USB 3.0 Camera

The Lt425 and Lt225 from Lumenera Corporation (Ottawa, Ontario, Canada) use USB 3.0 technology to deliver images up to 170 fps. Image captures, complemented by 128 MB of onboard memory, can be synchronized using either a hardware or software trigger. Images are temporarily held within the camera until the host computer is ready to receive them. The camera, measuring 40 × 40 × 53 mm, features 4 mounting points on all 4 sides. The fully locking USB 3.0 cabling and digital interface ensure a plug-and-play installation. No framegrabber is required.

Zoom Lens

The Model 207 Motorised Mini Zoom Lens from Resolve Optics Ltd. (Chesham, UK) focuses on an object at infinity down to an object positioned 35 millimeters in front of the lens. The Model 207 (50 x 34 x 31 mm) is designed for use with miniature CCTV cameras in applications including industrial inspection and control, surveillance, robotics, and scientific analysis. Using the close focus capability of the Model 207 f/2.8 zoom lens allows an object to be shown in detail on a TV monitor.

Instantly Capture, Edit, and Store Medical Images via Online Applications

Online tool allows user to conveniently capture and manage images from medical devices. A new image capture software development kit (SDK), called the Dynamic Web TWAIN, allows the simplified creation of an online tool to manage images of patient records. It enables image application providers to deliver a method to capture images from medical devices, such as intraoral cameras and digital x-ray equipment, and then send the medical images to a central web server. Such medical image captures can be sent alongside a patient’s identification, results data, applied treatments, next visit schedules, and more. An SDK allows implementation within popular Internet browsers, including Internet Explorer, Chrome, Firefox, Safari, or Opera. (See Figure 1)

The Eyes of the Mars Curiosity Rover

On August 6, 2012, the Mars Curiosity rover successfully landed on the floor of Gale Crater on Mars. The Curiosity rover is about the size of a small SUV — 10 feet (3 meters) long, not including the arm, 9 feet (2.7 meters) wide, and 7 feet (2.2 meters) tall.

‘Soft X-Ray’ Detector Could Improve Breast Cancer Imaging

New X-ray technology minimizes harmful exposure and allows better breast imaging. While clear imaging is extremely important in diagnosing breast cancer from mammograms, there is also concern about exposing the patient to too much radiation from repeated X-rays. But that may soon change, says Krishna Mandal, an associate professor of electrical engineering at the University of South Carolina (USC), Columbia, who led the team that built a new type of Xray detector that offers tremendous potential in breast cancer detection and treatment.

Hands-Free Transcranial Color Doppler Probe

These probes enable full use of TCD technology for neurological diagnostics. Current transcranial color Doppler (TCD) transducer probes are bulky and difficult to move in tiny increments to search and optimize TCD signals. This invention provides miniature motions of a TCD transducer probe to optimize TCD signals.

Non-Invasive Instrument for Skin Cancer Screening

Andor Newton camera powers combined RS-OCT probe capable of both morphological and biochemical characterization of skin cancers. Skin cancer is the most common form of cancer in humans, with annual rates continuing to climb from their current estimate of just over three million new cases each year. Although all skin cancers share the likelihood of a favorable outcome if early diagnosis and complete resection are achieved, diagnosis is invasive, subjective, lengthy, and expensive, as it involves expert visual inspection, biopsy, and histopathology.

3D Visualization in Geospatial Analysis

The past decade has seen an explosion of observations from airborne and satellite-based multiand hyperspectral sensors, as well as from synthetic-aperture radar and LiDAR. Distilling useful information from this wealth of raw data is the domain of geospatial analysis, the collection of analytical, statistical, and heuristic methods for extracting information from georeferenced data. This information is important in serving the needs of a diverse set of industries including environmental conservation, oil and gas exploration, defense and intelligence, agriculture, coastal monitoring, forestry, and mining.
