OPTICAL SCANNING - A NEW LIGHT IN DIAGNOSTIC BREAST IMAGING

Dynamic Optical Breast Imaging (DOBI) is a low cost, non-invasive optical mammographic technique to obtain physiological information on angiogenesis in breast tissue. Angiogenesis reflects the potential aggressiveness of malignant lesions.

Slight pressure is applied to the breast (10mmHg) and near-infrared light (640nm) from an array of light emitting diodes (LED) is used to illuminate the breast.  A camera system records several images per second of the light transmitted through the breast tissue for approximately 45 seconds.  Light absorption by the tissue varies according to the haemoglobin/deoxyhaemoglobin ratio.  A software application generates colour breast images that map the relative concentrations of deoxyhaemoglobin in the breast tissue and thus permit evaluation of vascularity.

ComfortScan is a DOBI device that can be used in mammography screening procedures, symptomatic breast imaging and follow-up imaging (symptomatic). Its use is particularly recommended for examinations of younger patients.

Examination

  • Comfortable and quick
  • Non-radiographic therefore non-invasive

Scanning

  • Real time, high resolution data acquisition
  • Using monochromatic red light and a proprietary image processing algorithm

Connectivity or Versatility

  • The imaging platform can be enhanced and used in conjunction with other diagnostic systems, including conventional and digital mammography (FFDM), ultrasound and MRI

Unparalleled Advantages

Dynamic Optical Image

  • Extremely sensitive to light absorption variations in pressure stimulated blood vessels

Angiogenesis Highlighting

  • Visualisation of the abnormal vascular bed. Results in a reduction in diagnostic ambiguity

Gentle Compression

  • Sufficient pressure to detect the angiogenesis (only up to 10mmHg)

High Intensity LED's

  • A sophisticated optical system optimises the light intensity to the different breast densities creating diagnostic images without ionizing radiation

Rapid Scanning Time

  • Images acquired in less than 1 minute

Examinations

  • Examinations can be made from the age of 18 to provide very early breast tumour diagnosis

Tumour Angiogenesis Nutrient Supply for Tumour

Highly advanced vascular investigation providing a timely diagnosis to enable early treatment.

History

  • In 1994 the Angiogenesis Foundation identified angiogenesis as the "common denominator" in many important diseases, including breast tumour

Research

  • Proves that a breast tumour becomes clinically relevant once it develops a blood supply vascular network

Early vascular detection

  • Subtle vascular changes are often associated with breast cancer in its earliest stages

Advanced Performance Technology

  • Detects the vascular changes and defines a unique vascular profile indicating the early development of a tumour angiogenesis

Pre-Angiogenesis Tumour

Early Stage Angiogenesis

Advanced Angiogenesis

Needs a blood supply to grow.
More nutrient vessels often result
in more aggressive growth.

Capillary vessel growth often promotes rapid tumour
development

A dense network of blood vessels fuels the tumour growth
