ams OSRAM is a leader in computed tomography and digital X-ray sensors for medical imaging. We design and manufacture unique medical image sensing solutions which offer outstanding precision, high acquisition speeds, low noise and ultra-low power consumption. This enables manufacturers of scanning equipment to produce sharp images while exposing patients to the lowest possible doses of radiation.
A CT scanner is one of the most powerful diagnostic tools available to medical practitioners because of its very fast acquisition times for 3D images of various parts of the human body: bones, skeletal muscles, head, heart or lungs. It achieves a high contrast ratio between bone, tissue, blood vessels and other parts of the body.
A key component of a modern multi-slice CT scanner is the detector array: this senses the X-ray radiation which is partially attenuated by tissues in the patient’s body and converts them into a digital signal. The design of the detector array affects its operating characteristics, such as sensitivity, noise, resolution and speed.
ams OSRAM takes its leading image sensing expertise forward to achieve an unprecedented level of image quality at lowest possible doses, also referred to as photon counting technology. We offer a wide range of high-performance solutions addressing both three-side and four-side buttable options, exhibiting low noise, ultra-low power, and high readout speeds.
Such solutions range from stand-alone high channel count analog-to-digital converters allowing maximum flexibility for our customers, to highly integrated ICs combining both photodiode arrays and readout circuits in a single silicon package, driving ultimate performance. Fast acquisition speeds and best in class signal-to-noise ratio allows to lower the exposed X-ray radiation doses to its physical limits, which translates for the patients into significant less stress on their body.
In order to achieve best possible image quality ams OSRAM provides complementing portfolio options for precise patient positioning adjustments. Besides narrow focus laser and LED products, or fully integrated projection solutions for optical guidance and alignment for best-possible patient placement. ams OSRAM offers precise linear and angular position sensors to steer the supporting mechanical equipment with highest positioning accuracy. Supporting 2D or 3D camera based vision solutions or time-of-flight based 3D sensing might be considered to enable algorithmic compensation of small movements by the patient while being CT scanned. This is important because patients who are not positioned correctly can cause difficulties in the distribution of the radiation dose and resulting image quality might not be optimal.
