Single shot three-dimensional imaging of dilute atomic clouds [PDF]

, 2014
Light field microscopy methods together with three dimensional (3D) deconvolution can be used to obtain single shot 3D images of atomic clouds. We demonstrate the method using a test setup which extracts three dimensional images from a fluorescent $^{87}$

The diagnostic accuracy of 3D ultrasound compared to 2D ultrasound and MRI in the assessment of deep myometrial invasion in endometrial cancer patients: A systematic review

Taiwanese Journal of Obstetrics & Gynecology, 2022
Endometrial cancer is a common malignancy in women worldwide, with myometrial invasion (MI) being an important prognostic factor, usually assessed via imaging techniques.

Three Dimensional Electrical Impedance Tomography [PDF]

, 1996
The electrical resistivity of mammalian tissues varies widely and is correlated with physiological function. Electrical impedance tomography (EIT) can be used to probe such variations in vivo, and offers a non-invasive means of imaging the internal ...

Three‐dimensional decoupling imaging method for wideband two‐dimensional multiple‐input‐multiple‐output radar

IET Radar, Sonar & Navigation, 2022
Wideband two‐dimensional multiple input multiple output (MIMO) radar can be used for target three‐dimensional (3‐D) imaging. As the echo of wideband MIMO radar is derived from both time and spatial sampling, the time‐frequency coupling is contained ...

Application of Three-Dimensional Technology for the Preoperative Evaluation of Retroperitoneal Tumors

IEEE Access, 2019
With the development of computer medical imaging technology, three-dimensional technology has been gradually applied in medicine. We try to investigate the application value of 3D technology in the preoperative evaluation of retroperitoneal tumors.

Three dimensional imaging of short pulses

, 2003
We exploit a slightly noncollinear second-harmonic cross-correlation scheme to map the 3D space-time intensity distribution of an unknown complex-shaped ultrashort optical pulse.
