The tube was constructed as a vacuum tube which used a filament that heated up producing the electrons. The filament added more power to the X-ray tube allowing the tube to heat up more, and producing more intensity with each strike from the cathode to the anode. The advantage of the Coolidge Tube was it was more stable allowing you to increase or decrease the current and its intensity. Tungsten was also introduced to the tube allowing for more intensity of the X-ray while being struck due to its high atomic number. ]]> 2020-09-20 02:43:47 UTC https://padlet.com/00028272/z7bgt966bb8gjq21/wish/761479795 00028272 https://padlet.com/00028272/z7bgt966bb8gjq21/wish/761986008 Bertha Roentgen's Hand

According to The Definitive Blog, by 2026, there will be an increase in artificial intelligence from $21 billion to $264.85 billion! AI is used to analyze data and create algorithms that can predict issues and find current issues already in the body. It is beneficial because it can spot issues that are undetected by humans.

The increased texture in the image allows the Radiologist to view more details which leads to better diagnoses. In the near future, there may be special eyewear available that has the ability to visualize in 3D and move a screen, or even holograms with just the movement of one’s hands. Technology is also being developed to be able to 3D print a copy of a patient’s body to assist with examining and diagnosing. This will be very beneficial to many fields, especially surgical, to help planning the surgery.

For example, PET scans have recently been used to detect amyloid plaques in the brains of Alzheimer’s patients. This technology can be used to detect this disease earlier than before and allow for more treatment options. ]]> 2020-10-01 00:01:15 UTC https://padlet.com/00028272/z7bgt966bb8gjq21/wish/793268321 lexibradley124 https://padlet.com/00028272/z7bgt966bb8gjq21/wish/793269180 These are devices used on patients outside of the clinical setting, for example, at home, to bring radiologic technology into the real world. These inexpensive, convenient, portable devices allow increased imaging to patients in other locations which may lead to increased diagnoses. Two common devices in as of now are a portable MRI technology glove and a portable brain scanner. ]]> 2020-10-01 00:01:51 UTC https://padlet.com/00028272/z7bgt966bb8gjq21/wish/793269180 00312044 https://padlet.com/00028272/z7bgt966bb8gjq21/wish/796418210 Timeline and description of different events
