Instructions and Help about cert108 partial exemption materials form

Okay so we're going to be looking at the Rasik protocols which are some of the most widely used protocols that you will encounter threats protocols coupled with abdomen and Tobit protocols are going to be typically what you're going to be doing on a routine daily basis also Shruti hit routine heads are going to be something that you do but they're asking protocols or something that you have to familiarize yourself with and so if we just look at what CT what kind of breakthrough CT has had I will see that we have improvement in longitudinal resolution conventional posickey with its ability to are contiguous sections with overlapping reconstructions that prove to be a benefit imaging through the body so basically what this what this is saying is that we have the ability to park a lot of images very rapidly and we don't have to have gaps in between the images we can have them continuous or going up against each other and so it's like a continuous scan the most important advance in imaging technique though has come through the improved temporal resolution attributed to the ability to acquire data during a single breath holder so that's something that you want to circle this single breath hold because a single breath hold results in decreased motion if you haven't actually taken the c-team physics class that might be a little strange to you that a single breath hold is going to decrease motion but just looking back at the old top scanners like the first and second generation of CTS there was a situation where a cable had to be unwound to allow the tube to go back and start in position zero again and begin rotating around the patient so the tube had to go back instead of circling around the patient at a continuous rate and because of this patient had to breathe at some point in time and so there would be in the middle of the scan of breath an expiration and allow the patient to breathe normals and then the patient would have to take a deep inspiration again and then you would begin the scan again and because of this many of images wouldn't line up and there would be a significant amount of overlap or not overlap and so single breath hold has really improved things also the single breath hold is due to shorter scan times which produce better images due to the amount of motion that accompanies the Rasik structures okay we know that the heart is always beating there's nothing you can really do besides cardiac gating for it and so there's always going to be motion in the thoracic cavity however we can't eliminate patient respiration and things like that which we have voluntary control over so that means that tourists can times help do this our variables that need to be considered for helical scan include collimation which is how tight your boundaries are for your image are you exposing the patient too much a pitch as we solve pitch a greater pitch means that you're covering more area then what is actually being scanned and so basically a greater pitch...
