39th DaY oF aTTaChMent
I did what i have done for the past few days as trying my best to master the maintenance for almost all of the pumps. Surprisingly, i did 6 pumps before Mr Sin took me to the radiology department where the radiographer and radiologist will be there to do some scanning and diagnosis. The department consist of two levels. Level 2 is mostly for commerical purposes which means doing a general scanning like fracture. Level 1 consists of MRI, CT and x-ray for more serious cases. Some of the radiographers introduced the various devices such as MRI, CT and X-Ray in terms of operation and functions. The most amazing thing is the radiographer in charge of MRI asked me to enter the room where it is located. He brought a bunch of keys and asked me to feel the strength of the magnetic force. I actually placed the keys slowly to the MRI and felt the magnetic pull from the key. When you held the keys near to it, so near that you are able to see the keys floating.
Next location we went is the CT scan room. CT that we had only able to have a slice per revolution means more radiation exposure and slower to obtain the desirable number of slices. At first, CT will have a rough scan on the patient in order for the radiographer to select the region of interest that he likes to capture. It usually measure from the head to the pelvis and the distance will be in mm which is being calculated by the software.
Lastly, we went to the x-ray room. The radiographer told me that the only difference from the x-ray machine that they have it there compared to the level 2's is the cassette. In the cassette, there is a film that image is being captured on. For level 1, the film is reusable for quite a number of times which we can say it is more cost effective. If the image is not well-captured, you can erase it before developing it out. However, for level 2, the film only for once use so it is like the film in our camera once you capture, you can't remove it so it will consider a waste film if the image is not well-captured.
In Alexandra Hospital, there is this device that able to upload the film by putting it into the device and allow the radiographer to adjust the best type of brightness for the image in order to optimise the clarity of the image. The images will then be stored into the server allows radiologist and doctors to view it. However, it is yet to be done for the image to be viewed at the patient wards so far it is only accessible to that department for now.
