During a procedure, interventionalists have to see clearly – while keeping dose as low as possible. As your partner for minimally invasive interventions, we have made it our mission to further drive technology to empower you to tap your full potential. Following our tradition of innovation, we took an initiative to redefine the principles of automatic exposure control and rebuilt it from the ground up – resulting in our imaging solution OPTIQ. Based on big data, OPTIQ delivers constant image quality throughout a procedure, independent of angulation or patient size1, while also significantly reducing dose. Find out more about OPTIQ and how it supports you in expanding precision medicine.
OPTIQ - constant image quality in support of ALARA3 dose
With increasing patient attenuation, the conventional detector-dose-driven exposure control leads to a reduction of image quality – even in the average patient thickness range between 20 – 30 cm.
Our newly developed exposure control OPTIQ uses a contrast-based technique, supported by intelligent, self-adjusting algorithms. It automatically considers SID, collimation settings, grid status, and patient thickness – and finds and applies the best suitable combination of the 5 radiation exposure parameters and the detector dose as an additional variable. This new exposure control constantly aims to achieve the requested contrast-to-noise ratio at the lowest possible dose.
The basis for this complex functionality is a vast database containing 300 million entries. With every image acquisition, the system checks up to 15,000 possible parameter combinations with the goal to select the most dose-efficient one for a specific imaging situation.

Structure Scout – optimized visibility of details and devices
For interventional procedures, devices like guide wires, coils, and stents are indispensable. The market is constantly growing, with new devices emerging made from different materials – and each one needs to be clearly visible without an increase in dose.
Structure Scout automatically optimizes the visibility of different devices and materials, based on their individual dose absorption property. This material-specific imaging is based on preset values. As a result, the system automatically adapts its exposure control parameters to the material used.

OPTIQ Roadmap: Significant improvements of device contrast over vessel map
“Impressive is the quality of the Fluoroscopy and the quality of the Roadmap. Increased image quality goes together with a reduction in doses.”4

Within physical limits
Dose reduction (based on phantom measurements) compared to conventional automatic exposure control - e.g., available with Artis Q, image quality is defined by contrast-to noise ratio
ALARA = As Low As Reasonably Achievable
The statements by Siemens Healthineers customers described herein are based on results that were achieved in the customer's unique setting. Because there is no “typical” hospital or laboratory and many variables exist (e.g., hospital size, samples mix, case mix, level of IT and/or automation adoption) there can be no guarantee that other customers will achieve the same results.
