[Technical application of three-dimensional visualization and measurement for breast cancer using multidetector-row CT scanner].

This paper describes an integrated methodology that addresses the operation of 3D imaging and measurement for the diagnosis and surgical operation of breast cancer. The main system for breast CT imaging used a multi-slice CT scanner and 3D-workstation. The clinical sequence was performed in three phases with non-contrast and biphasic contrast-enhanced studies that were performed with multi-slice helical CT scanning.

[Evaluation of the retrospective ECG-gated helical scan using half-second multi-slice CT: motion phantom study for volumetry].

ECG synchronized technique on multi-slice CT provide the thinner (less 2 mm slice thickness) and faster (0.5sec/rotation) scan than that of the single detector CT and can acquire the coverage of the entire heart volume within one breath-hold. However, temporal resolution of multi-slice CT is insufficient on practical range of heart rate.

[Visualization by dynamic CT: invention of 2D-CT chronogram].

Dynamic computed tomography is one of the methods used for the functional analysis of blood flow information. We devised a simple method of visualization for dynamic CT. Re-sliced images were stacked as multi-slice images for the different acquisition times to show a continuous spatial arrangement with dynamic data.
