing the time to read, screen, and/or diagnose to practical time limits and also reduce screening or diagnostic errors.

Signals representative of total photocharge integrated within respective image-sensor pixels are read out of the pixels after a first exposure interval that constitutes a first fraction of a frame interval. Signals in excess of a threshold level are read out of the pixels after an ensuing second exposure interval that constitutes a second fraction of the frame interval, leaving residual photocharge within the pixels. After a third exposure interval that constitutes a third fraction of the frame interval, signals representative of a combination of at least the residual photocharge and photocharge integrated within the pixels during the third exposure interval are read out of the pixels.

Fractional-readout oversampled image sensor

An optical smart sensor combines a phase grating with a rolling shutting to distinguish between modulated point sources. Employing a phase grating in lieu of a lens dramatically reduces size and cost, while using timing information inherent to imaging techniques that used a rolling shutter allows the smart sensor to distinguish point sources quickly and easily using a single frame of image data.

Methods and systems for distinguishing point sources

An imaging system includes multiple diffractive optical gratings disposed over a two-dimensional array of photosensitive pixels. The different gratings present different patterns and features that are tailored to produce point-spread responses that emphasize different properties of an imaged scene. The different responses are captured by the pixels, and data captured from the responses can be used separately or together to analyze aspects of the scene. The imaging systems can include circuitry to analyze the image data, and to support modes that select between point-spread responses, selections of the pixels, and algorithms for analyzing image data.

A method and system for processing and displaying breast ultrasound information is described. A 2D feature weighted volumetric coronal image as a 'guide' or 'road map' is generated from the 3D ultrasound data volume to represent the 3D dataset with the goal of emphasizing abnormalities within the breast while excluding non-breast structures, particularly those external to the breast such as ribs and chest wall.

A method and system for computer-aided detection of abnormal lesions in digital mammograms is described, wherein digital films are processed using an automated and computerized method of detecting the order and orientation of a set of films. In one embodiment, anatomic features are used to detect the order, orientation and identification of a film series. In another embodiment of the invention, a technologist feeds films into the system in any order and orientation. After processing, the system provides an output on a display device to a radiologist that is in an order and orientation preferred by the radiologist. In yet another embodiment of the invention, films from one case are distinguished from films of another case. In this manner and through the use of a bulk loader, a large number of films can be stacked together and fed into the system at one time.

Method and system for automatic identification and orientation of medical images

An image capture device includes a frame buffer, a processor, a shutter, an actuator, a three-axis optical motion sensor and an image sensor. The image sensor defines an optical axis. The three-axis optical motion sensor provides information concerning rotational movement of the camera about each of a roll axis, a yaw axis and a pitch axis. The roll axis is parallel to the optical axis. The yaw axis and the pitch axis are orthogonal to one another and orthogonal to the roll axis. The actuator rotates the image sensor in response to the rotational movement of the device about the optical axis. The processor generates first and second offsets responsive to the rotational motion about the yaw axis and the pitch axis. The processor shifts each line of image information in a frame in accordance with the first and second offsets.

Systems and methods for image stabilization

An optical imaging system with dynamic buffer management is described. Embodiments of the optical imaging system include an image sensor, a buffer, and a buffer mode controller. The image sensor includes a pixel array to read out a plurality of pixel lines for a frame of an image. The buffer is configured to store a plurality of buffer values corresponding to a plurality of pixel values for each of the pixel lines. The buffer mode controller is configured to dynamically switch between an accumulation mode and an averaging mode. The accumulation mode facilitates a computation of each buffer value according to a sum value of the corresponding pixel value and a corresponding previous buffer value. The averaging mode facilitates a computation of each buffer value according to an average value of a normalized value of the corresponding pixel value and the corresponding previous buffer value.
