Orbital x-ray. Waters view showing diffuse prominent mucosal thickening in the right maxillary sinus and mild nmucosal thickening in the left maxillary sinus. Orbital x-ray or orbital radiography is an x-ray of both left and right eye sockets, to include the Frontal Sinuses and Maxillary Sinuses.
Sinar-X. Sebuah foto sinar-X (radiograf) diambil oleh Röntgen. Sinar-X, juga dikenal sebagai radiasi-X, adalah suatu bentuk radiasi elektromagnetik berenergi tinggi. Dinamakan sesuai dengan nama ilmuwan Jerman, Wilhelm Conrad Röntgen yang menemukannya pada 1895, sinar ini dinamakan "X" untuk menunjukkan sifatnya yang tidak diketahui pada saat ...
Nov 18, 2023 · Orbits X-ray imaging, also known as orbital X-ray, is a specialized radiographic technique designed to capture detailed images of the orbits – the bony cavities that house the eyes. This imaging modality provides healthcare professionals with a clear visualization of the eye sockets, aiding in the diagnosis and treatment of various ocular and ...
Orbital atom adalah sebuah fungsi matematika yang menggambarkan perilaku sebuah elektron ataupun sepasang elektron bak-gelombang dalam sebuah atom. Fungsi ini dapat digunakan untuk menghitung probabilitas penemuan elektron dalam sebuah atom pada daerah spesifik mana pun di sekeliling inti atom.

Ocular or optic refers specifically to the globe (eyeball). Orbital refers to all the contents of the bony orbit, encompassing both the intra and extraocular structures.
Orbits are roughly pyramidal in shape, broad based anteriorly and tapering to an apex, posteriorly. The normal volume in an adult is approximately 30 mL, of which the globeoccupies 6.5 mL. The orbit has a roof, floor, medial and lateral wall. The orbit is open anteriorly where it is bound by the orbital septum, which forms part of the eyelids. Post...
The fascial sheath of the eye (Tenon's fascia), orbital fat, obliques and bony attachment of the recti provide stability to the eyeball within the orbit and prevent it from sinking or retracting. See article titled 'stability of the eye'.
The fascial sheath of the eye (Tenon's fascia) prevents the eye from sinking. The fascia is applied like a bursa to the back of the eye, from the corneoscleral junction to the attachment of the optic nerve and is thickened over the extraocular muscles. Over the lateral rectus, the tubular prolongation is thickened to form the lateral check ligament...
The eyes always rotate about a fixed centre, which is its own geometrical centre. The contracting recti musclesdo not displace the eye posteriorly due to: 1. bony attachment of the recti muscles 2. presence of orbital fat 3. forward pull of the superior and inferior oblique muscles
Presentation. Left eye hematoma, poked by sharp end of a leaf. No active bleeding. Patient Data. Age: 65 years. Gender: Male. x-ray. No gross radiodense foreign body is detected. Case Discussion. This case is an example of a normal orbits series comprising of the Waters (OM0°) and lateral views.
X-ray notation. X-ray notation is a method of labeling atomic orbitals that grew out of X-ray science. Also known as IUPAC notation, it was adopted by the International Union of Pure and Applied Chemistry in 1991 as a simplification of the older Siegbahn notation. [1]
