Article Synopsis
- - Tranexamic acid (TXA) is beneficial in reducing blood loss and the need for blood transfusions in patients undergoing elective abdominal and pelvic cancer surgeries.
- - A systematic review of 12 studies showed that those receiving TXA had significantly lower blood loss and were less likely to require red blood cell transfusions compared to those who didn't receive TXA.
- - The use of TXA did not increase the risk of venous thromboembolism, but more research is needed to understand its effectiveness across different types of cancer surgeries.
Comparison of freehand 3-D ultrasound calibration techniques using a stylus.
Ultrasound Med Biol
October 2008
In a freehand 3-D ultrasound system, a probe calibration is required to find the rigid body transformation from the corner of the B-scan to the electrical center of the position sensor. The most intuitive way to perform such a calibration is by locating fiducial points in the scan plane directly with a stylus. The main problem of this approach is the difficulty in aligning the tip of the stylus with the scan plane.

The principle of operation is that the beam is aligned with a set of coplanar wires strung across a rigid frame. The probe and frame are mounted on a precision-manufactured mechanical instrument which allows adjustment and measurement of their relative pose.
