CT LVAS scans, analyzes CT images providing rich data on regional lung function—enables radiologists to furnish new levels of quantified, data-based correlation between function and structure to patients' physicians—using existing CT scanning equipment.

CT LVAS扫描，分析CT图像提供丰富的区域肺功能数据，使放射科医师能够使用现有的CT扫描设备为患者的医生提供新的量化的，基于数据的功能和结构之间的相关性。

LOS ANGELES, Nov. 22, 2023 /PRNewswire/ -- 4DMedical, the leading producer of advanced lung function imaging software has received FDA clearance for its CT-based ventilation product (CT LVAS™). CT LVAS, designed for use with computed tomography scans, joins 4D Medical's XV LVAS® imaging software cleared for use with fluoroscopy In the United States.

2023年11月22日，洛杉矶/PRNewswire/-4DMedical是先进肺功能成像软件的领先生产商，已获得FDA批准其基于CT的通气产品（CT LVAS）™).设计用于计算机断层扫描的CT LVAS加入了4D Medical的XVLVAS®成像软件，该软件在美国被批准用于透视检查。

The FDA clearance for CT LVAS dovetails with the upcoming 4DMedical product, CT:VQ™. CT:VQ will enable quantitative perfusion (blood flow) data and visualizations to be extracted from CT scans..

FDA对CT LVAS的批准与即将推出的4DMedical产品CT:VQ相吻合™. CT:VQ将能够从CT扫描中提取定量灌注（血流）数据和可视化。。

Standard CT images provide clinicians with structural detail about patients' lungs—from which they try to infer information about disease and function. CT LVAS adds a wealth of data on lung performance on top of the structural detail of CT scans. This capability fills an information gap that enables radiologists to provide the objective, data-driven information that could materially inform diagnosis and treatment options..

标准CT图像为临床医生提供有关患者肺部的结构细节，他们试图从中推断有关疾病和功能的信息。CT LVAS在CT扫描的结构细节之上增加了大量关于肺部表现的数据。此功能填补了信息空白，使放射科医师能够提供客观的数据驱动信息，从而为诊断和治疗方案提供实质性信息。。

Greg Mogel, MD, consultant radiologist at 4DMedical notes, 'Having assisted with image interpretation of CT LVAS exams in Australia, I've seen the diagnostic power of adding functional assessment to the structural information provided in standard non-contrast chest CTs. CT LVAS allows radiologists to provide a whole new dimension of lung health information to referring clinicians needing answers.

4D医学笔记顾问放射科医师Greg Mogel在澳大利亚协助CT LVAS检查的图像解读后，我已经看到在标准非造影胸部CT中提供的结构信息中增加功能评估的诊断能力。CT LVAS允许放射科医师为需要答案的临床医生提供全新的肺部健康信息维度。

I look forward to sharing this release at the upcoming RSNA.'.

我期待在即将到来的RSNA上分享这个版本。”。

CT LVAS software processes existing CT scans using sophisticated algorithms derived from aerospace technology. These highly detailed reports include color-coded images of regional airflow and lung ventilation—overlayed on the patient's CT scan. CT LVAS uses a software-as-a-service model and requires no new capital equipment.

CT LVAS软件使用源自航空航天技术的复杂算法处理现有的CT扫描。这些高度详细的报告包括覆盖在患者CT扫描上的区域气流和肺通气的彩色编码图像。CT LVAS使用软件即服务模式，不需要新的资本设备。

Scans from existing CT equipment are uploaded for processing, where they are analyzed and returned to the radiologist as the Ventilation Report..

来自现有CT设备的扫描被上传用于处理，在那里它们被分析并作为通气报告返回给放射科医师。。

CT LVAS measures lung ventilation in tens of thousands of locations in the lungs. The Regional Ventilation Visualizations provide region-specific ventilation at deep inspiratory breath-hold for a mid-coronal slice and three axial slices—Upper, Middle, and Lower. The regional ventilation data is quantified in lung volume change and regional lung ventilation heterogeneity..

CT LVAS测量肺部数万个部位的肺通气量。区域通气可视化在深吸气屏气时为中冠状切片和上，中，下三个轴向切片提供区域特异性通气。区域通气数据量化为肺容量变化和区域肺通气异质性。。

'I am excited by the impact CT LVAS will provide caregivers and patients in the U.S.' says 4DMedical Founder and CEO Andreas Fouras. 'As we head to RSNA, I am thrilled that reimbursement has been approved for our XV LVAS product designed for fluoroscopy, and to also share FDA clearance for CT LVAS in the U.S.

4DMedical创始人兼首席执行官Andreas Fouras说：“我对impact LVAS将为美国的护理人员和患者提供服务感到兴奋。”当我们面对RSNA时，我很高兴我们为透视设计的XV LVAS产品获得了报销，并且还分享了美国FDA对CT LVAS的许可。

We also look towards the commercial release of CT:VQ and the opportunity to combine and provide the two sets of highly quantified lung pulmonary information from CT LVAS and CT:VQ..

我们还期待CT:VQ的商业发布以及结合并提供来自CT LVAS和CT:VQ的两组高度量化的肺-肺信息的机会。。

In healthy lungs, ventilation and perfusion are well-matched, meaning that airflow and blood flow are equally distributed throughout the lungs. 4DMedical's CT:VQ technology will enable regional changes in ventilation and perfusion to be quantified and visualized, allowing a detailed assessment of V/Q mismatch.

在健康的肺部，通气和灌注匹配良好，这意味着气流和血流均匀分布在整个肺部。4DMedical的CT:VQ技术将使通气和灌注的区域变化能够量化和可视化，从而可以详细评估V/Q不匹配。

Clinically, these scans will primarily be used for diagnosing pulmonary embolism, but they can also be employed to assess conditions such as chronic obstructive pulmonary disease, pulmonary hypertension, and to evaluate pulmonary vascular disorders..

临床上，这些扫描将主要用于诊断肺栓塞，但它们也可用于评估慢性阻塞性肺病，肺动脉高压等疾病，并评估肺血管疾病。。

Importantly, perfusion (blood flow) data and visualizations from CT:VQ can be combined with the ventilation data and visualizations provided by CT LVAS--for a highly quantified picture of lung performance.

重要的是，来自CT:VQ的灌注（血流）数据和可视化可以与CT LVAS提供的通气数据和可视化相结合-用于高度量化的肺部表现图片。
