Basic concepts Flashcards
What is gross anatomy?
It is a familiar way to talk about anatomy with a emphasis on studying body systems. Focus on shape, function and location
What is sectional anatomy?
Study of regions of the body, with a focus on anatomical relationships of structures within a given region.
How is sectional anatomy viewed?
Viewed in slices or sections
To get visualization of an entire organ what must we do imaging wise? and why?
We must take multiple sequential images in slices, because structural relationships vary depending on the plane of view
What is 3D interpretation?
When a sonographer scans 2D images in more than one plane
What is anatomical position?
Standard method to describe patient position. In this position patient is
1. erect facing towards the observer
2. arms are at the sides
3. Palms face forward
4. Thumbs face away from body
How do we use anatomical position?
used to describe location of structures in or on the body, this ensures consistency of description and reduces confusion
What are the three Major anatomical planes we will look at in ultrasound
- Sagittal
- Transverse
- Coronal
What is longitudinal plane?
Plane parallel to the long axis of a structure but not necessarily a sagittal plane on the body
What is oblique plane?
Plane at an angle between the sagittal and/or transverse plane and/or coronal planes
What is acoustic window?
Refers to the location from which an ultrasound transducer makes its scan
How does a sonographer control the acoustic window?
Since the transducer is mobile the window is controlled by the sonographer. Basically it corresponds with the position of the transducer on the patients body
What images are “taken” in the acoustic window?
only anatomical structures directly beneath the beam of the transducer can be investigated
What is ipsilateral?
When structures are on the same side
What is contralateral?
When structures are on the opposite side
