Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
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 ...
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.
Therefore, many doctors will postpone invasive treatment until a year after the surgery. Urinary incontinence – most commonly stress incontinence – due to injury of the external sphincter system, may be prevented by taking the verumontanum of the prostate as a distal limiting boundary during TURP.
Contraindications to HIFU for prostate cancer include a prostate volume larger than 40 grams, which can prevent targeted HIFU waves from reaching the anterior and anterobasal regions of the prostate, anatomic or pathologic conditions that may interfere with the introduction or displacement of the HIFU probe into the rectum, and high-volume ...
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.

From the early days of radiation therapy, X-rays or gamma rays were used to develop large format radiographic films for inspection. With the introduction of cobalt-60 machines in the 1950s, radiation went deeper inside the body, but with lower contrast and poor subjective visibility.
