The main function and performance of NeuSight PET/CT 64

Tumor

•    Role in Oncology

•     Differentiate benign from malignant disease

•    Staging of disease

•    Treatment response

•    Radiotherapy treatment planning

Cardiovascular

•    Role in Cardiology

•    Myocardial perfusion and viability

•    Myocardial glucose metabolism

•    Myocardial receptor studies

•    Blood volume, wall thickness, wall motion

Nerve system

•    Role in Neurology

•    Epileptic foci localization

•    Assessment of Alzheimer’s disease and other forms of dementia

•    Assessment of Parkinson’s disease and other movement disorders

•    Research of neuroreceptor mapping

Health screening

•    The health screening of the high risk group with malignant tumor by PET/CT may facilitate the early discovery of malignant tumor.

•    The detection rate of malignant tumor of the normal group through routine health examination is 0. 3% ～0. 5%, while the detection rate of malignant tumor of the normal group through PET/CT is up to 2.2%. Meanwhile, most tumors were found at an earlier stage, so they have the opportunity for operation treatment.

Print and Report System

•    Compare, analyze, and track tumor progression with up to four sequential PET/CT studies

•    SUV-based semi -automatic tumor segmentation

•    Measurement of changes in tumor volume and metabolic activity

•    Coregistration of PET or CT data with a reference template (The Talairach atlas).

•    Quantitative analysis of brain images in both Talairach and patient space.

•    Comparison of functional data with sequential brain images on the same patient.

•    Analysis of 3D CT angiographic cardiac images/data providing a number of display, measurements and batch filming/archive features to study user-selected vessels.

•    Provide capability to visualize reformatted PET/CT perfusion and viability data.

•    Provide different ways of visualizing CT anatomy fused with PET functional information.

The cardiac acquisition system could assist the clinician in using automatic tracking software of CT contrast medium to reconstruct the data based on the time phase of cardiac cycle, which could find optimal diastole and systole and perform multi-phase time phase reconstruction. The system acquires data by means of prospective and retrospective scan modes.

The cardiac acquisition system helps the clinician to acquire PET multi-temporal data during cardiac cycle and edit ECG-gating parameter to conduct offline multi-temporal reconstruction. Moreover, you can choose the CT data at a particular phase as attenuation correction data to conduct offline PET image reconstruction.

Dynamic View software is available in console and/or advanced application workstation.

Point Diffusion Restoration

Use PSF (Point Spread Function) technology to improve image resolution and reduce image noise.

PET reconstructed transaxial Display Field of View (DFOV) of up to 70cm with CT based PET attenuation correction  and up to 70cm CT DFOV Wide FOV reconstruction

Mis-registered PET and CT attenuation correction data due to organ motion may be re-aligned and reconstructed again to try and recover proper PET attenuation correction to help avoid CT AC re-scans .

Add correction factor to iterative reconstruction and lower the noise caused by correction factor. Under the same image acquisition condition, this will improve image SNR compared with conventional reconstruction.

Target Iterative Reconstruction

The target iterative reconstruction aims at small object target in the image to restart iterative reconstruction and realize the reconstruction of high pixel image.

Reduce CT tube current, optimizing CT tube voltage to reduce dose of CT scan which is used for PET attenuation correction.

Partial Volume Correct

Correct partial volume of the image.

ClearView is an advanced iterative algorithm for double spaces, one is for original raw data space and another is for image space. With three levels of Slight, Standard and Ultra we can get perfect image quality with lower dose.

Weighted Least Square can effectively restrain noise image.

Dual screen avaliable, both scanning and diagnostic can be working at the same time, Largely improve work efficiency.

UPS (Uninterruptible power supply) guarantees that the PET gantry, the patient table and the console could work for a period of time after a power failure so that the customer can save the data. No work would be affected or no data would be lost because of the power failure.

In order to meet the power supply voltage standards of different countries, the input voltage would be converted into 380V/220V to ensure the normal operation of the PET/CT.
