1 Philips Key advantages including improved image quality and with AC offers improved image quality, interpretative certainty, diagnostic Alternatively, simplify patient care by exposing patients to reduced radiation

2 This proven technology uses a patented matched dual- uniformity. with AC allows for the use of an attenuation corrections in addition to resolution recovery. Incorporating imaging physics into allows reconstructions with fewer counts (via reduced time or reduced dose). has been validated in a multi- Interpretive certainty data reconstructed with enables equivalent interpretive certainty compared with full-count data reconstructed 60 p= Equivocal Better image quality data reconstructed with allows improvements in image quality beyond that provided by full-count data reconstructed using p< Excellent/Good Fair/Poor Excellent/Good Fair/Poor 2

Reducing patient imaging time can help achieve higher throughput. Stress-only protocols are enabled by combining AC by reducing the need for rest imaging in patients with stress studies. Do more with less because half-count imaging and stress-only protocols allow you to maintain diagnostic accuracy while lowering the effect of the rising costs of radiopharmaceuticals on your department's budget p=0.442 p=0.113 p=0.079 Sensitivity Specificity Normalcy 4

5 Focus on patients helps you simplify patient care by allowing you to inject half the dose and imaging at full time, exposing patients to reduced radiation doses while maintaining accuracy. Alternatively, shorter scan times using full injected dose may improve patient comfort and convenience. with AC also may eliminate the need for rest imaging, helping to improve the patient experience.
