 Active Mode:
Active mode is C-Scan
®
Cap main mode of operation. Only in Active mode the C-Scan
®
Cap can perform scans and transmit acquired data.
X-ray transmission occurs only while the C-Scan
®
Cap is in motion inside the colon,
limiting radiation exposure. To detect C-Scan
®
Cap motion, the C-Scan
®
Cap generates a
positioning signal, which is interpreted by the C-Scan
®
Track Scan Control Algorithm which
then informs the C-Scan
®
Cap to open the concealment cover and begin the scan. When
the C-Scan
®
Track determines that the motion has ended, the C-Scan
®
Cap's X-ray source
is concealed.
The C-Scan
®
Cap verifies that the X-ray source is concealed. If there’s a suspect for the
X-ray source not being concealed, the C-Scan
®
Cap sends a message to the C-Scan
®
Track informing it that the X-ray source is exposed. If the issue is not resolved by the
system, the C-Scan
®
Track indicates a malfunction to the subject, who should contact the
clinic immediately.
10.6.2 C-Scan
®
Track
The C-Scan
®
Track is an external device attached to the subject back. The C-Scan
®
Track
tracks the C-Scan
®
Cap position, sends commands to the C-Scan
®
Cap, receives and
stores imaging data sent by the C-Scan
®
Cap, and interfaces at the end of the procedure
with the C-Scan
®
View.
The C-Scan
®
Track has several main modes of operation:
 Idle mode- includes sleep mode
 Calculation cycle mode- a single process of C-Scan
®
Cap position estimation and full
SCA calculation
 C-Scan
®
Cap temperature/pressure data transfer mode- C-Scan
®
Cap sensor data is
received through RF
The C-Scan
®
Track consists of the following units:
 Positioning System - a localization device that tracks and records the position and
orientation of the C-Scan
®
Cap, enabling intra-colon mapping for the purpose of colon
surface imaging.
 Data Recorder - a recording device, which captures the C-Scan
®
Cap data (imaging,
etc.) to a non-volatile memory. Data transmission is through RF communication during
the C-Scan
®
Cap transition in the GI tract.
 Processing Unit – an embedded device that controls localization and recording
functions, running an embedded Scan Control Algorithm through which the C-Scan
®
Cap’s scan mechanism is operated.
 User Interface Unit –Provides status indicators to the subject and operator.
