MRIdian Machines Create Precise Radiotherapy Methods

More than half of cancer patients that receive a diagnosis are most likely to be treated with a form of radiotherapy. Radiotherapy is a treatment that provides a high dose of radiation using a piece of equipment such as a linear accelerator and is aimed at a given area to eliminate cancer cells. Today’s technology has been very successful with these methods of cancer treatment. Still, even with precise planning, radiotherapy has many obstacles to overcome. Simple internal movements within the body such as breathing, bladder filling, digestion, or tensing up can impact the tumor movement up to half an inch, which may cause radiation to damage surrounding healthy cells and tissues. Engineers have developed a type of magnetic resonance linear accelerator (MR Linac) to combat these movement issues with live, detailed images of the tumor with higher accuracy. Read More on how this equipment can be utilized for precise treatments on patients.

Scientist Search for the Next Elements to Add to Periodic Table

Nuclear physicist, Kosuke Morita at Japan’s Kyushu University is on the verge of creating the next new element for the periodic table. Morita and his team have successfully synthesized a new element to the periodic table, making it number 113. There is now a total of 118 known elements, and the race for number 119 is on. In nature, there are only 92 protons in a nucleus of an atom, but through research and experimentation, it has been possible to synthesize atoms with more in a lab. Element 119 is still a hypothetical element that would be the seventh alkali metal named ununennium. Morita’s team plans to conduct experiments using two types of particle accelerators, including the cyclotron beam and a linear accelerator. To read more information on how his team was successful in creation on element 113 and future plans for element 119, read here.  

Particle Accelerator in New York To Probe Protons and Neutrons

For the first time in decades, the United States will have its first new particle collider. The Department of Energy announced earlier this year that the new location of this machine will be at Brookhaven National Laboratory in Upton, New York. The research will be done with the instrument to study the dynamic makeup of protons and neutrons. The new particle collider is a strong electron microscope that shoots electrons at protons and neutrons in order to measure them. The use of these accelerators shows great promise for the future in the fields of nuclear medicine as well as quantum information technologies. The design process will, however, not be finalized until 2024, and then it will take about another six years for construction and start up to occur.

New Micro Particle Accelerator Chip

Scientists at Stanford Linear Accelerator Center (SLAC) have introduced a new technological milestone for a prototype nanoscale particle accelerator. The new gadget gives promise for cancer treatments and will provide more scientific access to the functions of traditional particle accelerators, which are two-mile-long devices. A team of researchers believes that the technology offered by these large machines can be scaled down in size for accessible use in labs. However, the micro single chip is much less powerful than the larger Linac machines they mimic. In theory, they can still accelerate electrons up to 94% of the speed of light in order to create a particle flow strong enough for medical use and research. The miniature creation is still years away from use in radiotherapy. The seemingly simple concept of scaling down the design of large Linac systems is easier said than done, but it shows promise for the future and gives evidence of what potential these microchips have.

Should I Replace or Upgrade My LINAC System?


Having a shiny LINAC system in your clinic entitles you to benefits and services other clinics lacking this technology do not. Such a system is imperative when dealing with minute cancer situations and can not only give the medical staff an edge but also give patients a guarantee of quality others cannot. That said, a proper LINAC system is, quite obviously, not a cheap system to not only implement initially but maintain over time. At one point a clinician or technician may decide the time has come to upgrade to what’s best out there, but such a decision is not so black and white. This article should briefly outline why so.

What Do You Have?

When making the decision to upgrade, you have to look at what you have already implemented. What you have may actually be satisfactory despite being old. LINAC systems themselves are as pricy as one may expect but are also modifiable with different parts that make up the whole. Linear accelerators can be classified as defined by their part status. Essentially, your linear accelerator can be classified from older and lacking upgrades, through newer but lacking and older and possessing upgrades, to newer and possessing upgrades. Where your system lies on the spectrum indicates whether or not making upgrades is worth the cost when considering the competency.

What is Your Budget?

Depending on the overall budget and success of your clinic you may find it smarter to simply upgrade certain parts on your older LINAC system. If money is no object you can naturally swap out your system – even if it’s new – for a newer, more modern and up-to-date model. Having an infinite source of funds is most likely not the case for most clinics, so you must take budget into effect and decide if your system is old enough to really warrant a true upgrade. Remember, upgrading certain parts of your system will always be cheaper than an outright replacement, and going with used upgrades is still a viable and more cost-effective option.

Do You Have Time?

When replacing a LINAC system completely, time is of great importance. Upgrading certain parts on a system can take hours and can be done overnight, but swapping out an entire system can take much, much longer. Are you able to survive with such an important machine out of the office for so long? If your system isn’t too old and has competent upgrades, then it can be hard to justify that absence. Any experienced clinician understands his or her own office enough to know whether or not that absence is detrimental to overall clinic success.

Measuring ERE with Gel Dosimeter

Radiotherapy treatment has continued to make huge progress especially after the introduction of MRI guidance systems. Although there are many advantages to this, there are unfortunately still obstacles that researchers are trying to understand more clearly such as the fact that in a high-field MR-linac, a strong magnetic field causes hot and cold dose spots which are better known as electron return effect (ERE). This specific phenomenon causes secondary electrons that enter a region of low density to be redirected back toward a high-density region that in turn creates larger dose into denser tissue. A scientific team has been experimenting with two Fricke gels to address this ERE issue. To learn more about this research, the article explains their process in the experiment and what research findings are showing to improve this issue in further radiotherapy treatments. 

Treating Cancer with External Beam Radiation

Cancer treatment has continued to evolve with new technology and knowledge on new innovative techniques to increase the effectiveness with fewer treatments needed. External beam radiation therapy is a form of treatment that aims radiation from a machine called a linear accelerator. The beam of radiation is aimed at a targeted area where tumor cells are found. This type of radiation therapy is a local treatment and treats the specific area in a person’s body such as lungs and not their entire body. There are several options when using external beam radiation therapy with all the same goal to deliver the highest dose of prescribed radiation to a tumor while protecting the surrounding tissue. Below each treatment type is explained more in detail.

3D conformal radiation therapy

This type of technique is a common option in radiation therapy in which it uses images from CT, MRI, and PET scans to create a precise plan for the treatment area. The process allows doctors to sculpt radiation beams to the shape of a tumor and often used in instances where the tumor is oddly shaped or if the tumor lies close to healthy tissue/ organs. The radiation beams can then be directed at the target from several angles as needed.

Intensity-modulated radiation therapy (IMRT)

Intensity-modulated radiation therapy (IMRT) is an advanced type of 3-D conformal radiation therapy to treat cancer and noncancerous tumors. IMRT is used by multiple small photons and proton beams aimed at targeted tumor cells with varied, controlled intensity. During each treatment, the beam shape and the beam strength will continue to change to give higher doses to certain parts of the tumor as needed. Due to the greater level of accuracy, IMRT is a possible treatment option for patients that may have reached the maximum allowable dose from conventional radiation therapy with reoccurring tumors.

Image-guided radiation therapy (IGRT)

Image-guided radiation therapy (IGRT) is a form of IMRT. What sets this type of treatment apart from IMRT is that it not only uses imaging scans before radiation sessions begin but also uses them during the actual radiation therapy session. Tumors can shift inside the body due to breathing or other body movements that can sometimes be hard to control. IGRT allows doctors to locate and track tumors during the procedure to deliver more precise radiation therapy. Technical adjustments can be made by the radiation oncologists when the tumor moves outside of the targeted area helping to limit radiation exposure that could damage healthy tissues nearby and decrease common radiation side effects.
