What is kV imaging in radiotherapy?
kV (kilo voltage) imaging systems provide your image-guided radiation therapy (IGRT) with digitally reconstructed radiographs (DRRs) to better direct radiation therapy. The device looks like right and left ‘arms’ that extend from the gantry of a linear accelerator.
Is kV or MV higher?
Conclusions. The imaging dose from kV radiographs and kV-CBCT scans is much less than from conventional MV portal imaging. Using kV imaging rather than MV imaging reduces patient doses and results in higher quality images.
Which is better IMRT or IGRT?
IGRT uses imaging with the therapy to increase the efficiency by improving the precision and accuracy of the treatment procedure. The IMRT therapy uses high-edged software and sophisticated hardware to vary the intensity and shape of radiation used for different parts of the treatment area.
What is kV CBCT?
Kilo-voltage cone beam computed tomography (kV-CBCT) integrated into the linear accelerator as a tool for image guided radiation therapy, was developed to acquire on-line volumetric and anatomical images [1].
Is CBCT kV or MV?
MV CBCT can be performed with standard radiotherapy equipment with additional software, whereas KV CBCT requires additional equipment as well. The use of CBCT in 3D positional verification could be particularly useful when detecting out-of-plane rotations.
Is IGRT and IMRT the same?
State-of-the-art radiation therapy at Genesis Healthcare incorporates intensity-modulated radiation therapy (IMRT) to allow the radiation dose to exactly match the highest cancer cell burden, and image-guided radiation therapy (IGRT) to allow the delivery of each treatment with a very high degree of accuracy.
Is CBCT KV or MV?
What is MV CBCT?
The MV CBCT system consists of a standard linear accelerator equipped with an amorphous-silicon flat panel electronic portal-imaging device adapted for mega-electron volt (MeV) photons.

How hard is it to match into oncology?
Matching into a hematology/oncology fellowship can be extremely competitive for international medical graduates (IMGs). According to the National Resident Matching Program (NRMP), there were 909 applicants for 638 positions offered at more than 160 U.S. hematology/oncology (HO) fellowships in 2021.
What type of radiation is Oncology?
The different types of external-beam radiation therapy are:
- Three-dimensional conformal radiation therapy (3D-CRT).
- Intensity modulated radiation therapy (IMRT).
- Proton beam therapy.
- Image-guided radiation therapy (IGRT).
- Stereotactic radiation therapy (SRT).
Is proton therapy better than IMRT?
Conclusions. Among patients with nonmetastatic prostate cancer, the use of IMRT compared with conformal radiation therapy was associated with less gastrointestinal morbidity and fewer hip fractures but more erectile dysfunction; IMRT compared with proton therapy was associated with less gastrointestinal morbidity.
Is radiation oncology easy?
To all new graduates of a radiation oncology residency: The first year as an attending can be the most challenging year in a medical career. This is no truer than in radiation oncology.
