Medical Imaging

High-speed and ultra-low noise detector solutions enable manufacturers of Computer Tomography (CT) scanning equipment to produce motion-free CT images while exposing patients to low doses of radiation. The development by ams of innovative detector technologies means that medical professionals can work with clearer pictures and deliver better patient care.

AS5900

The AS5900 device is a low noise, 128-channel current-to-digital converter that enables the readout of the photodiodes with highest sensitivity. High-resolution CT imaging can be achieved up to 26-bits resolution. Its 128-low-noise and high linear converter channels provide an increased gray scale, improved contrast and reduce artifacts of 3D CT images. The low power consumption of 1mW per channel reduces self-heating effects and the overall power consumption of the system. An integrated temperature sensor allows the calibration of temperature drifts of the X-ray detector modules.

Vital Sign Sensing

The biometric sensors product family features first-of-its-kind integrated optical sensor modules which include algorithms for heart-rate measurement, photoplethysmography (PPG) and electrocardiography (ECG). The modules are ideal for a wide range of end products including wearable devices, medical monitors, industrial equipment and mobile devices. Biometric sensors from ams are able to achieve the highest accuracy ratings in the industry because of a combination of a low-noise analog and optical front-end and custom ams software and algorithms. Drawing on expertise in optical sensing in mobile devices, ams provides OEMs with electrical, mechanical and optical design guidelines to enable designers to quickly realize a successful implementation.

AS7000

The AS7000 solution contains the AS7000 module including the LEDs, photo-sensor, analog front-end (AFE) and controller as well as application software required to implement an accurate optical HRM/HRV fitness band product. The module also enables skin temperature and skin resistivity measurements by providing interfaces to external sensors. The AS7000’s low power design is particularly well suited to application in fitness bands, smart watches and sports watches, in which board space is limited and in which users look for extended, multi-day intervals between battery recharges.

AS7024

The operation of the AS7024 is based on photoplethysmography (PPG) and electrocardiogram (ECG). PPG is the most used HRM method which measures the pulse rate by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. ECG is the reference for any measurement of the bio potential generated by the heart. The AS7024 is supported by algorithms converting the PPG and ECG readings into digital HRM, HRV and Blood Pressure values. The module includes the LEDs, photo-sensor, analog front-end (AFE) and sequencer as well as application software. In addition to HRM/HRV and Blood Pressure, the module also enables skin temperature and skin resistivity measurements by providing interfaces to external sensors. The AS7024’s low-power design and small from factor is particularly well suited to application in fitness bands, smart watches, sports watches and smart patches, in which board space is limited and in which users look for extended, multi-day intervals between battery recharges.
