Download at www.accusoft.com COMPRESSION Image compression and decompression is faster and more effective using a standards-compliant Accusoft software development kit (SDK). When you’re building software to handle medical images and DICOM files, start here. We support multiple image formats on various operating systems. faster more effective compression and decompression for medical images and DICOM files accusoft delivers optimizes standards-based image compression technologies Considered the best supported and most advanced in the industry, PICTools Medical image compression libraries are relied upon within leading PACS, teleradiology, ultrasound, and cardiology applications. This software development kit (SDK) enhances still image and video medical imaging applications. The PICTools Medical SDK contains high performance C libraries providing the fastest compression and decompression engines available. It offers both lossy and lossless DICOM compliant formats, including 8-bit and 16-bit grayscale, and provides control over image manipulation, compression, decompression, and conversion.
