Acoustic Spectrum of Liquids

As is now well known, examination by means of a Fabry-Perot etalon reveals remarkable changes in the spectral character of monochromatic radiation when it is scattered within a dust-free liquid. Earlier studies in this laboratory1 disclosed that the relative intensity of the undisplaced central line to that of the two Doppler-shifted companions appearing on either side of it varies greatly from liquid to liquid, being for example much larger in carbon tetrachloride than in toluene

Assessing the Diagnostic Precision of Cone Beam Computed Tomography (CBCT) in Temporomandibular Joint Arthritis: A Comprehensive Review

<p>Temporomandibular joint disorders (TMD) are prevalent among a substantial portion of individuals. One such challenging condition is temporomandibular joint arthritis (TMJ arthritis) which is characterized by inflammation and deterioration of the TMJ. There is a wide array of imaging techniques available for the evaluation of the temporomandibular joint (TMJ), encompassing computed tomography (CT), magnetic resonance imaging (MRI), cone beam CT (CBCT), conventional radiography, and ultrasonography. CBCT, as compared to CT, offers the advantage of producing high-resolution 3-dimensional multiplanar TMJ arthritis images while requiring a lower radiation dose. CBCT provides the capability to analyze complex structures, such as bones, accurately. It additionally reduces scattered radiation, thereby enhancing image quality. The purpose of this review article is to comprehensively analyze the existing literature and research results to evaluate the diagnostic effectiveness of CBCT in detecting TMJ arthritis. </p><p>Keywords:- Temporomandibular Joint (TMJ), Cone Beam Computed Tomography (CBCT), Temporomandibular Joint Disorder (TMD), Temporomandibular Joint Arthritis (TMJ Arthritis), Osteoarthritis (OA).</p&gt
