ASTRI is developing an image analytics platform for digital pathology. It is based on a scalable medical image database, distributed parallel computing engine, and a powerful application development environment for Computer-Aided Diagnosis (CAD). The platform can support efficient management of medical image data. It also facilitates reliable web-based digital pathological information exchanged in telediagnosis and agile development of CAD applications.

ASTRI has established a family of low power ADC IPs.
12/14 bit low power Successive Approximation Register (SAR) ADC delivers low power and low cost analog to digital conversion of reasonable performance for portable medical and sensor devices. ASTRI’s IP is already in mass production for various applications.
24-bit sigma delta ADC is based on sigma delta technology intended primarily for instrumentation applications. It consists of a second-order three-bit quantizer noise shaping modulator and digital decimation filter.
Low input-referred noise: 1.5uVrms
Multi-bit feedback DAC with Data-Weighted Averaging to achieve low power consumption
Unity feedforward architecture for low distortion
2nd order modulator loop, stable for full scale input
ASTRI’s uncooled infrared micro-bolometer readout IC is a high resolution, low power consumption and low noise signal sensing IC for deployment in thermograph applications, such as night vision, surveillance and medical imaging, which require high resolution imaging capability.
640 x 480 pixel focal plan array
Pixel pitch = 20um x 20um
Uncooled operation (with or without thermo-electric cooler)
Adjustable integration time
Adjustable integration capacitors
2 analog outputs available
Digital selection mode via SPI
Power consumption < 360mW (without thermo-electric cooler)
The smart reflective pulse oximeter for remote health monitoring was licensed to several tier-one healthcare manufacturers in Hong Kong and the Mainland for integration into their products, including a wristwatch for measuring vital signs such as body temperature, pulse rate, pulse oximetry and electrocardiogram which has been launched into the market
The device was also installed in the Hong Kong Housing Society Elderly Resources Centre as one of the technologies used to realize intellectual housing for the elderly. With its elderly-friendly design, the device helps the seniors to check their health condition in a comfortable and convenient manner.
A portable embedded optical device for non-invasive blood glucose measurement which can be easily used to measure blood glucose instantly and non-invasively is being developed. This device can be used for screening of pre-diabeters and frequent blood glucose measurement of diabetes patients.
A device to facilitate early detection and screening of elderly with cognitive health problems and also assessing the stress level of general public is being developed. This device can be used for early detection and continual monitoring of cognitive impairment, as well as to improve the experience and ease of cognitive assessment for the elderly in Hong Kong.
A revolutionary cardiovascular monitoring device using smart sensor to measure blood pressure, arterial stiffness and heart rate at wrist has been developed. Unlike traditional cuff-based blood pressure meter, this new device does not block blood vessel during measurement and hence allows continual measurement. The measurement results can be conveniently uploaded to a central database through tele-care systems available in Hong Kong or mobile devices to facilitate health monitoring by medical professionals.
