The time of magnetic resonance imaging has always been a major obstacle to its application. Conventional acquisition methods are slow in imaging, and for technologies that require time resolution such as dynamic enhanced scanning, motor organ imaging, perfusion imaging, functional imaging, and economic benefits, conventional acquisition methods cannot meet these needs. Apsaras Spark is equipped with RAPID extreme speed imaging (parallel acquisition) technology to meet these needs, While maintaining resolution, it can improve scanning speed by several times, and at the same time, it is more user-friendly to adjust the acceleration factor after the decimal point, making the image quality and scanning speed perfectly match.

High definition magnetic sensitivity imaging and vascular imaging：

Advanced MRA Package

Used for angiography imaging (MRA). CTA and DSA can bring ionizing radiation to patients. To avoid ionizing radiation, the use of MR for angiography imaging in clinical practice is increasing. In order to meet clinical needs, Kangda Intercontinental has independently developed various advanced vascular imaging functions, forming an advanced MRA software package. The advanced MRA software package of Apsaras SE includes the following functions, which can obtain images of high flow velocity blood vessels, low flow velocity blood vessels, small blood vessels, and also has multiple functions for displaying blood vessels throughout the body in a large and clear manner.

TRAQ (Time Resolved CE-MRA Acquisition)

Used for continuous high-speed scanning of MRA to obtain images of contrast agent flow. This function first pre scans the mask, and then performs continuous high-speed scanning while performing mask and real-time image subtraction during contrast agent injection to obtain images similar to DSA.

TPEAKS (PEAK Artery Enhancing K-space Filling Sequence)

Used to obtain high-quality CE-MRA images. The TPEAKS function is to divide the raw data of CE-MRA into three collection periods, fill the data with the highest arterial signal intensity in the center of K-space, thereby reducing the scanning time dependence of vascular display and obtaining good MRA images.

VASC-ASL （Arterial spin labeling method MRA）

VASC-ASL refers to a new non contrast MRA technology that combines ASL (Artistic Spin Labeling) with non contrast MRA. This technology uses a 180 ° inverted IR pulse signal on SpinLabeling. According to the position of the pulse excitation block (slab), selecting the area for spatial labeling, combined with the setting of TI (null point), can suppress background signals and specific blood signals with T1 values. Due to the ability to control such a choice, it has become possible to separate the arteries and veins of the entire body from the trunk to the fingertips of hands and feet, as well as to achieve functional non contrast MRA images, which have been difficult in previous imaging examinations.

Advanced 3D High Speed Volume Imaging (TIGRE T1weighted Gradient Echo Nature for the Sequence)

Used to obtain dynamic enhanced scanning images. For clinical diagnosis of breast and liver parts, it is hoped to obtain multi temporal, high-resolution 3D liposuction images. The TIGRE function can correspond to thin layer and large field scanning, while using high-speed gradient echo sequence and advanced grease pressing technology H-sinc independently developed by Kangda Intercontinental to obtain high-quality 3D volumetric images of large field and uniform grease pressing as shown in the following figure. The use of TIGRE is beneficial for detecting small lesions and making qualitative judgments of the lesions.
