What is the canthomeatal line?

What is the canthomeatal line?

The canthomeatal line is also referred to as the orbitomeatal line and is defined as running from the lowermost point of the eye’s bony orbit to the preauricular point.

What is Orbito meatal baseline?

The orbitomeatal line, also known as the canthomeatal line, was the traditional axial plane used for CT of the brain. It was easily identified on the inspection of the patient’s head when tilting the gantry or patient’s head to achieve a standard axial plane.

What is radiological baseline?

Abstract. For many years the radiographic and Reid’s base lines have been used as the main anatomical landmarks for positioning various projections of the skull, sinuses, and facial bones. Both base lines maintain a constant relationship to the cranial vault which does not vary from infancy to adulthood.

What is positioning in radiography?

Radiographic positioning refers to the way the body is placed, meaning general body position, or the part of the body that’s the closest to the image receptor, meaning the specific body position.

What is skull AP?

The skull anteroposterior (AP) view is a non-angled radiograph of the skull. This view provides an overview of the entire skull rather than attempting to highlight any one region.

What is the average angular difference between the Orbitomeatal and the Infraorbitomeatal lines in an adult skull?

What is the average angular difference that exists in adults between the orbitomeatal and infraorbitomeatal lines? What is the average angular difference between the orbitomeatal and glabellomeatal lines. An 8-degree angular difference exists on average between the orbitomeatal and glabellomeatal lines.

What does low baseline mean?

Baseline SBP was defined as mean outpatient SBP within 2 years before injury. Trauma SBP was defined as first SBP reading after presentation for trauma. Baseline and Trauma SBP were classified as Low (<110 mm Hg), Normal (110-139 mm Hg), or High (≥140 mm Hg).

What is FH plane in anthropology?

The Frankfort Horizontal (FH) was originally introduced at an anthropological conference in Frankfurt, Germany in 1884. It was defined as a plane extending from the left Orbitale to both Porion points. The plane was initially used as a craniometric reference plane for classification purposes.
