They said they were able to confirm that the growth was a tumor by using computed tomography, or CT images.

他们表示可以利用电子计X线体层照相（CT影像）确定长大的是肿瘤。

The computed tomography machine works like a magnetic resonance imaging or MRI machine giving inspectors a 3D view that can be rotated 360 degrees.

计层扫描的工作方式类似于核磁共振成像，可提供检查人可以360度旋转的三维视图。

This method is called X-ray computed tomography or X-Ray tomography.

这种方法称为 X 射线计层扫描或 X 射线层扫描。

1971 Radiographers at a London hospital conduct the first computed tomography scan.

1971年，伦敦家医院的放射技师进行了第次计层扫描。

Radiology is concerned with imaging of the human body, e.g. by x-ray computed tomography, ultrasonography, and nuclear magnetic resonance tomography.

放射学涉及人体成像，例如通过X射线计层扫描，超声波检查和核磁共振层扫描。

Most commonly, transesophageal echocardiography is used to evaluate for left atrial appendage thrombus, although cardiac computed tomography and geography has been demonstrated to have excellent sensitivity and specificity as well.

通常情况下， 经食管超声心动图用于评估左心耳血栓，尽管心脏计层扫描和地理定位也显示出极佳的敏感性和特异性。

In the mid-1970s, hospitals began to introduce computed tomography, CT, which uses x-rays to provide 3D images by rotating the x-ray source and detector around the body as it passes through a tube.

20世纪70年代中期， 医院开始引入计层扫描技术（CT），该技术利用X射线， 通过在人体穿过管道时旋转X射线源和探测器， 生成三维图像。

This brings us to radiology which harnesses imaging techniques such as x-ray computed tomography or CT scans, MRI or magnetic resonance imaging, ultrasound and nuclear medicine to diagnose and treat a wide range of medical conditions.

这将我们带到了放射学领域，它利用成像技术如X射线计层扫描或计层扫描(CT扫描)、磁共振成像(MRI)、超声波和核医学来诊和治疗各种医疗状况。
