Planned DOBI System
Dynamic Optical Breast Imaging (DOBI)
Dynamic Optical Breast Imaging (DOBI) system is
a user friendly device for guiding a biopsy recommendation.
Unlike x-ray mammography, the DOBI system utilizes
non ionizing red light as the
Rather than applying high pressures via a hard plate, the DOBI system applies
a lower and uniformly distributed pressure via a
gently inflated soft-membrane breast holder. With low costs of
instrumentation and routine operation, the DOBI system has the potential of providing affordable and
highly effective diagnostic solutions to the US healthcare system and eventually to millions
of women worldwide.
In a DOBI scan, the dynamic physiologic responses of the
breast are effected by a small pressure stimulus. The pressure
of the soft holder and the illumination are automatically controlled by an independently programmed embedded
microprocessor. Pressure level in the soft breast holder is continuously
monitored and accurately maintained by a sensor integrated feedback subsystem.
High repeatability of system performance is supported by synchronized
executions of pneumatic, illumination, and data acquisition subsystems. Fault
tolerant communication commands are exchanged
between the computer and the embedded control unit for both system control
and status feedback. The operation protocols are built on Windows based graphics
interface, and are user friendly. Data acquisition of the system is attained
by a high sensitivity digital camera, which possesses high gain, low readout
noise, and high dynamic range.
In 1998, the DOBI system successfully passed electrical, mechanical,
as well as electromagnetic compatibility (EMC) tests performed by independent
laboratories in accordance with US, European, and Canadian standards. Today,
the DOBI system is a diagnostic instrument with UL, CE, and CUL
