C10900D_15 Datasheet, PDF (1/10 Pages) Hamamatsu Corporation – Flat panel sensor

Flat panel sensor
C10900D
Four selectable scan modes
Photodiode area: 124.8 × 124.8 mm
The C10900D is a flat panel sensor developed for CT and panoramic imaging. It operates in 4 selectable scan modes to capture
X-ray images: “Fast mode” and “Partial mode” with a pixel size of 200 × 200 μm, and “Fine mode” and “Panoramic mode” with
a pixel size of 100 × 100 μm. A single C10900D serves as the X-ray sensor for both CT and panoramic imaging.
Features
Four selectable scan modes with different number of
active pixels and pixel sizes
High-speed imaging: 280 frames/s (Panoramic mode)
High sensitivity: 6000 LSB/mR
Wide dynamic range
Active area: Approx. 12 × 12 cm (1248 × 1248 pixels)
13-bit digital output (Fast mode, Partial mode)
For assembly into equipment (supplied without case)
Applications
Cone beam CT
Digital radiography, etc.
Structure (Fast mode)
The C10900D is comprised of a sensor board and a control board. Mounted on the sensor board is a CMOS image sensor chip made up of a two-
dimensional photodiode array, row-scanning vertical shift register, and 8 charge amplifier arrays. Each charge amplifier array has a horizontal shift
register and consists of 78 ch charge amplifiers with CDS circuit.
CsI scintillator is directly deposited on the two-dimensional photodiode array. X-rays incident on the scintillator are converted to fluorescence,
which then enters the two-dimensional photodiode array where electric charge is accumulated in each pixel according to the light intensity.
The accumulated charge on each row is sequentially selected by the row-scanning vertical shift register, transferred to the amplifiers through
the data line, and converted to a voltage signal. Then an analog signal is sent out from each amplifier array by scanning the horizontal shift
register.
The control board converts the analog signal into a 13-bit digital signal, which is then sent to a frame grabber board as a 13-bit parallel output
through one port.
This product is bare board type for installation into equipment and is not covered with a metal shielded case. See “Notice” for details on EMC.
