Lips and mouth are the most recognizable parts of the lower face. The morphometry of the facial organs is important for the balance of the face. Besides congenital anomalies occur on the lips, some kinds of deformities might be seen because of trauma or carcinoma. In this respect, lips are in the study of plastic surgery, maxillofacial surgery and orthodontics. Lip morphology also takes an important role in forensic facial reconstruction (facial approximation).

Positron Emission Tomography and Computed Tomography in Planning Treatment for Patients Undergoing 3-Dimensional Conformal Radiation Therapy for Non-Small Cell Lung Cancer That Cannot Be Removed by Surgery
RATIONALE: Diagnostic procedures, such as positron emission tomography and computed tomography, may help learn the extent of disease and allow doctors to plan 3-dimensional conformal radia...

Researchers hope that this new non-invasive multi-detector scanner (DSCT) will provide diagnostic information comparable to the combination of traditional SPECT (for function and blood flo...
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
An imaging technique using a device which combines TOMOGRAPHY, EMISSION-COMPUTED, SINGLE-PHOTON and TOMOGRAPHY, X-RAY COMPUTED in the same session.
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
Three-dimensional computed tomographic imaging with the added dimension of time, to follow motion during imaging.
The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
Congenital conditions are those which are present from birth. They include structural deformities or loss of function in organs such as the <!--LGfEGNT2Lhm-->heart, gut or skeletal system. They can be corrected by <!--LGfEGNT2Lhm-->surgery, m...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
