Purpose: The development of computer-aided diagnostic (CAD) methods for lung nodule detection, classification, and quantitative assessment can be facilitated through a well-characterized repository of computed tomography (CT) scans. The Lung Image Database Consortium (LIDC) and Image Database Resource Initiative (IDRI) completed such a database, establishing a publicly available reference for the medical imaging research community. Initiated by the National Cancer Institute (NCI), further advanced by the Foundation for the National Institutes of Health (FNIH), and accompanied by the Food and Drug Administration (FDA) through active participation, this public-private partnership demonstrates the success of a consortium founded on a consensus-based process. Methods: Seven academic centers and eight medical imaging companies collaborated to identify, address, and resolve challenging organizational, technical, and clinical issues to provide a solid foundation for a robust database. The LIDC/IDRI Database contains 1018 cases, each of which includes images from a clinical thoracic CT scan and an associated XML file that records the results of a two-phase image annotation process performed by four experienced thoracic radiologists. In the initial blinded-read phase, each radiologist independently reviewed each CT scan and marked lesions belonging to one of three categories (" nodule≥3 mm," " nodule<3 mm," and "non- nodule≥3 mm "). In the subsequent unblinded-read phase, each radiologist independently reviewed their own marks along with the anonymized marks of the three other radiologists to render a final opinion. The goal of this process was to identify as completely as possible all lung nodules in each CT scan without requiring forced consensus. Results: The Database contains 7371 lesions marked "nodule" by at least one radiologist. 2669 of these lesions were marked " nodul≥3 mm " by at least one radiologist, of which 928 (34.7%) received such marks from all four radiologists. These 2669 lesions include nodule outlines and subjective nodule characteristic ratings. Conclusions: The LIDC/IDRI Database is expected to provide an essential medical imaging research resource to spur CAD development, validation, and dissemination in clinical practice. © 2011 U.S. Government.


A system and method for planning volumetric treatment by percutaneous needle procedures obtains a volumetric image data set of a subject including an identifiable region requiring treatment. An effective treatment volume is defined relative to the needle position for at least one needle carrying a treatment applicator. One or more proposed inserted needle position is defined such that a effective treatment volume corresponding to the one or more proposed inserted needle position provides coverage of the region requiring treatment. The effective treatment volume for one or more needles can then be visualized in the context of slices of 3D image data. One or more entry point and corresponding virtual target are then defined relative to a frame of reference of the volumetric image data set for use in navigation of the at least one needle to the corresponding proposed inserted needle position.

The novel optical tracking system employs a miniature video camera, mounted on the hub of an interventional needle, to determine the location and orientation of the needle relative to a skin-attached sticker with color reference markers. A computed tomography (CT) scan is used to register the same reference markers to the anatomy in the CT images, and thus, register the needle to the anatomy and to a user-selected target. A computer displays a simulation of the interventional needle on the CT images, providing guidance information to assist a user in directing the needle to the target. Bench testing was performed on a custom phantom to determine the accuracy of this minioptical tracking system. The resulting accuracy data demonstrate a good correlation with phantom coordinates and the CT images. © 1964-2012 IEEE.

ActiViews raises $5M for medical-imaging systems — Israel’s ActiViews, a developer of technology for enhancing MRI and PET scans, raised $5 million in a first funding round. Investors included Ofer Hi Tech and Evergreen Venture Partners. ActiView’s system provides real-time analysis of medical images used to guide invasive surgical procedures. Current practice often requires multiple scans, which are expensive and involve radiation exposure that can cause further harm. ActiView’s technology is designed to reduce the number of scans required to locate tumors for biopsy or removal. Cambridge Major Laboratories acquires ChemShop — Cambridge Major Laboratories, a Germantown, Wisc., provider of outsourced chemistry services to the pharmaceutical industry, acquired ChemShop of the Netherlands. The release is here. The companies didn’t disclose terms of the deal. The combined company will have 140 employees at three sites in the U.S. and Europe. Freedom-2 raises $5.4M for removable-tattoo inks — Freedom-2, a Cherry Hill, N.J., developer of permanent but easily removable tattoo inks, pulled in $5.4 million in a second round of funding raised by its holding company, Freedom-2 Holdings. Independent investors provided the funding. The company’s Infinitek ink system uses bioabsorbable pigments that are encapsulated in microscopic polymer beads. Tattoos inked with the system are permanent, but easily removable by laser treatment htat breaks the beads, allowing the body to reabsorb the pigment.
