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.

The GigE Vision® Interface Standard: Transforming Medical Imaging

Live, high-resolution imaging is increasingly being leveraged to enhance operating procedures. It can improve the precision of physicians and their instruments, and minimize the invasiveness of many procedures. Increasingly, one small component in a vision system — the interfacing technology — is providing answers to the most common of these challenges.
