Use of electromagnetic radiation to produce images of internal body structures for diagnosis. X-rays have been used since 1895. Denser tissues, such as bones, absorb more X-rays and show as lighter areas on X-ray film. A contrast medium can be used to highlight soft tissues in still X-ray pictures or can be followed on X-ray motion-picture films as it moves through the body or part of the body to record body processes. In computerized axial tomography, X-rays are focused on specific tissue planes, and a series of such parallel "slices" of the body are processed by computer to produce a 3-D image. The risks of X-ray exposure are reduced by more precise techniques using lower doses and by use of other imaging techniques.

Imaging Diagnostic Systems, Inc. ( ‘IDSI') is a development stage medical technology Company. The Company is engaged in the development and testing of a Computed Tomography Laser Breast Imaging System for detecting breast cancer (CT Laser Mammography or, ‘CTLM(r)'). The CTLM(r) system is a CT-like scanner, but its energy source is a laser beam and not ionizing x-radiation such as is used in conventional x-ray mammography or CT scanners. The advantages of imaging without ionizing radiation might be in markets. CTLM(r) is an emerging new imaging modality offering the potential of molecular functional imaging, which could visualize the process of angiogenesis which might be used to distinguish between benign and malignant tissue. X-ray mammography is a well-established method of imaging the breast but has limitations especially in dense breast cases. Mammography is an x-ray imaging modality commonly used for both routine breast cancer screening and as a diagnostic tool. Digital mammography, also referred to as ‘full-field digital' mammography, is the latest form of breast x-ray examination. These systems eliminate the use of x-ray film and record images directly on electronic panels. Magnetic resonance imaging (‘MRI') produces images using a magnetic field and radiofrequency (RF) gradients under computer control to produce proton density images. Ultrasound imaging is routinely used in breast imaging practices. Ultrasound systems could image breast tissue by ‘sonar' techniques. Sound transducers are placed directly on breast tissue coupled with an acoustic gel substance. The CTLM(r) laser breast imaging system is being marketed as an adjunct to mammography and would not compete directly with X-ray mammography. Fluorescence and molecular imaging techniques are of growing importance to the drug development industry and for disease detection. The Company's Laser Imager for Lab Animals ‘LILA(tm)' program is an optical helical micro-CT scanner in a third-generation configuration. The LILA scanner is targeted at pharmaceutical developers and researchers who monitor cancer growth and who use multimodality small animal imaging in its clinical research. It is subject to numerous federal, state, and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, and fire hazard control.
