Flat panel sensor
C9730DK-10
For soft X-ray imaging, cassette type with USB 2.0 interface
Photodiode area: 52.8 × 52.8 mm
The C9730DK-10 is two-dimensional CMOS image sensor module designed for X-ray imaging which requires high resolution,
large area and wide dynamic range. A target material of X-ray source and X-ray energy adequate for the sensor is Mo and 17
keV. The device shape is thin cassette which incorporates on-chip high-resolution scintillator and a control board. An on-board
USB 2.0 interface can realize fast data transfer to the C9730DK-10.
Features
Applications
High resolution
X-ray imaging (optimized to 17 keV)
1056 × 1056 pixels (50 μm pitch)
14-bit digital output (USB 2.0 interface)
High-speed imaging: 4 frames/s
No dead area (insensitive area) due to seamless structure
Compatible with Hamamatsu API (DCAM-API)
Structure
The C9730DK-10 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 132 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 14-bit digital signal, which is then output to a PC through the USB 2.0 interface.

proper countermeasures such as making periodic image correction.
· This product is warranted for a period of 12 months after the date of the shipment. The warranty is limited to replacement or repair of
any defective product due to defects in workmanship or materials used in manufacture. The warranty does not cover loss or damage
caused by natural disaster, misuse (including modifications and any use not complying with the environment, application, usage and
storage conditions described in this datasheet), or total X-ray radiation dose over 45000 R (390 Gy) even within the warranty period

Description of terms
Blemish
Length of pixel cluster which has less than 90 % of the average sensitivity of the surrounding pixels.
Column
Bright line output adjacent to a defect line
A B C D E F G H I
The relative sensitivity ratio “a/b” should be 120 % or less for both vertical and horizontal
lines, where “a” and “b” are defined as follows:
a: Average sensitivity of bright line (Line A) adjacent to defect line
b: Average sensitivity of standard line (Line B) adjacent to Line A
Row
Note that the average sensitivity of the bright line is calculated from the region adjacent to
the defect region in the defect line.
Example: See the right figure
Defect region in defect line: From pixel (J, 1) to pixel (J, 15)
a: Average sensitivity from pixel (I, 1) to pixel (I, 15) or from pixel (K, 1) to pixel (K, 15)
b: Average sensitivity from pixel (H, 1) to pixel (H, 15) or from pixel (L, 1) to pixel (L, 15)
