China, October 28, 202 - LeadingOpticalSolution Supplier Amy Sirang (Six: AMS) The 32-layer solution to the computer fault (CT) scanner is launched, expanding itssensorChip product combination. CT equipment is widely used in numerous areas such as medical, industrial or security. In all of these applications, the detector is the determination factor that can develop a cost-effective CT scanner. Jose Vinau, the Diston Department of Ai Mes, Siram, said: "Amy Si Lurang's AS5951 sensor chip can simplify detector components. It will high sensitivity photodiode arrays and readCircuitIntegrated in a single CMOS chip. As compared to the previous generation, the AS5951 can provide a higher resolution of the same sensor area. "

due toADCAnd the photodiode array is integrated in a single component in a single-chip in a single component, and the sensor chip enables an easy-to-integrated system solution.

Next generation sensor chip

Compared with the previous generation AS5950, a new generation of products mainly increases spatial resolution of the same detector coverage. The sub-millimeter-based equivalent pixel spacing improves the resolution of the image. The photodiode array of AS5951 is composed of 16 x 8 pixels having a spacing of 0.98 x 0.98 mm2, which is improved compared to 0.98 x 1.96 mm2 spacing of the previous generation. Therefore, two AS5951 sensors can be used to achieve a 32-layer detector with a total size of 31.23 mm, and a spatial resolution is doubled. To meet higher pixel density requirements, A / D converter (ADC) The number of channels is increased from 64 to 128. The pixel size can be customized in a shorter development cycle to meet customer needs.

Ai Mes Oshrand's AS5951 provides high resolution images for computer tomography for medical and security fields

Another factor affecting image performance is the low darkness of the maximum 1 pa.CurrentThis can be achieved by automatically calibrating a zero-defining voltage near the photodiode. This parameter is 90% lower than the AS5950 and can achieve better low dose performance. Input-related noise performance is a key factor affecting image quality. Since the connection between the photodiode and the ADC channel is short, the noise performance of the AS5951 is very low, and low dose performance can be improved.

AS5951 has two operating modes: high resolution mode and low dose mode. In high resolution mode, when the input current range is 200 Na, the maximum noise is 0.30 Fc. In low dose mode, when the noise level is 0.43 fc, two pixels combine into a larger pixel, thereby improving signal-to-noise specific performance, and reduces dose levels. The high linearity of ± 600 ppm (including photodiodes) can also ensure an inhautable image. The shortest integration time (200 μs) allows the CT detector to quickly rotate. Digital data can be passed by SPiinterfaceAccess reading.

AS5951 is a cost optimization solution for 32-layer CT detector

Amiis Osram has been patented product design allows 128 channel ADCs to be integrated into a single device in a single-chip, rather than as a discrete device is placed next to the photodiode array. This simplifies the design and reduces the manufacturing cost of the CT detector supplier. When assembling a large pixel array of CT detectors, the AS5951 can be mounted on three adjacent edges of the detector. Two AS5951 ICs can be placed in the Z axis to help develop 32-layer detectors suitable for price-sensitive CT detectors. The internal reference voltage is provided, so there is no need to use an external component to reduce the cost of material. integratedTemperature SensorMonitor the chip temperature. With AS5951, customers can get an off-the-shelf sensor chip solution that simplifies the integration of system and detectors.

In addition, in low dose mode, the maximum power consumption of each sensor is 67.2 MW, which can reduce the self-heating effect, thereby reducing cooling cost.When producing CT modules, they can be used.weldingProcess is directly installed in the AS5951Substratesuperior.In addition, the AS5951 uses a low-cost substrate material to become a cost-effective module solution suitable for CT detectors.This is promoted in a global scaleCT imagingThe diagnostic method is critical.
