A novel tomographic method based on the laser speckle contrast, speckle contrast optical tomography (SCOT) is introduced that allows us to reconstruct three dimensional distribution of blood flow in deep tissues. This method is analogous to the diffuse optical tomography (DOT) but for deep tissue blood flow. We develop a reconstruction algorithm based on first Born approximation to generate thr...

Computed tomography can be used to create highquality three-dimensional images. An example of a con uent left pulmonary vein in a patient with idiopathic paroxysmal atrial Ž brillation is shown in the Ž gure. The common trunk (arrows) and individual branches (arrowheads) are clearly seen. Thus, three-dimensional computed tomography of the heart may be useful for visualizing the pulmonary veins...

We theoretically investigate electron energy loss spectroscopy (EELS) of metallic nanoparticles in the optical frequency domain. Using a quasistatic approximation scheme together with a plasmon eigenmode expansion, we show that EELS can be rephrased in terms of a tomography problem. For selected single and coupled nanoparticles we extract the three-dimensional plasmon fields from a collection o...

F rom painters to cartographers to medical imagers, humans have faced the challenge of depicting the 3-dimensional (3D) world using 2-dimensional (2D) displays. The transition from planar to tomographic imaging engendered various approaches to display the physiologic information contained in 3D single-photon emission computed tomography (SPECT) and positron emission tomography (PET) cardiac stu...

Cone-beam computed tomography (CBCT) is the most common three-dimensional (3D) imaging technique used in dentistry [...]

3D HFU: 3-dimensional high-frequency ultrasound scan CSAMI: Cutaneous Sarcoidosis Activity and Morphology Instrument PET/CT: positron emission tomography/ computed tomography C utaneous involvement occurs in 25% to 30% of patients with sarcoidosis. Effective treatment of the disease has historically been challenging given a lack of an objective, reproducible marker of disease activity. Here we ...

Image fusion software can derive a fusion image from single photon emission computed tomography and computed tomography scans. We applied a three-dimensional fusion image to detect sentinel lymph nodes (SLNs) in 3 patients with malignant melanomas of the lumbar, vulvar and head region, respectively. During each operation, we detected SLNs at the expected site, as indicated by the fusion images....

This paper discusses sampling system design for estimation of multidimensional objects from lower dimensional measurements. We consider examples in geometric, diffractive, coherence, spectral and temporal tomography. Compressive tomography reduces or eliminates conventional tradeoffs between temporal and spatial resolution.

We describe a case of an incidentally-diagnosed ectopic tooth showing anomalous morphology in the maxillary antrum, using three-dimensional reconstruction of computed tomography images of the tooth obtained by multi-detector computed tomography.
