About this file
This is a technical specifications document for the procurement of a multi-slice spiral computed tomography (CT) scanner for whole-body scanning. The document is structured as a declaration form where potential bidders confirm compliance with the listed technical requirements.
The equipment specifications include: a minimum 32-slice physical (64 reconstructed) CT scanner with a 70 cm gantry tunnel diameter and 0.35-second rotation time; a generator with minimum 55 kW power and X-ray tube capabilities of 460 mA maximum current and 140 kV maximum voltage; a solid-state detector with at least 54,000 elements across 32 physical rows providing 40 mm anatomical coverage per rotation; a motorized patient table supporting 225 kg with 1,730 mm scanning range; image reconstruction capabilities including 1024×1024 matrix with at least 28 frames/second iterative reconstruction and 15 pairs of lines per cm spatial resolution; and operator console with 19-inch color LCD monitor, DICOM support, image archiving, network transfer, ECG synchronization, and cardiac imaging capabilities. The system must include specialized software packages for multiplanar reconstruction, 3D volume rendering, cerebral perfusion analysis, vessel analysis, and coronary vessel imaging with Ukrainian-language instructions. Additional required equipment includes uninterruptible power supply, voltage stabilizer, power distribution board, lead glass shielding (800×1200 mm minimum), automatic bolus injector, and medical film printer. The supplier must provide equipment delivery, commissioning, specialist training for medical professionals, and 12-month warranty service from commissioning date. A certificate or declaration of compliance with Ukrainian technical regulations is required.
