Measurement of axial vertebral rotation using three-dimensional ultrasound images

BACKGROUND Axial vertebral rotation (AVR) is one of the important parameters to evaluate the severity and predict the progression of scoliosis. However, the AVR measurements on radiographs may underestimate its actual value. This pilot study investigated a new three-dimensional (3D) ultrasound method to measure AVR. METHODS Three cadaveric vertebrae T7, L1, and L3 were scanned with a 3D medic...

Measurement of vertebral rotation using a three-dimensional ultrasound image

Materials and methods Three cadaveric vertebrae T7, L1, and L3 were scanned with a 3D medical ultrasound system. The rotation angles of the cadaveric vertebra were recorded during the experiment. Nine sets of ultrasound data, from 0 to 40° with 5° increments, were recorded from each vertebra (27 sets in total). An in-house program was used to reconstruct the 3D vertebra images. The rotation of ...

Ultrasound measurement of vertebral rotation in idiopathic scoliosis.

Ultrasound can be used to outline the spinous processes and the laminae, and thus to measure axial rotation. Using our own technique, we measured vertebral rotation in 47 patients with idiopathic scoliosis. There was a strong linear relationship between the Cobb angle and the rotation of the apical vertebra in untreated patients, but this relationship was lost in patients who had had brace trea...

Three-dimensional Flexible Needle Streering Using Two-dimensional Ultrasound Images

One of the most commonly performed minimally invasive surgical procedures is needle insertion. Such needle insertions are often performed either for diagnosis (e.g., biopsies) or therapy (e.g., brachytherapy), both of which require accurate needle placement. These procedures are frequently performed under ultrasound image-guidance which provides visual feedback. Clinicians usually use rigid bev...
