In this video, we focus on how the success or failure of clinical radiation treatment is determined by some radiobiological determinants as the capability of cells to repair of DNA damage, redistribution of cells in the cell cycle, repopulation, and reoxygenation of hypoxic tumor areas
In this video, the principle of fractionated radiotherapy is explained, which is concerned with dividing the total dose required to control and eliminate cancer over several separate sessions. New methods in fractionation were compared according to their ability to control the tumor and cause subsequent toxicity in normal cells
In this video, radiotherapy types were identified in terms of the purpose of its use, the time of its use, or according to the location of the source. This is in addition to mentioning the different types of radiotherapy devices and the advantages of each of them, especially the devices that have the ability to provide a radiation beam dedicated to the condition of each patient in terms of the shape of the beam and the intensity of its energy.
In this video, the stages of radiation therapy are explained, starting with receiving the patient and diagnosing his condition, and then designing a treatment plan that suits his case based on the information collected about the location and type of tumor during the simulation session to ensure the greatest possible effectiveness on the target with the least damage to the surrounding organs
In this video, the focus is on explaining the reasons that lead to a difference in the response to radiation between different tissues. This is in addition to identifying statistical methods to study the probability of complications occurring in healthy cells after exposure to radiation doses during attempts to control the activity of cancer cells.
In this video, basic information about the cell and its mitotic activity was retrieved, with a focus on the causes that led to an error in the rate of this division and the formation of rapidly proliferating cancer cells.
"In this video, the time scales of major events that lead to the biological effects of ionizing radiation were introduced. With reference to the factors that cause modification of the intensity and the possibility of these effects occurring, as the characteristics of the used radiation or the target tissue characteristics
In this video, the effects of radiation on cells and their mitotic activity were identified, with reference to two terms(the plating efficiency, Surviving Fraction), that help study the behavior of cancer cells after exposure to radiation
In this video, the hypotheses that were used to draw the relationship between survival fraction and the doses used in treatment were identified in light of various variables such as LET of the used radiation. dose rate, temperature. oxygen level , etc.
In this video, it was learned how cancer starts in the breast, what are the factors that raise the risk of breast cancer, and what early signs can be monitored to speed up the detection of the disease. A distinction was also made between cases that constitute a risk and are liable to transform into cancer, and between those cases that represent benign tumors or other less dangerous conditions.
In this video, it was learned how different tumors appear in mammograms, and what are the morphological signs that distinguish between the appearance of malignant tumors and benign tumors. In addition to getting acquainted with the global mammogram image classification system (BIRADS) to facilitate patient follow-up
In this video, a group of other uses of the mammogram device were reviewed, which help in the diagnosis and treatment of breast tumors, such as imaging the blood vessels in the breast, or imaging the milk ducts to detect any hidden signs of disease. Also the use of the device to accurately locate the masses before surgery. This is in addition to an application to use artificial intelligence to help detect various pathological signs in mammogram images
In this video, other tools for detecting tumors in the breast were identified, including biopsy, which is considered the most accurate among the different diagnostic methods, with an explanation of the role of various imaging tools in this process. Nuclear imaging tools have also been identified to detect various tumors and their places of spread, regardless of their size or the condition of the patient.
In this video, Ultrasound imaging which is one of the most important methods of detecting breast diseases was explained. When was it used? and Is it considered an alternative to mammogram imaging? The process and tumor appearance are also mentioned
In this video, a group of tools used in breast imaging was introduced as 3D mammogram, cone beam CT, and MRI. They are compared in terms of accuracy and sensitivity in detecting breast tumors.
In this video, the different types of radiation generators used in radiotherapy were reviewed, as they were divided into two main groups according to the radiation energy generated, kilovoltage units which are usually used in the treatment of superficial tumors, and megavoltage units which are suitable for deeper tumors.
In this video, reference was made to a new type of radiation generator that may be suitable in the future for clinical use in radiation therapy, which is heavy element beam generators. The change in radiation dose distribution along the depth was also discussed
This video focused on explaining the term (isodose curve), which represents a diagram used to study points that have the same absorbed dose inside the body regardless of their location or depth, which helps later in understanding the severity of the effects on the tissues surrounding the tumor during treatment sessions.
In this video, the mechanisms that are used to change the shape and the intensity of the therapeutic beam was introduced. Also, reference was made to the (Half-value layer) term that helps in choosing the type and the thickness of the materials that are used as radiation blockers during radiotherapy sessions.
