Computed tomography is a highly advanced imaging procedure that can create accurate and detailed images using specialized x-ray techniques. CT is used to create images of a patient’s internal organs and body parts. The word “tomography” is derived from the Greek word tomos, which means to cut a segment or a section, and graphein, with means to record. And that is what a CT scan reveals: a segmented slice of the body and all its organs, muscles, and bones.
CT for Lung Cancer Screening
A recent study has revealed that a computed tomography of the lungs can be used to create a risk based screening process for lung cancer, and that this method might just be far superior to the modern guidelines for screening. According to the research, low dose computed tomography can be used effectively to reduce the chances of lung cancer deaths in patients that are known to consume tobacco. Although the advantages of using this screening method are numerous, it is not yet known whether this method can create major complications for individual patients that are exposed to this kind of radiation. The study had used a progressive and risk based measurement method. According to the current guidelines set by the USPSTF, more than 46 thousand death can be prevented in lung cancer patients aged 50 to 80, in the next 5 years. However, the researchers in the CT study stated that using their method, the number of lives saved could increase to more than 55 thousand in the next 5 years.
CT Used with 4D Printing for Futuristic Surgeries
In another groundbreaking case study, it was shown that computed tomography can be used in conjunction with 4D printing methods to create extremely accurate models of internals. These can be used by doctors during preoperative planning, especially in the case of hand surgery. According to the researchers, 4D printing, which is 3D printing with the added dimension of time, can be used to print haptic models. These models can be used by doctors to compile a superior data set on the patient’s anatomy and bones.
