Failed projection of Townes skull at 5.34. There has never been a reason to include the face, cervical spine and thyroid on a Townes projection. Just reduce the angle by 4 degrees and ensure the collimation is to the brow line. Hopefully you know that changing the tube angle this way only changes the collimation. The foot xray at 11.49 shows the lower leg being needlessly included in the primary beam which doubles the dose and the scatter damage to the radiograph. Ensure you understand the geometry of projections, then use collimation as your guide rather than centring points. 75% of qualified radiographers fail my geometry test kzbin.info/www/bejne/o4uzdZKdgdhoetksi=ucP13VwC0Sv-4JFO. Look at my channel for examples of collimation based positioning which will result in you becoming a master of the art rather than someone who completes a task to adequately specifications

Perpetuating the error than began in the 1920s. No one knows were T7 is until after the xray is taken. Obviously, if you do follow the technique, you deliver a needless primary beam dose to the thyroid and mandible. Just collimate accurately to the cassette or less, and then ensure the top of the lungs will appear on the top of the radiograph. It is likely the tutor on this video will fail my x-ray beam geometry test because anyone who is locked into centring points never has to apply geometry principles. kzbin.info/www/bejne/o4uzdZKdgdhoetksi=ucP13VwC0Sv-4JFO

A well trained radiographer would not include the skull and shoulder joints on a chest xray. Lack of collimation increases the radiation dose enormously. The problem is in trying to find T7 and using that as a centring point. No one knows where it is, and no one judges the success of a chest xray by finding T7 in the centre. Instead, collimate to the size of the cassette, then use the illuminated field as your only positioning guide.
@thevoiceharmonic5 күн бұрын
Stop using rules of thumb to find the centring point. Instead, collimate accurately, then use the illumination of the Light beam diaphragm as your positioning guide. For pelvis, you need the iliac crest on the top of the image. This minimisation of the primary beam is the best way to reduce radiation dose.

My 'no centring point' method would offset the tube to ensure accurate collimation to the detector, then back to central lock. Knowing the dimensions of the primary beam top to bottom means all I need is the iliac crests on the top of the image so I ensure that happens through palpation or with obese patients, from them indicating where their greater trochanter is. The accurate collimation will also allow exact placement of gonad protection
@thevoiceharmonic10 ай бұрын
I would use accurate collimation and put the axial and lateral on a 18x24cm cassette. When the digital age emerged I would do the axial in a standing position to speed up the procedure and improve image quality
@thevoiceharmonic10 ай бұрын
There is a rule. Any time radiation misses the cassette, you have used the wrong tube angle. Never use centring points. Always use collimation as your only guide.
@thevoiceharmonic10 ай бұрын
As a retired radiographer I have performed this difficult procedure hundreds of times. My recommendation is to set the tube and the cassette in position well before you attempt to raise the opposite let. If you use a 35x43cm focused grid, you will need to angle it to ensure there is no grid cut off. If this sounds illogical, you probably fall into the trap 75% of qualifieds do where there is a fundamental misunderstanding of the geometry of a projection. kzbin.info/www/bejne/o4uzdZKdgdhoetksi=e5HMqOBuOfOlomlu. You should be able to collimate well within the limits of the cassette and the skin edge. Not collimating well may triple the radiation dose and that may be significant for people who remain in the xray room as the scatter energy relates to the primary beam energy. I would also use an aluminium wedge filter

A woeful massive unnecessary radiation dose shown at 4.30 with what I consider to be over injection of contrast media. One good idea if you have the opportunity is to use the screening unit erect and at Focus Film Distance using the device as an erect bucky.

do a web search for "tube rating charts" and there are a bunch out there. Each tube has its own rating chart. The ones you find in the text book are generic, but useful from a learning perspective.

great tutorial. Respectfully, I would add to make sure a few minutes pass before taking your image. This will allow any small amounts of free air to float up and be seen.
@x-rayeducation2277 Жыл бұрын
thank you for your comment, and you are correct: it is good to wait a few minutes before taking the image. In reality, when I have done these at the hospital it normally takes multiple helpers and several minutes to get the patient positioned, so usually by then the requisite time has passed. Decubitus views on a large semi-conscious patient can be very difficult to obtain.

Can you explain when should turn on filament and apply KV on x ray tube. Assume filament is preheating current is always present.
@x-rayeducation2277 Жыл бұрын
If you have a patient who can't cooperate or for some reason (like they're on a vent) is not able to breath hold, then you should "rotor up" and get the filament hot and the rotor spinning, then when it looks like the patient has a breath you make your exposure (apply kV). But normally, you don't need to do this. most systems you can just press the "expose" switch and the system rotors, heats the filament, then makes the exposure as soon as the correct RPM and mA have been reached. Typically just 1-2 seconds start to finish.

With the oblique, I set the shape of the collimation I want and the angle the sternum will be then the patient stands PA or lies down. I use the central line on the Bucky and the sternal notch to determine where the top of the sternum will be on the tightly collimated radiograph. Always a breathing technique. For the lateral, I will also set my collimation first and my only positioning reference point is the sternal notch. I rotate the collimator to run it parallel to the sternum 2 inches wide. Lean the patient forward or backwards. On more solid builds with muscle and fat, ensure you give enough exposure. Curious about the lateral shown in the video. If it was a true lateral, the humeral head would not be in the image. The fact the other one is not in the image means it wasn't a true lateral. So my technique would reduce the radiation dose to 1/6th in both images.
@thevoiceharmonic Жыл бұрын
No last moment collimation to well within the skin edge? That will improve the quality of the image a lot. I use a wedge filter often to even out the exposure. A big grid can be used but not vertically, the angle required to satisfy the focus and geometry. Grid work is often done badly because a mistake has been passed down through the generations to do with angulation and geometry. If you learn it, you can master radiography. If you don't you will be trapped in monotony without the opportunity to produce perfection. kzbin.info/www/bejne/o4uzdZKdgdhoetk
