The doctor uses ultrasound and X-ray pictures to make sure the seeds are in the right place. A special computer software program is used to make sure the prostate gland is completely covered by just the right dose of radiation (see Figure 4) to ensure that all cancer cells present in the prostate have been completely treated.

A deviated septum is an abnormal condition in which the top of the cartilaginous ridge leans to the left or the right, causing obstruction of the affected nasal passage. It is common for nasal septa to depart from the exact centerline; the septum is only considered deviated if the shift is substantial or causes problems. [3]
This imaging modality uses a wide beam of X-rays for image acquisition and is the first imaging technique available in modern medicine. Fluoroscopy produces real-time images of internal structures of the body in a similar fashion to radiography, but employs a constant input of X-rays, at a lower dose rate.
A device used in tomography is called a tomograph, while the image produced is a tomogram. In many cases, the production of these images is based on the mathematical procedure tomographic reconstruction, such as X-ray computed tomography technically being produced from multiple projectional radiographs. Many different reconstruction algorithms ...
The images may also be used to check for other requirements of some types of treatment, such as full or empty bladder, empty rectum, etc. [8] [27] The same cone beam beam source and detector can alternatively be used to take simple X-ray positioning images if the organ shows particularly well on X-ray or if Fiducial markers have been inserted ...

The prostate is an accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found in all male mammals. [1] It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the bladder, with the urethra passing through it.
