Technical Solutions for Computed Tomography
1. Advanced Detector Technology
Detectors are the driving force of computed tomography (CT) technologies development. In a way, the detector itself determines the technical capability level of a CT system's proficiency. Minfound Medical has given special attention to the detectors research and development, that has resulted in the independent development of high-performance scintillation crystal and ASIC chip, the key detector components in a CT scanner, filling a significant technology gap in China. As a result of it's independent research, the company has established autonomous production of ASIC chip, electronic control circuit, anti-scatter grid (ASG) and detector materials, and has successively developed a family of CT systems for 16, 32, 64, 128, 256 and 512 slices.
2. Digital ASIC chip
Digital ASIC-chip is one of the key elements in computed tomography. Its characteristics such as noise, linearity, consumption, frequency range and sampling rate greatly impact the performance of the detector and the entire CT system. ScintiStar® detector use digital ASICs to directly produce a digital signal, resulting in lower signal consumption and higher efficiency.
3. AI Fast Workflow
Minfound Medical CTs are equipped with relevant artificial intelligence technology that covers processes from scanning routine to image reconstruction, can realize intelligent positioning, rapid scanning and reconstruction, increase workflow efficacy, ultimately helping doctors to improve time and quality of the diagnosis.
4. AI support implemented system stability
Using intelligent temperature control technology, the temperature change of the entire machine can be monitored in real time. When the temperature rises, AI automatically performs local intervention to ensure a stable working condition. With the help of AI, the temperature of each part of the detector is monitored and controlled in real time to ensure that the temperature of the various detector modules is constant, eliminating the artifact caused by temperature change. Such maintenance leads to an effective extension of the life of the detector.
5. Low dose scanning - safety and cost
Patented heavy earth ceramic material detector, compared to average rare earth ceramic material detectors, features doubled X-ray absorption rate, while the dose is halved. A series of dose reduction technologies ensure a shorter exposure time and lower X-ray dose though producing exceeding quality images, so the system can be optionally equipped with lower heat capacity X-ray tube for the low-budget solutions.
6. Software Infrastructure Properties
ImA technology automatically controls the output milliamperes of the tube according to the patient's size and the area being scanned, reducing the radiation dose.
NDI + as "intelligent double domain" iteration, is AI-based iterative reconstruction algorithm based on physical model. The principal lays in original data iterating simultaneously in projection domain and image domain.
Strip artifact suppression algorithm - reduces strip artifacts in shoulder joint and hip joint.
MAS inhibits artifacts caused by dentures and metal implants, reducing partial volume effect and significantly improving image quality.
Beam hardening artifact correction reduces artifacts between bone and soft tissue, also suitable for pelvic scan.
